Patent Application
20240004595
The present application is based on, and claims priority from JP Application Serial Number 2022-107683, filed Jul. 4, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a server device, a method of controlling a server device, and a printing system.
In the past, there has been known a technology of obtaining an operation log of a printer.
In, for example, JP-A-2021-135666 (Document 1), there is described an administrative server regularly obtaining an operation log of a printer.
However, in the server described in Document 1, since there are a variety of restrictions on the operation log to regularly be obtained, there is a possibility that it is not achievable to obtain information for identifying the cause of an error.
For example, in a usual operation log (e.g., an operation log regularly obtained), there is a restriction on a capacity of the operation log in order to prevent an influence on a printing operation of a printer when obtaining the operation log. Therefore, there is a possibility that there occurs an item which cannot be obtained in the usual operation log.
An aspect for solving the problems described above is a server device to be coupled to a printer so as to communicate with each other, the server device including an instruction unit configured to transmit an instruction of making the printer perform a printing operation when an error occurs in the printer, and a first acquisition unit configured to make the printer generate a first operation log as a log related to the printing operation based on the instruction, and then obtain the first operation log from the printer.
Another aspect for solving the problems described above is a method of controlling a server device to be coupled to a printer so as to communicate with each other, the method including an instruction step of transmitting an instruction of making the printer perform a printing operation when an error occurs in the printer, and a first acquisition step of making the printer generate a first operation log as a log related to the printing operation based on the instruction, and then obtaining the first operation log from the printer.
Still another aspect for solving the problems described above is a printing system including a printer, and a server device to be coupled to the printer so as to communicate with each other, wherein the server device includes an instruction unit configured to transmit an instruction of making the printer perform a printing operation when an error occurs in the printer, and a first acquisition unit configured to make the printer generate a first operation log as a log related to the printing operation based on the instruction, and then obtain the first operation log from the printer.
An embodiment of the present disclosure will hereinafter be described with reference to the drawings.
The printing system 1 is provided with a printer 100, a server device 200, and a client terminal device 300. The printer 100, the server device 200, and the client terminal device 300 are connected to each other via a network NW so as to be able to communicate with each other. The network NW is, for example, a WAN (Wide Area Network).
The printer 100 prints an image on a recording medium M. In the present embodiment, there is described when the printer 100 is, for example, a so-called inkjet-type large-format printer. Further, when an error occurs, the printer 100 transmits error information ER to the server device 200. Further, the printer 100 regularly (e.g., once per day) transmits an operation log PL to the server device 200.
The printer 100 corresponds to an example of a “printing device.”
The printer 100 will further be described with reference to
In the present embodiment, there is described when the printing system 1 includes a single printer 100 for the sake of convenience, but this is not a limitation. It is possible for the printing system 1 to include a plurality of printers 100.
Further, in the present embodiment, there is described when the printer 100 is the inkjet-type large-format printer, but the printer 100 can be a so-called business printer, or a home printer.
The server device 200 regularly receives the operation log PL from the printer 100. Further, the server device 200 transmits the operation log PL to the client terminal device 300.
Further, when the server device 200 receives the error information ER from the printer 100, the server device 200 transmits an instruction CM of setting a predetermined setting condition and executing a printing operation to the printer 100.
In the present embodiment, there is described when the server device 200 is connected to the printer 100 and the client terminal device 300 with an Ethernet (a registered trademark) cable or the like so as to be able to achieve wired communication with each other, but this is not a limitation. It is possible for the server device 200 to be connected to the printer 100 and the client terminal device 300 with Wi-Fi (a registered trademark) or the like so as to be able to achieve wireless communication with each other.
The client terminal device 300 is constituted by, for example, a personal computer, and receives the error information ER and the operation log PL from the server device 200. The user (e.g., a designer of the printer 100 or a maintenance staff of the printer 100) of the client terminal device 300 analyzes the operation log PL to identify the cause of the error information ER.
