20230114658
This application claims priority from Japanese Patent Application No. 2021-158536 filed on Sep. 28, 2021. The entire content of the priority application is incorporated herein by reference.
A consumable of a recording apparatus enabling recycling or reusing of a consumable once used, from standpoints of environmental protection and ecology, is known. The consumable is, for example, a cartridge.
When intending to reuse the consumable of the recording apparatus, the reusing is usually performed at a dedicated recycling factory. At the recycling factory, after used consumables in which consumable materials such as ink and toner are empty are collected, the consumables are made as recycled products (reused products) by re-dispensing consumable materials into the respective consumable so that users can use the products.
On the other hand, in recent years, a configuration is suggested in which, in order to properly and efficiently manage a consumable material in a consumable in a recording apparatus, a consumable memory is provided on the consumable-side, a communication unit is provided on a recording apparatus main body-side and various information is transmitted and received between the communication unit and the consumable memory by communication. In this case, the consumable memory stores use amount information representing, for example, a remaining amount and a used amount of the internal consumable material. As the consumable is mounted on the main body of the recording apparatus and the remaining amount of the consumable material is reduced, communication is performed from the communication unit in the main body of the recording apparatus to the consumable memory at an appropriate timing, so that the use amount information stored in the consumable memory is updated. As a result, in the consumable after use, the remaining amount represented by the use amount information in the consumable memory is almost zero.
When performing the above-described reusing for the consumable provided with such a consumable memory, the consumable is refilled with the consumable material by the re-dispensing described above. For this reason, it is necessary to perform initialization, such as returning the use amount information to a content corresponding to the filled state, i.e., for example, a 100% notation representing a full state.
However, since an amount of the consumable material required for re-dispensing may differ depending on a type and a size of the consumable, and the required communication specification and the like may differ depending on the specification of the consumable memory, a processing burden at the recycling factory may increase. In particular, in order to widely spread the reuse of consumables, it is necessary for as many waste disposal companies as possible to handle the recycling at the recycling factory. However, depending on the scale, capacity and the like of the disposal companies, there is a risk that the increase in the processing burden will be a hamper.
An object of the present disclosure is to provide a recording apparatus, a consumable for a recording apparatus, and an information processing method capable of reducing a processing load on a consumable memory at a recycling factory.
An aspect of the present disclosure is a recording apparatus including: a main body of the recording apparatus; and a consumable configured to be detachably attached to the main body of the recording apparatus, in which the consumable has at least a consumable memory that stores use amount information of a consumable material included in the consumable and recycling history information of the consumable, in which the main body of the recording apparatus has a communication unit configured to communicate with the consumable memory, and a processor, and in which the processor is configured to perform: first acquisition processing of acquiring the recycling history information from the consumable memory of the consumable mounted on the main body of the recording apparatus by communication via the communication unit; and determination processing of determining whether or not to perform initialization processing of initializing a value of the use amount information stored in the consumable memory, according to the acquired recycling history information.
In the aspect, the use amount information of the consumable and the recycling history information of the consumable are stored in the consumable memory. The use amount information in the stored contents is processed by the initiative of the recording apparatus-side.
By performing the first acquisition processing, the processor of the recording apparatus communicates with the consumable memory of the consumable mounted on the main body of the recording apparatus via the communication unit, and acquires the recycling history information.
The processor performs the determination processing of determining whether or not to perform the initialization processing of initializing the value of the use amount information stored in the consumable memory, based on the acquired recycling history information. When it is determined to perform the initialization processing, the initialization processing of the value of the use amount information in the consumable memory is performed.
According to the aspect, since the recording apparatus identifies the recycling history of consumable and the value of the use amount information is accordingly initialized as appropriate, it is not necessary to initialize the use amount information at the recycling factory, and it is sufficient to perform the simple processing of just updating the recycling history information. According to the first to third aspects, it is possible to reduce the processing load at the recycling factory.
According to the aspect, it is possible to reduce the processing load on the consumable memory at the recycling factory.
An embodiment of the present disclosure will be described with reference to the drawings.
A schematic configuration of a complex machine 200 according to one embodiment of the present disclosure is shown in
As shown in
The storage device 215 includes a volatile storage device 220 and a non-volatile storage device 230. The storage device 215 is an example of the main body memory. The volatile storage device 220 is, for example, a DRAM. The non-volatile storage device 230 is, for example, a flash memory. The non-volatile storage device 230 has a consumable-related information storage area 231 for storing consumable-related information relating to the ink cartridge 50, a program storage area 232, and a storage area 233 of a use amount initial value table, which will be described later.
