20230382141
The present application is based on, and claims priority from JP Application Serial Number 2022-088364, filed May 31, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a liquid ejecting system.
In a liquid ejecting apparatus such as an ink jet printer, generally, liquid such as ink is ejected from a liquid ejecting head by supplying a drive pulse to a drive element such as a piezoelectric element. For example, JP-A-2021-030689 discloses a liquid ejecting apparatus including a plurality of heads.
In recent years, there has been a business model in which a head manufacturer sells only a head to a printer manufacturer. Here, the head manufacturer may want to update the head in some way after shipping the head. For example, when some kind of defect is found for the first time after the head is shipped, there is a request to notify users of the printer sold by the printer manufacturer as soon as possible. Further, even when the program incorporated in the head is improved after the head is shipped, there is also a request that the users want to update the program as soon as possible. However, in the sales of the head, the printer manufacturer and the like intervenes between the head manufacturer and the user, and thus it is likely that the head manufacturer is not able to specify the user, and as a result, is unable to immediately inform the user about information on updates as described above.
According to an aspect of the present disclosure, there is provided a liquid ejecting system including a head unit that ejects liquid, a first output portion that outputs unique information unique to the head unit to an external server, a first input portion to which update information about the head unit is input from the external server in association with the unique information, and a notification portion that notifies a user based on the update information.
Hereinafter, preferred embodiments according to the present disclosure will be described with reference to the accompanying drawings. In the drawings, the dimensions and scale of each portion are appropriately different from the actual ones, and some portions are schematically shown for easy understanding. Further, the scope of the present disclosure is not limited to the embodiments unless it is stated in the following description that the present disclosure is particularly limited.
Here, each of the liquid ejecting apparatuses 100_1 to 100_3 is provided by a printer manufacturer that manufactures printer main bodies, which will be described later. The liquid ejecting apparatuses 100_1 to 100_3 may be provided by the same manufacturer or may be provided by different manufacturers. Each of first processing apparatuses 200_1 to 200_3 may use a property of a user or may be provided by a printer manufacturer. On the other hand, a head unit 110 incorporated in each of the liquid ejecting apparatuses 100_1 to 100_3 is provided by a head manufacturer that manufactures heads, which will be described later. The external server 300 may be any server as long as the head manufacturer can provide the necessary services to the user, and may be owned by the head manufacturer itself, or by a third party other than the head manufacturer. The second processing apparatus 400 is owned by the head manufacturer itself. The second processing apparatus 400 is maintained and managed by the head manufacturer.
For example, the user using the liquid ejecting apparatus 100_1 owns the liquid ejecting apparatus 100_1, the first processing apparatus 200_1, and the head unit 110. On the other hand, although the user does not own the external server 300, the first processing apparatus 200_1 owned by the user is communicably connected to the external server 300 through a communication network NW. When the external server 300 is owned by a third party, the second processing apparatus 400 is communicably connected to the external server 300 through the communication network NW (not shown).
For example, when a printer manufacturer for manufacturing a printer main body using a head purchased from the head manufacturer uses the printer main body manufactured by itself, the printer manufacturer is the user. Further, for example, when a printer manufacturer that manufactures a printer main body using a head purchased from the head manufacturer sells the printer main body to a third party and the third party uses the printer main body, the third party is the user.
The liquid ejecting apparatus 100_1 is communicably connected to the first processing apparatus 200_1. The liquid ejecting apparatus 100_2 is communicably connected to the first processing apparatus 200_2.

As described above, the liquid ejecting apparatuses 100_1 to 100_3 correspond to the first processing apparatuses 200_1 to 200_3, respectively, and are communicably connected to the first processing apparatuses 200_1 to 200_3. In the following, without distinguishing each of the liquid ejecting apparatuses 100_1 to 100_3 from the others, they may be referred to as the liquid ejecting apparatus 100. Without distinguishing each of the first processing apparatuses 200_1 to 200_3 from the others, they may be referred to as the first processing apparatus 200.

The input device 320 is a device that receives an operation from the user, and is configured in the same manner as the input device 220 described above. The communication device 330 is a circuit capable of communicating with each first processing apparatus 200, and is configured in the same manner as the communication device 230 as described above. The communication device 330 may be integrated with the processing circuit 350.