When the cause of the error cannot be identified, the user operates the client terminal device 300 to make the client terminal device 300 transmit identification-failure information NS to the server device 200. The identification-failure information NS represents that the cause of the error cannot be identified.
When the server device 200 receives the identification-failure information NS, the server device 200 transmits an instruction CM of setting a predetermined setting condition and executing a printing operation to the printer 100.
In the present embodiment, there is described when the printing system 1 includes a single client terminal device 300 for the sake of convenience, but this is not a limitation. It is possible for the printing system 1 to include a plurality of client terminal devices 300.
Further, in the present embodiment, there is described when the client terminal device 300 is constituted by a personal computer, but this is not a limitation. It is possible for the client terminal device 300 to be constituted by a smartphone, a tablet terminal, or the like.
Then, a configuration of the printer 100 will be described with reference to
The printer 100 is an inkjet-type large-format printer which ejects ink to the recording medium M to form an image on a printing surface of the recording medium M.
The printer 100 is provided with a print head 111 for ejecting the ink to the recording medium M. The printer 100 ejects a plurality of colors of ink from the print head 111 to thereby perform color printing. For example, the print head 111 ejects the five colors of ink, namely yellow ink, magenta ink, cyan ink, black ink, and white ink, from respective nozzles different from each other. The number of colors of the ink used by the printer 100 is not particularly limited. A platen 112 is arranged at a position opposed to the print head 111. The platen 112 supports the recording medium M at a position opposed to the print head 111 in a support surface 112A formed like a plane.
The recording medium M is not particularly limited as long as the recording medium M has a sheet-like shape, and it is possible to use paper, a sheet made of synthetic resin, cloth, and so on. The recording medium M can be a cut sheet cut to have a standard size, but in the present embodiment, there is described a configuration in which a long recording medium M is used.
The printer 100 has a delivery roller 103 on which the recording medium M is wound around to form a roll shape. The printer 100 includes conveying rollers 105 and conveying rollers 106 for conveying the recording medium M delivered from the delivery roller 103.
Each of the conveying rollers 105 and the conveying rollers 106 nip the recording medium M with a pair of rollers to feed the recording medium M in a conveying direction F. The recording medium M printed by the print head 111 is wound by a wind-up roller 108. The conveying rollers 105 and the conveying rollers 106 are driven by a conveying motor not shown. Further, the delivery roller 103 and the wind-up roller 108 are driven by the conveying motor or another motor.
The conveying rollers 105 and the conveying roller 106 are arranged along a conveying path FW through which the recording medium M is conveyed in the printer 100, and convey the recording medium M in the conveying direction F in accordance with the control by a first controller 160 which will be described later with reference to
The printer 100 has a colorimeter 121 for performing colorimetry on the recording medium M printed by the print head 111. The colorimeter 121 is located downstream of the print head 111 in the conveying direction F, and performs the colorimetry on a print image formed on the printing surface of the recording medium M using the ink ejected by the print head 111.
It should be noted that it is possible to dispose a configuration for fixing the ink between the print head 111 and the colorimeter 121. For example, when the printer 100 performs printing using UV ink which cures due to ultraviolet rays, it is possible to arrange an ultraviolet irradiation device at downstream of the print head 111 in the conveying direction F. In this case, the colorimeter 121 is arranged at downstream of the ultraviolet irradiation device. Further, in the printer 100, it is possible to arrange a drying device for drying the ink at downstream of the print head 111. In this case, the colorimeter 121 is arranged at downstream of the drying device.
In the present embodiment, a position where the colorimeter 121 performs the colorimetry is described as a colorimetry position P. The colorimetry position P represents a position in the conveying direction F. In
Here, the print head 111 side of the recording medium M in a direction perpendicular to the support surface 112A of the platen 112 is described as an upper side of the conveying path FW. Each part of the colorimeter 121 is arranged at the upper side of the conveying path FW, and is opposed to a surface on which the print head 111 ejects the ink in the recording medium M.
The colorimeter 121 is arranged so as to be opposed to a support member 131. The support member 131 is located at an opposite side to the colorimeter 121 across the recording medium M, namely at a lower side of the conveying path FW. An upper surface of the support member 131 is shaped like a plane, and the upper surface of the support member 131 supports the recording medium M.
Then, a configuration of a first control device 150 of the printer 100 will be described with reference to