The consumable-related information storage area 231 has a type information storage area 231A, a use amount information storage area 231B, and a use history information storage area 231C. These functions will be described later.
A variety of programs are stored in the program storage area 232, and the various programs include an operation program for the complex machine, including a print processing program relating to execution of an information processing method of the present embodiment based on flowcharts in
The display unit 240 is, for example, a liquid crystal monitor and can display various information about consumables. The operation unit 250 is a device configured to receive an operation made by a user. The user can input various instructions to the complex machine 200 by operating the operation unit 250. The communication interface 270 is a wired or wireless network interface for communicating with other apparatuses, and is connected to a network NT.
The scanner unit 280 is configured to optically read a document, which is a reading target, by using a photoelectric conversion element such as a CCD or a CMOS, thereby generating scan data representing a scanned image.
The printing unit 290 is configured to print an image on a sheet being conveyed by a predetermined method while taking out and conveying the sheet in a sheet feeding tray by a conveying mechanism (not shown). In the below, a case where printing is performed by an inkjet method will be described as an example. The printing unit 290 is configured to form an image on the sheet by using ink of the ink cartridge 50 detachably mounted on a cartridge holder 51, according to a print job transmitted from a mobile terminal 300 or a print job generated by itself based on an operation on the operation unit 250. Note that, the entire combination of the ink cartridge 50 mounted on the cartridge holder 51 and the complex machine 200 is an example of the recording apparatus.
Specifically, the printing unit 290 has an inkjet head mounted on a carriage, and printing is performed by the inkjet head ejecting the ink while the carriage moves the inkjet head in a main scanning direction. Note that, specifically, the ink cartridges 50 of respective ink colors of cyan ink, magenta ink, yellow ink and black ink are included. However, for sake of convenience, unless otherwise specified, they are simply referred to as “ink cartridge 50” without distinction.
The mounting detecting sensor 265 is, for example, a connector that conducts with an electrode of the ink cartridge 50 when the ink cartridge 50 is mounted on the cartridge holder 51, for example. The processor 210 can identify whether the ink cartridge 50 is mounted on the cartridge holder 51, based on a detection result of the mounting detecting sensor 265.
The processor 210 is a device configured to perform data processing, and is, for example, a CPU. Note that, the processor 210 is an example of a processor in the main body of the recording apparatus. By executing the print processing program stored in the program storage area 232, the processor 210 is configured to perform various processing shown in
The cartridge holder 51 is provided with an opening/closing cover (not shown) that can be opened/closed, and when the ink cartridge 50 is mounted or demounted with respect to the cartridge holder 51, the opening/closing cover is opened, and after the mounting or demounting, the opening/closing cover is closed. The opened state and the closed state of the opening/closing cover are detected by the cover sensor 275 by a known method, and the corresponding detection signals are input to the processor 210.
Note that, the processor 210 may be configured to identify whether the ink cartridge 50 is mounted on the cartridge holder 51, based on the detection result by the cover sensor 275, instead of the mounting detecting sensor 265.
The communication unit 285 is, for example, a terminal or the like, and is electrically connected to the cartridge memory 115 via electrodes 65A to 65C of the ink cartridge 50 mounted on the cartridge holder 51.
As shown in
The cartridge chip 64 is a printed circuit board (PCB), and includes a substrate 63, electrodes 65A to 65C, a cartridge memory 115, and a controller 110. Note that, the cartridge memory 115 is an example of the consumable memory.
The substrate 63 is a printed wiring board (PWB), and is made of glass epoxy, paper phenol, or the like. The substrate 63 is attached to a surface of the ink cartridge 50.
The electrodes 65A to 65C are formed on the substrate 63. These electrodes 65A to 65C function as an interface for communicating with the communication unit 285 of the complex machine 200.
In a state where the ink cartridge 50 is mounted on the cartridge holder 51, the respective electrodes 65 contact and are electrically connected to respective contact points 142A to 142C of the communication unit 285. Specifically, the electrode 65A contacts and is electrically connected to the contact point 142A, the electrode 65B contacts and is electrically connected to the contact point 142B, and the electrode 65C contacts and is electrically connected to the contact point 142C. Note that, the number of the electrodes 65 is determined according to the number of the contact points 142 of the communication unit 285, and is not limited to three.