Here, the communication device 330 receives the unique information D1 and transmits the update information D2 by communicating with the first processing apparatus 200. That is, the communication device 330 functions as a second connection portion 331 that is communicably connected to the first connection portion 231. In addition, the communication device 330 transmits the unique information D1 by communicating with the second processing apparatus 400, as needed.
The storage circuit 340 is a device that stores various programs executed by the processing circuit 350 and various data processed by the processing circuit 350, and is configured in the same manner as the storage circuit 240 described above. The storage circuit 340 stores a program PG2, the unique information D1, the update information D2, and correspondence information D4. When the first processing apparatus 200 transmits the arrangement information D3 together with the unique information D1, the arrangement information D3 is also stored in the storage circuit 340.
The program PG2 is a program that enables a computer to implement various functions necessary for generating the update information D2 according to the unique information D1. The correspondence information D4 is information regarding a correspondence relationship between the unique information D1 and the update information D2. For the correspondence information D4, any format is possible without being limited to a particular format; for example, the format is a lookup table showing the correspondence relationship between the unique information D1 and the update information D2. Further, the “generation of the update information D2” includes a case where one or more pieces of update information D2 are selected or extracted from a plurality of pieces of update information D2.
For example, after the head manufacturer manufactures and ships the head unit 110, in some cases, some deficiency may be found in the head unit 110 or the program PG0 mounted on the head unit 110 may be updated. In this case, the head manufacturer wants to notify the users of the information related to update, such as the deficiency notification or updates, but when the printer manufacturer is involved in the sale, the head manufacturer may not be able to specify the users. Therefore, the head manufacturer stores, in the external server 300, the correspondence relationship in which the update information D2 and the unique information D1 about the head unit corresponding to the update information D2 are associated with the external server 300, as the correspondence information D4. Then, when the unique information D1 is input to the external server 300 from the first processing apparatus 200 on the user side, the external server 300 determines whether or not the unique information D1 is included in the correspondence information D4. When the unique information D1 is included in the correspondence information D4, the external server 300 outputs the update information D2 corresponding to the unique information D1 to the first processing apparatus 200 in the correspondence information D4. In this way, even if the user cannot be specified on the head manufacturer side, the user can be notified of the update information D2 according to the unique information D1.
The processing circuit 350 is a device having a function of controlling each portion of the external server 300 and a function of processing various data, and is configured in the same manner as the processing circuit 250 described above. The processing circuit 350 functions as an output portion 351, an input portion 352, and a calculation portion 353 by reading the program PG2 from the storage circuit 340 and executing the program PG2.
The output portion 351 outputs the update information D2 through the second connection portion 331. For example, the output portion 351 outputs the update information D2 to the first processing apparatus 200 through the second connection portion 331, by using an instruction or the like issued by the user using the input device 220 as a trigger.
The unique information D1 is input to the input portion 352 through the second connection portion 331. For example, the unique information D1 is input from the first processing apparatus 200 to the input portion 352 through the second connection portion 331, by using an instruction or the like by the user using the input device 220 as a trigger.
The calculation portion 353 performs a calculation to generate the update information D2 according to the unique information D1. In the present embodiment, the calculation portion 353 performs a calculation to generate the update information D2 using the unique information D1 and the correspondence information D4.
Then, in step S102, the first processing apparatus 200 outputs the unique information D1 to the external server 300.
Specifically, in step S102, the first output portion 252 outputs the unique information D1 through the first connection portion 231 by using the acquisition of the unique information D1 as a trigger. A timing at which the unique information D1 is output to the first connection portion 231 is not limited to the time when the unique information D1 is acquired. For example, the first output portion 252 may transmit authentication information such as account information and a password for the user to the external server 300 when the first receiving portion 256 receives the input using an input image GD for the GUI to be described later, the external server 300 may transmit output permission information to the first processing apparatus 200 when the external server 300 succeeds in the authentication using the authentication information, and the first output portion 252 may output the unique information D1 to the external server 300 when the output permission information is received by the first processing apparatus 200.
Next, in step S103, the external server 300 inputs the unique information D1. The input is performed by the input portion 352. Then, in step S104, the external server 300 generates the update information D2 based on the unique information D1. The generation is performed by the calculation portion 353. The external server 300 may compare the unique information D1 with predetermined comparison information, and may cancel the processing after step S104 depending on the comparison result. In this case, the output portion 351 may output information indicating that the update information D2 is not provided.