The first controller 160 is provided with a first processor 160A and a first memory 160B. The first controller 160 controls operations of constituents of the printer 100 shown in
For example, the print head 111 ejects the ink in accordance with an instruction from the first controller 160 to form a print image on the recording medium M.
Further, for example, the colorimeter 121 performs the colorimetry with colorimetric element not shown in accordance with an instruction from the first controller 160, and then outputs a colorimetric value to the first controller 160.
The first processor 160A is formed of a CPU (Central Processing Unit), a DSP (Digital Signal Processor), a microcomputer, or the like. The first processor 160A can be formed of a plurality of processors, or can also be formed of a single processor.
It is also possible for the first processor 160A to be hardware programmed so as to realize functions of constituents described later. In other words, it is possible for the first processor 160A to have a configuration in which a first control program PG1 is implemented as a hardware circuit. In this case, for example, the first processor 160A is formed of an ASIC (application specific integrated circuit) or an FPGA (field programmable gate array).

The first memory 160B can be provided with, for example, a ROM (Read Only Memory), an HDD (Hard Disk Drive), or an SSD (Solid State Drive) as the nonvolatile storage area. Further, it is possible for the first memory 160B to be provided with a volatile storage area to form a work area for temporarily storing the program to be executed by the first processor 160A and the data as the processing target. The first memory 160B can be provided with, for example, a RAM (Random Access Memory) as the volatile storage area.

Further, to the first controller 160, there are coupled a variety of sensors for performing detection related to the printing operation of the printer 100. For example, there are coupled a residual amount sensor for detecting a residual amount of the recording medium M wound around the delivery roller 103, and a medium sensor for detecting presence or absence of the recording medium M at detection positions at upstream and downstream of the platen 112. Further, it is possible to couple a variety of sensors for detecting clogging of the nozzles of the print head 111.
The first operation mechanism 170 is provided with a variety of keys, buttons, and so on, and receives operations from the user (e.g., an operator of the printer 100). Then, the first operation mechanism 170 generates an operation signal corresponding to the operation thus received, and then outputs the operation signal thus generated to the first controller 160. The first display mechanism 180 is provided with an LCD (Liquid Crystal Display) or the like, and displays a variety of images on the LCD in accordance with an instruction from the first controller 160.
The first communication interface 190 is provided with a connector and an interface circuit, and is coupled to the first controller 160. In the present embodiment, the first communication interface 190 is an interface for communicating with the server device 200 in accordance with, for example, the Ethernet (a registered trademark) standard.
Further, as shown in
The setting condition storage 166 stores a setting condition. The setting condition includes setting values to be set to the constituents of the printer 100, and print image data. The setting condition includes the “predetermined setting condition.” The “predetermined setting condition” is stored by the instruction receiver 163 in the setting condition storage 166. Further, the “predetermined setting condition” is read out by the print controller 161, and is then set to the printer 100.
The first log storage 167 stores a first operation log PL1 and a second operation log PL2.

Further, when an error occurs in the printer 100, the print controller 161 generates the error information ER, and then transmits the error information ER thus generated to the server device 200. The error information ER represents that the error has occurred. Further, it is possible for the error information ER to include information representing at least one of a type and a content of the error having occurred.
The second log generator 162 regularly (e.g., once a day) generates the second operation log PL2 as a log related to the usual printing operation of the printer 100. Further, the second log generator 162 makes the first log storage 167 store the second operation log PL2 thus generated. Further, the second log generator 162 transmits the second operation log PL2 to the server device 200. The “usual printing operation” means the printing operation other than the printing operation based on the instruction CM from the server device 200. In other words, the “usual printing operation” means the printing operation based on an instruction from the first control device 150.
The second operation log PL2 corresponds to an example of the operation log PL.
The second operation log PL2 will further be described with reference to
The instruction receiver 163 receives a first instruction CM1 for setting the predetermined setting condition to the printer 100. When the instruction receiver 163 has received the first instruction CM1, the print controller 161 sets the predetermined setting condition to the printer 100. Further, the print controller 161 makes the setting condition storage 166 store the predetermined setting condition.
The “predetermined setting condition” is a setting condition for identifying, for example, the cause of the error corresponding to the error information ER. Further, the “predetermined setting condition” is a setting condition for replicating, for example, the error corresponding to the error information ER. The “predetermined setting condition” is transmitted, for example, from the client terminal device 300 to the server device 200.
Further, the instruction receiver 163 receives a second instruction CM2 of making the printer 100 perform the printing operation from the server device 200.