The cartridge memory 115 has a volatile storage area 120 and a non-volatile storage area 130 that is an EEPROM of a non-volatile semiconductor memory.
The non-volatile storage area 130 has a first storage area 131, a second storage area 132, a third storage area 133, a program storage area 135, and a number-of-initializations count value storage area 136. A variety of programs are stored in the program storage area 135, and the various programs include a program for the ink cartridge 50, including an information processing program relating to execution of the information processing method of the present embodiment based on flowcharts in
The volatile storage area 120 may also be a volatile semiconductor memory, for example, an SRAM or a DRAM.
Note that, in the volatile storage area 120 or the non-volatile storage area 130, a latch circuit or a magnetic memory may also be adopted instead of the semiconductor memory.
The controller 110 has a writing function to a predetermined address of the cartridge memory 115 when a predetermined signal is detected at the electrode 65A.
In addition, the controller 110 has a function of, when the processor 210 of the complex machine 200 reads out information about the ink cartridge 50 stored in the cartridge memory 115 via the electrode 65B and the contact point 142B, transmitting the information about the ink cartridge 50 from the cartridge memory 115 to the electrode 65B.
The controller 110 is configured by an electronic circuit having the above functions, and is configured to perform various processing shown in
Note that, the controller 110 is not limited to the electronic circuit, and may be provided with, for example, a CPU capable of performing calculations, thereby realizing the above functions.
The processor 210 of the complex machine 200 can acquire various information from the cartridge memory 115 of the ink cartridge 50 connected via the communication unit 285 and the electrodes 65A to 65C. Note that, hereinafter, in the present specification, the processing “acquisition” by the processor 210 represents processing of writing information in a non-volatile storage area to a volatile area such as a DRAM, for example. The same applies to the controller 110. Thereby, the processor 210 can identify a type of the ink cartridge 50 mounted on the cartridge holder 51, based on the acquired information. The identification result is associated with a cartridge ID and a model number of the ink cartridge 50 by the processor 210, and is stored at any time in the type information storage area 231A of the consumable-related information storage area 231.
At this time, in the complex machine 200, an ink remaining amount or an ink used amount of the ink cartridge 50 mounted on the cartridge holder 51 is acquired at any time by the processing of the processor 210 by a known method. Then, when the ink remaining amount decreases and reaches a predetermined remaining amount threshold value, or when the ink used amount increases and reaches a predetermined used amount threshold value, it is possible to display on the display unit 240 that the ink cartridge 50 should be replaced. This makes it convenient for the user to replace the ink cartridge 50.
Note that, the ink remaining amount and the ink used amount are collectively referred to as “use amount” as appropriate below, and the information representing the same is referred to as “use amount information”. The use amount information acquired as described above can be written to the cartridge memory 115 by processing, which will be described later. In this case, the processor 210 can identify how much the use amount of the ink cartridge 50 is, based on the information acquired via the communication unit 285 while the ink cartridge 50 is mounted on the cartridge holder 51. The identification result, i.e., the use amount information of the ink cartridge 50 is associated with the cartridge ID and the model number by the processor 210, which is then stored at any time in the use amount information storage area 231B of the consumable-related information storage area 231.
Further, when the ink remaining amount or the ink used amount, i.e., the use amount information of the ink cartridge 50 mounted on the cartridge holder 51 is acquired at any time, as described above, the processor 210 stores the history in the use history information storage area 231C, as the use history information.
In the above configuration, the feature of the present embodiment is a processing aspect of the information stored in the cartridge memory 115 when performing reusing of the ink cartridge 50. An outline thereof will be described with reference to
That is, as described above, when performing reusing of the ink cartridge 50 once used, the recycling processing is usually performed at a dedicated recycling factory. As shown in
On the other hand, when the use amount information of ink is stored in the cartridge memory 115 as described above, the use amount information stored in the cartridge memory 115 is updated as appropriate as the ink cartridge 50 is used and the remaining amount of ink decreases. As a result, in the ink cartridge 50 after use, the remaining amount represented by the use amount information in the cartridge memory 115 is almost zero. When the ink cartridge 50 collected in this state is subjected to recycling at the recycling factory, the ink cartridge 50 is refilled with ink by the re-dispensing. For this reason, it is necessary to initialize the use amount information at the recycling factory, such as returning the use amount information to the content corresponding to the filled state, i.e., for example, a 100% notation representing a full state (refer to (c) in
In the specification of the present application, “initialization” means “the initial value of the use amount information is written as an amount of ink that can be used again as a recycled product”.