Then, in step S105, the external server 300 outputs the update information D2 to the first processing apparatus 200. The output is performed by the output portion 351.
Next, in step S106, the first processing apparatus 200 inputs the update information D2. Specifically, in step S106, the update information D2 from the external server 300 is input to the first input portion 253 through the first connection portion 231. The first input portion 253 may notify the user as to whether or not the update information D2 is input from the external server 300 by using the display device 210 or the like, and the update information D2 from the external server 300 may be input only when the user inputs an instruction to permit an input by the input device 220 or the like.
Then, in step S107, the first processing apparatus 200 makes a notification based on the update information D2. The notification is performed by the notification portion 254. Specifically, the notification portion 254 displays a region RC3 based on the update information D2 in the display region 211.
When the above-described program PG1 is executed by the first processing apparatus 200, various information required to manage the liquid ejecting apparatus 100 is displayed in the display region 211 of the display device 210. Hereinafter, the display in the display region 211 will be described by taking Arrangement Examples 1 to 4 of the plurality of liquid ejecting heads 110a as examples. It should be noted that Arrangement Examples 1 to 4 are examples for convenience in describing the arrangement of the plurality of liquid ejecting heads 110a, and the present disclosure is not limited thereto.
In Arrangement Example 1, as shown in
The reception image GB is a GUI image for receiving an input of information required to generate the arrangement information D3 by operating the input device 220 by the user. The second receiving portion 257 generates the arrangement information D3 using the information input using the reception image GB.
The reception image GB includes regions RB1, RB2, and RB3. The region RB1 is a region for inputting the number of columns of the plurality of liquid ejecting heads 110a for each ink color. The region RB2 is a region for inputting the number of rows of the plurality of liquid ejecting heads 110a for each ink color. The region RB3 is a region for inputting the presence or absence of an offset. The offset will be described later with reference to
In the example shown in
For each of the regions RB1, RB2, and RB3, any region is possible as long as it can receive necessary information, and the mode is not limited to using the drop-down list and other known widgets can be applied.
The arrangement image GA includes a plurality of head display regions B1. The plurality of head display regions B1 are divided for each ink color.
Specifically, the plurality of head display regions B1 is divided into a cyan head region RA_C indicating the arrangement of a plurality of liquid ejecting heads 110a that use cyan ink, a magenta head region RA_M indicating the arrangement of a plurality of liquid ejecting heads 110a that use magenta ink, a yellow head region RA_Y indicating the arrangement of a plurality of liquid ejecting heads 110a that use yellow ink, and a black head region RA_B indicating the arrangement of a plurality of liquid ejecting heads 110a that uses black ink.
In the example shown in
The plurality of head display regions B1 have display modes varied depending on the arrangement of the plurality of liquid ejecting heads 110a.

As described above, by varying the position and the number of the head display regions B1 indicating the existence of the liquid ejecting heads 110a depending on the arrangement of the liquid ejecting heads 110a, the arrangement of the plurality of liquid ejecting heads 110a is displayed in the arrangement image GA.
In the present embodiment, among the eight head display regions B1 constituting the cyan head region RA_C, the head display region B1 corresponding to the liquid ejecting head 110a_C2 exhibits an error image B2 indicating an error state. In the example shown in
The head display region B1 can receive, from the user, an operation on the head display region B1 indicating that the liquid ejecting head 110a exists among the plurality of head display regions B1. The operation is received by the first receiving portion 256. When the first receiving portion 256 receives the operation, the display control portion 255 displays the property information about the target liquid ejecting head 110a in the display region 211. An example of the display will be described with reference to

In the region RC3, a notification from the head manufacturer is displayed based on the update information D2. For example, when the liquid ejecting head 110a to be operated with respect to the head display region B1 is deficient in the region RC3, display is performed to that effect. Here, when the liquid ejecting head 110a to be operated for the head display region B1 is deficient, for example, by displaying “notify” in the region RC3, a notification is issued to the effect that the use of the liquid ejecting head 110a to be operated with respect to the head display region B1 is not recommended. In this case, necessary information may be provided to the user later by the head manufacturer or the printer manufacturer in an appropriate method.