The first instruction CM1 and the second instruction CM2 each correspond to an example of the instruction CM.
When the print controller 161 makes the printer 100 perform the printing operation based on the instruction CM from the server device 200, the first log generator 164 generates the first operation log PL1 as a detailed log related to the printing operation of the printer 100. Then, the first log generator 164 makes the first log storage 167 store the first operation log PL1 thus generated. Further, the first log generator 164 transmits the first operation log PL1 to the server device 200.

Further, the first communication controller 165 receives, for example, the first instruction CM1 and the second instruction CM2 from the server device 200.
Then, a configuration of the server device 200 will be described with reference to

The second operation log PL2 is obtained by the second acquisition unit 213, and is stored by the second acquisition unit 213 in the second log storage 216.
When an error has occurred in the printer 100, the instruction unit 211 transmits the second instruction CM2 of making the printer 100 perform the printing operation.
“When an error has occurred in the printer 100” includes the following two cases. First, there is cited when the error information ER representing that the error has occurred has been received from the printer 100. Then, there is cited when the determination unit 214 has determined that the error has occurred in the printer 100 based on the second operation log PL2.
Further, when the instruction unit 211 receives the identification-failure information NS representing that the cause of the error corresponding to the error information ER cannot be identified from, for example, the client terminal device 300, the instruction unit 211 transmits the second instruction CM2 of making the printer 100 perform the printing operation.

The second acquisition unit 213 obtains the second operation log PL2 from the printer 100. The second operation log PL2 is the operation log PL related to the usual printing operation of the printer 100.

Further, as shown in
The third log storage 315 stores the first operation log PL1 and the second operation log PL2. The first operation log PL1 is received from the server device 200 by the first receiver 311, and is stored by the first receiver 311 in the third log storage 315. The second operation log PL2 is received from the server device 200 by the second receiver 312, and is stored by the second receiver 312 in the third log storage 315.
The first receiver 311 receives the first operation log PL1 from the server device 200. Then, the first receiver 311 makes the third log storage 315 store the first operation log PL1.
The second receiver 312 receives the second operation log PL2 from the server device 200. Then, the second receiver 312 makes the third log storage 315 store the second operation log PL2.
The determination receiver 313 receives a determination operation by the user (e.g., the designer of the printer 100 or the maintenance staff of the printer 100) on whether or not an error has occurred in the printer 100 based on the second operation log PL2 via the third operation mechanism 320. In other words, when the second receiver 312 has received the second operation log PL2, the user determines whether or not an error has occurred in the printer 100 based on the second operation log PL2. Then, the determination operation representing the determination result is input to the third operation mechanism 320. When the determination receiver 313 has received the determination operation representing that the error has occurred, information representing that the error has occurred is replied to the server device 200.
Further, when the determination receiver 313 has received the error information ER from the server device 200, the determination receiver 313 generates the information representing whether or not the cause of the error corresponding to the error information ER has successfully been identified based on the operation from the user. In other words, when the error information ER has been received from the server device 200, the user analyzes the cause of the error corresponding to the error information ER based on, for example, the second operation log PL2. Then, the user inputs the operation representing whether or not the cause of the error has successfully been identified to the third operation mechanism 320.
The information representing whether or not the cause of the error has successfully been identified includes the identification information YS and the identification-failure information NS.