In addition, this initialization is not limited to writing the same value of the use amount information as that at the time of the first factory shipment as described above, and it is sufficient when a value of an amount that can be used again as a recycled product is written. For example, a value corresponding to 50% or more and less than 100% of the value at the time of the factory shipment, which is less than a value of the use amount information at the time of the first factory shipment, may be written as the value at the time of initialization.
Further, the value at the time of initialization does not have to completely match an amount of ink actually filled. For example, the ink cartridge 50 may be filled with ink of an amount exceeding the value at the time of initialization.
However, since an amount of the ink required for re-dispensing may differ depending on a type and a size of the ink cartridge and the required communication specification and the like may differ depending on the specification of the cartridge memory 115, a processing burden at the recycling factory may increase. In particular, in order to widely spread the reuse of consumables, it is necessary for as many waste disposal companies as possible to handle the recycling at the recycling factory. However, depending on the scale, capacity and the like of the disposal companies, there is a risk that the increase in the processing burden will be a hamper.
In the present embodiment, as shown in
Unlike the initialization of the use amount information described above, since the updating of the recycling history information is not affected by the type and size of the ink cartridge 50, the specification of the cartridge memory 115, and the like, and just changes the information from “no recycling history” to “there is a recycling history”, the burden on the recycling factory-side can be small.
In the present embodiment, when the recycled and shipped ink cartridge 50 is mounted on the printing apparatus P, the use amount information is initialized in the printing apparatus P ((b) in
As described above, in the present embodiment, the initialization of the use amount information is performed on the printing apparatus P-side, and the recycling factory updates only the recycling history information, so that it is possible to reduce the processing load on the recycling factory-side.
In order to realize the above method, the processing performed by the processor 210 of the complex machine 200 and the controller 110 of the ink cartridge 50 of the present embodiment will be described sequentially with reference to
First, the processing performed by the processor 210 of the complex machine 200 will be described with reference to the flowcharts of
In
In step S10, in the processor 210, the recycling history information and the capacity information transmitted from the ink cartridge 50 in response to the first transmission command in step S5 are received and acquired. The processing performed by the processor 210 in steps S5 and S10 is an example of the first acquisition processing.
In step S15, in the processor 210, it is determined whether the recycling history information acquired in step S10 is “0x00” representing “no recycling history” or “0x81” representing “use amount initialization completed” (which will be described later in detail). When the recycling history information is “0x00” or “0x81”, it is determined Yes to end the flow. That is, in this case, it is determined in step S15 that the initialization of the use amount information in step S30, which will be described later, is not executed. When the recycling history information is neither “0x00” nor “0x81”, No is determined and the processing proceeds to step S20.
In step S20, in the processor 210, it is determined whether the recycling history information acquired in step S10 is “0x01” representing “there is a recycling history”. When the recycling history information is not “0x01”, No is determined, and after predetermined error processing is performed in step S25, this flow ends. When the recycling history information is “0x01”, it is determined Yes to proceed to step S30. That is, in this case, it is determined in step S20 that the initialization of the use amount information in step S30, which will be described later, is executed.
In steps S15 and S20, it is determined whether the initialization of the use amount information of step S30 is executed according to the value of the recycling history information acquired in step S10. Therefore, steps S15 and S20 are examples of the determination step, and the processing performed by the processor 210 in steps S15 and S20 is an example of the determination processing.
In step S30, initialization command transmission processing for instructing the initialization of the use amount information is performed. The detailed contents of step S30 are shown in the flowchart of
In
In the processor 210, the use amount initial value table shown in
In step S36, in the processor 210, a first initialization command is transmitted to the ink cartridge 50. The first initialization command is a command for instructing the controller 110 to write the use amount initial value acquired in step S34 to the second storage area 132 to initialize the value of the use amount information, to update the recycling history information in the first storage area 131 from “0x01” to “0x81” and to perform an increment of increasing the number of initializations stored in the number-of-initializations count value storage area 136 by 1. Note that, the number of initializations of the count value storage area 136 is set to 0 in the brand-new ink cartridge 50, for example, at the time of manufacturing. The processing performed by the processor 210 in step S36 is an example of the first initialization command transmission processing.
When step S36 is completed, the processing returns to
Processing performed by the controller 110 of the ink cartridge 50 will be described with reference to
In
In step S60, by the controller 110, the recycling history information is read out from the first storage area 131 of the cartridge memory 115, the capacity information is read out from the third storage area 133, and these information are transmitted to the complex machine 200.
In step S65, in the controller 110, it is determined whether the first initialization command transmitted from the complex machine 200 in step S36 of
In step S70, by the controller 110, as a part of the writing processing, the use amount initial value received and acquired in step S65 is written to the second storage area 132, whereby the value of the use amount information in the second storage area 132 is initialized.
The processing in which the controller 110 executes step S70 is an example of the use amount information writing processing. In addition, the processing performed by the processor 210 in step S36 of
In step S75, by the controller 110, the recycling history information in the first storage area 131 is updated to “0x81”.
As described above, the recycling history information of the brand-new ink cartridge 50 is “0x00”. The recycling history information of the ink cartridge 50 recycled at the recycling factory is “0x01”. When the ink cartridge 50 after recycling is mounted on the complex machine 200, the recycling history information is set to “0x81” in step S75.
The end “0” of the recycling history information “0x00” of the brand-new ink cartridge 50 and the end “1” of the recycling history information “0x01” and “0x81” of the ink cartridge 50 after recycling represent whether the ink cartridge is a brand-new product without a recycling history or a recycled product with a recycling history. The ends “0” and “1” are examples of the first information part.
The third “0” of the recycling history information “0x01” of the ink cartridge 50 after recycling at the recycling factory, and the third “8” of the recycling history information[0x81] of the ink cartridge 50 mounted on the complex machine 200 after recycling represent whether there is an initialization history of the use amount information when there is a recycling history. The thirds “0” and “8” are examples of the second information part, the ink cartridge 50 after recycling at the recycling factory is an example of an uninitialized recycled product, and the ink cartridge 50 mounted on the complex machine 200 after recycling and subjected to the initialization of the use amount information in step S75 is an example of the initialized recycled product.
In step S80, by the controller 110, the number-of-initializations count value stored in the number-of-initializations count value storage area 136 is increased only by one.
Thereafter, this flow ends.
As described above, in the present embodiment, the ink use amount information and the recycling history information of the ink cartridge 50 are stored in the cartridge memory 115. Of the stored contents, the use amount information is processed by the initiative of the complex machine 200-side.
By executing step S5 and S10, the processor 210 of the complex machine 200 communicates with the cartridge memory 115 of the ink cartridge 50 mounted on the complex machine 200 via the communication unit 285, and acquires the recycling history information.
Based on the acquired recycling history information, steps S15 and S20 are executed by the processor 210, and it is determined whether or not to perform the initialization processing of initializing the value of the use amount information stored in the cartridge memory 115. When it is determined to perform the initialization processing, the value of the use amount information of the cartridge memory 115 is initialized in steps S36 and S70.
According to the present embodiment, since the complex machine 200 identifies the recycling history of the ink cartridge 50 and the value of the use amount information is accordingly initialized as appropriate, it is not necessary to perform the initialization of the use amount information at the recycling factory, and it is sufficient to perform the simple processing of just updating the recycling history information. According to the present embodiment, it is possible to reduce the processing load at the recycling factory.
In addition, in the present embodiment, in particular, the content of the recycling history information stored in the cartridge memory 115 of the ink cartridge 50 includes the end “0” or “ 1”, which is the first information part, and the end “0” or “8”, which is the second information part.
The first information represents whether the ink cartridge 50 is a recycled product with a recycling history or a brand-new product without a recycling history. The second information represents whether the ink cartridge 50 is an initialized recycled product with an initialization history of the use amount information or an uninitialized recycled product without the initialization history when the ink cartridge 50 is a recycled product.
According to the present embodiment, since the recycling history information includes both the information about the presence/absence of the recycling history and the information about the presence/absence of the initialization of the use amount information accompanying the recycling, it is possible to securely reduce the processing load at the recycling factory, as compared to a case where these information are separately divided.
In addition, in the present embodiment, particularly, when the acquired recycling history information represents that the ink cartridge 50 is an initialized recycled product or that the ink cartridge 50 is a brand-new product, the processor 210 determines not to perform the initialization processing.
When the ink cartridge 50 is a brand-new product, the value of the use amount information has been initialized at the manufacturing factory at the time of manufacturing, so that it is not necessary to re-initialize the use amount information in the complex machine 200 on which the ink cartridge 50 is mounted. When the ink cartridge 50 is an initialized recycled product, the value of the use amount information has been initialized at the recycling factory, so that it is not necessary to re-initialize the use amount information in the complex machine 200 on which the ink cartridge 50 is mounted
According to the present embodiment, when the ink cartridge 50 is a brand-new product or an initialized recycled product, it is possible to appropriately handle the ink cartridge without unnecessary processing.
Further, in the present embodiment, in particular, when the acquired recycling history information represents that the ink cartridge 50 is an uninitialized recycled product, the processor 210 determines to perform the initialization processing.
In the present embodiment, when the ink cartridge 50 is an uninitialized recycled product, the use amount information is re-initialized in the complex machine 200, unlike the case where the ink cartridge 50 is a brand-new product or an initialized recycled product.
According to the present embodiment, when the ink cartridge 50 is an uninitialized recycled product, the value of the use amount information is initialized, so that the processing load at the recycling factory can be reduced.
Further, in the present embodiment, in particular, the ink cartridge 50 is provided with the controller 110 configured to control the information reading and writing with respect to the cartridge memory 115, and the updating of the use amount information using the initial value of the use amount information is finally performed by the controller 110 of the ink cartridge 50 (step S36).
In the present embodiment, the initialization command transmission processing is performed by step S36 executed by the processor 210. In the storage device 215, the use amount initial value of each type of the ink cartridge 50 in the recycling completion state is stored. The first initialization command is transmitted to the controller 110 of the cartridge memory 115, so that the initialization processing of initializing the value of the use amount information by writing
the use amount initial value acquired from the storage device 215 to the second storage area 132 of the cartridge memory 115 by the controller 110 is performed (step S70).
According to the present embodiment, since the initialization processing of initializing the value of the use amount information is performed using the use amount initial value stored in the storage device 215, the storage capacity of the cartridge memory 115 can be reduced, as compared to a case where the use amount initial value is stored in the cartridge memory 115.
Further, in the present embodiment, in particular, the capacity information of the ink cartridge 50 is stored in the third storage area 133 of the cartridge memory 115. The processor 210 acquires the capacity information transmitted from the controller 110, based on the first transmission command in steps S5 and S10, accesses the storage device 215, based on the capacity information (step S32), and refers to the use amount initial values of the various ink cartridges 50 stored in advance in the storage device 215 to acquire the corresponding use amount initial value in step S34.
According to the present embodiment, it is possible to perform the initialization processing by referring to the use amount initial values of the various ink cartridges 50 stored in the storage device 215 and acquiring and writing an appropriate use amount initial value to the second storage area 132 of the cartridge memory 115 .Even when the product lineup or capacity information of the ink cartridge 50 changes, it is sufficient to appropriately correct or update the stored content of the storage device 215 on the complex machine 200-side, so that it is possible to smoothly deal with the change.
Note that, the present disclosure is not limited to the above embodiment, and, for example, modified embodiments such as (1), (2) and (3) below are also included in the technical scope. The modified embodiments will be sequentially described below. The parts equivalent to the above embodiment are denoted with the same reference signs, and the descriptions thereof are appropriately omitted or simplified.

The configuration shown in
The processing performed by the processor 210 of the complex machine 200 and the controller 110 of the ink cartridge 50 of the present embodiment so as to implement the above method of the present modified embodiment will be described with reference to
First, the processing performed by the processor 210 of the complex machine 200 will be described with reference to a flowchart of
In
First, in step S7, in the processor 210, a second transmission command is transmitted to the ink cartridge 50. The second transmission command is a command for instructing the controller 110 to read out and transmit the recycling history information and the use amount initial value from the first storage area 131 and the fourth storage area 134 of the cartridge memory 115. In the fourth storage area 134, specific numerical information such as 15[ml], 50[ml], 100[ml] and the like is stored in conformity to the size of the ink cartridge 50, the maximum storage capacity of the ink, and the like.
In step S11, in the processor 210, the recycling history information and the use amount initial value transmitted from the ink cartridge 50 in response to the second transmission command in step S7 are received and acquired. The processing performed by the processor 210 in steps S7 and S11 is an example of the first acquisition processing of the present modified embodiment. Thereafter, in steps S15 to S30, the equivalent processing to that of the above embodiment is performed.
The detailed contents of the initialization command transmission processing performed in step S30 in the present modified embodiment are shown in a flow of

The third initialization command is a command for instructing the controller 110 to copy the stored content of the fourth storage area 134 to the second storage area 132 to initialize the value of the use amount information, to update the recycling history information in the first storage area 131 from “0x01” to “0x81” and to perform an increment of increasing the number of initializations stored in the number-of-initializations count value storage area 136 by 1. Step S38 is an example of the initialization step, and the processing performed by the processor 210 in step S38 is an example of the third initialization command transmission processing.

In step S70', by the controller 110, the use amount initial value stored in the fourth storage area 134 is read out, and as a part of the writing processing, the value is copied to the second storage area 132, so that the value of the use amount information in the second storage area 132 is initialized.

The processing contents of steps S75 and S80 are similar to those in
In the present modified embodiment, the similar effects to the above embodiment are obtained.
In the present modified embodiment, by executing steps S9 and S13, the processor 210 of the complex machine 200 communicates with the cartridge memory 115 of the ink cartridge 50 mounted on the complex machine 200 via the communication unit 285, and acquires the recycling history information.
Based on the acquired recycling history information, steps S15 and S20 are executed by the processor 210, and it is determined whether or not to execute step S38 of initializing the value of the use amount information stored in the cartridge memory 115. When it is determined to execute step S38 based on the recycling history information, the value of the use amount information of the cartridge memory 115 is initialized by the processor 210 in step S38.
According to the present modified embodiment, as in the above embodiment, it is not necessary to perform the initialization of the use amount information at the recycling factory, and it is sufficient to perform the simple processing of just updating the recycling history information, so that it is possible to reduce the processing load at the recycling factory.
In addition, in the present modified embodiment, particularly, the processor 210 transmits the third transmission command to the controller 110 of the cartridge memory 115 by steps S9 and S13, thereby acquiring the recycling history information read out and transmitted from the first storage area 131 by the controller 110 based on the third transmission command (step S13). When the recycling history information is acquired, the processor 210 executes step S38 to transmit the third initialization command to the controller 110, so that the initialization processing of initializing the value of the use amount information by reading out the use amount initial value stored in the fourth storage area 134 and copying and writing the same to the second storage area 132 by the controller 110 is performed (step S70').
According to the present embodiment, the value of the use amount information is initialized by simply copying the use amount initial value stored in advance in the cartridge memory 115, so that the processing on the complex machine 200-side can be further simplified.
Note that, in the above embodiment and the respective modified embodiments, the command is transmitted from the processor 210 of the complex machine 200 to the controller 110 of the ink cartridge 50, so that the controller 110 reads out and writes information with respect to the cartridge memory 115. However, the present disclosure is not limited thereto. That is, the processor 210 of the complex machine 200 may be configured to read out and write information with respect to the cartridge memory 115 via the communication unit 285 and the electrodes 65A to 65C without going through the controller 110.
In this case, steps S5, S7 and S9 described above are omitted, and in subsequent steps S10, S11 and S13, each information is directly acquired from the cartridge memory 115 by the processor 210. Further, in steps S36, S37 and S38, the processor 210 directly writes the use amount initial value to the second storage area 132, instead of outputting the first to third initialization commands to the controller 110 and causing the controller 110 to write the use amount initial value to the second storage area 132. The same applies to the updating of the recycling history information and the incrementing of the number-of-initializations count value. That is, in these cases, the initialization processing of initializing the value of the use amount information in the second storage area 132 is performed by the processor 210.
Further, in the above case, the controller 110 may be omitted in the ink cartridge 50, and the processor 210 may directly read out and write information with respect to the cartridge memory 115 via the electrodes 65A to 65C.
Further, in the above, the ink has been taken as an example of the consumable material, and the ink remaining amount or the ink used amount of the ink cartridge 50 has been described as an example of the use amount information. However, the present disclosure is not limited thereto. For example, when a laser type complex machine 200 is used instead of an inkjet type, toner may be used as a consumable material and a remaining amount or use amount of toner in a toner cartridge may be treated as the use amount information, or a drum may be used as a consumable and a remaining life thereof may be treated as the use amount information.
