  FIG. 6 is a block diagram illustrating an example of functions of the control unit included in the MFP according to the first embodiment, together with information stored in the storage unit. As illustrated in FIG. 6, the control unit 201 includes an operation reception unit 221 that receives a user operation, a calibration detection unit (operation end detection unit) 223, an extraction unit (extraction unit) 225, and a collation unit (collation) Means) 227, an authentication information receiving unit 229 (first communication control unit, second communication control unit), a display control unit (display control unit) 231, and an image formation control unit (image formation control unit) 241. .

  Storage unit (second storage unit) 202 is a storage unit that stores various types of information of MFP 100, and stores second authentication information 251. The second authentication information 251 is authentication information (emission right authentication information, summary information) of the toner cartridge 98 that is compatible with the MFP 100, and the administrator of the MFP 100 properly acquires information registered in the server PCs 101 and 101A. It is updated by doing. Note that the administrator of the MFP 100 has an access right to the server PCs 101 and 101A, whereby the second authentication information 251 can be updated.

  The storage unit 202 stores the second authentication information, which is such summary information, in association with both pieces of information together with the first authentication information. The first authentication information is unique information that can identify the toner cartridge that is a consumable, and based on the first authentication information, the second authentication information given to the toner cartridge (consumable) is extracted. Can do. Here, the server PCs 101 and 101A register that the toner cartridge 98 has received the offset authentication, and the information registered by the server PCs 101 and 101A includes the first for identifying the toner cartridge 98. Authentication information and second authentication information 251 are included.

  Specifically, the first authentication information is at least one of a manufacturing number of the toner cartridge 98, a credit number assigned to the toner cartridge 98, and an offset authentication number. The production number is an identification number of the toner cartridge 98 attached at the time of production. The credit number is an identification number for identifying the credit that the toner cartridge 98 has. The offset authentication number is an identification number for identifying an offset given when the toner cartridge 98 is authenticated for offset by a third party organization (public organization).

  The second certification information includes the offset certification applicant name, consumables sales company name, offset amount / calculated emission amount, offset project name, offset purchase cost (donation), and information on the date on which the offset becomes invalid. . The offset authentication applicant name is information for identifying a person who applied for offset authentication. The consumable sales company name is information for identifying the sales company that sells the toner cartridge 98.

  The calibration detection unit 223 detects the start and end of calibration. In this embodiment, the calibration detection unit 223 detects the start of calibration when a signal output from the safety switch 99 changes from an off signal to an on signal after a consumable item such as the toner cartridge 98 is replaced. To do. Specifically, when the connection completion signal is input from the safety switch 99, it is determined that the calibration is started, and the calibration start signal is output to the extraction unit 225. Further, upon detecting the start of calibration, the calibration detection unit 223 determines that the calibration is completed after a predetermined time has elapsed from the time of detection, and outputs a calibration end signal to the display control unit 231. The predetermined elapsed time after the detection of communication possible by the connection detection unit (mounting detection means) 209a used to determine the end of calibration is a value determined by the time required for calibration.

  Note that the calibration end may be detected by the calibration detection unit 223 receiving a confirmation completion signal from each unit for which an operation check or the like is performed in the calibration.

  As described above, the replacement of consumables such as the toner cartridge 98 is performed with the open / close door opened, and the open / close door is closed when the replacement is completed. This is because the calibration is started. Therefore, it is possible to detect the start of calibration at the timing when the open / close door is closed during consumable replacement.

  In addition, the calibration detection unit 223 can be configured to detect the start of calibration, for example, by detecting that the connection detection unit 209a can communicate with the storage unit 150 included in the toner cartridge 98. This is because, as described above, calibration is performed when a consumable such as the toner cartridge 98 is replaced.

  In response to detection of the start of calibration by the calibration detection unit 223, the extraction unit 225 accesses the storage unit 150 included in the toner cartridge 98 and determines whether or not authentication information that can be extracted is stored. If the authentication information that can be extracted is stored in the storage unit 150, the authentication information is extracted from the storage unit 150. If not, the authentication information that can be extracted is output to the display control unit 231. Here, since the first authentication information (unique information) is stored in the storage unit 150, the extraction unit 225 outputs the first authentication information extracted from the storage unit 150 to the collation unit 227 and the display control unit 231. To do.

  The collation unit 227 collates the first authentication information extracted from the storage unit 150 by the extraction unit 225. The collation unit 227 extracts the second authentication information 251 associated with the matching first authentication information when the first authentication information that matches the extracted first authentication information exists in the storage unit 202. Therefore, the second authentication information 251 extracted from the storage unit 202 by the collation unit 227 is authentication information of the toner cartridge 98 that is compatible with the MFP 100 registered in the server PCs 101 and 101A. Accordingly, the collation unit 227 can determine whether or not the toner cartridge 98 is a genuine product suitable for image formation by the MFP 100. The collation unit 227 determines that the toner cartridge 98 mounted on the MFP 100 is a genuine product that is suitable for image formation by the MFP 100 if there is matching information. Judged to be genuine. The collation unit 227 outputs the determined result to the display control unit 231 as the collation result. Further, the collation unit 227 outputs a collating signal indicating that the first authentication information and the second authentication information 251 are being collated to the display control unit 231.

  The extracted first authentication information is only m pieces of information (for example, item: serial number), and the first authentication information stored in the storage unit 202 is n pieces (n> m) of information. In the case of (for example, three items: a manufacturing number, a credit number, and an offset authentication number), one or more pieces of information (items) may be matched.

  The authentication information receiving unit 229 receives the third authentication information from either the server PC 101 or 101A. The third authentication information (detailed information) is authentication information of the toner cartridge 98, and includes information that makes the contents of the discharge right granted more detailed than the second authentication information 251. In the present embodiment, the detailed information of the second authentication information 251 includes at least information that describes the mechanism of the offset. In addition, the carbon offset attribution destination, the offset calculation emission amount, the credit type, and the carbon offset Including mark (registered trademark). The third certification information may further include information on promotion of greenhouse gas reduction efforts, explanation of guidelines based on offset / calculated emissions, outline of the project, offset target period, etc. .

  When the user operates the operation unit 53 and the operation receiving unit 221 receives an acquisition instruction for acquiring the third authentication information, the authentication information receiving unit 229 causes the data communication control unit 206 to be connected to one of the server PCs 101 and 101A. A transmission request for the third authentication information is transmitted. The server that has received the third authentication information transmission request among the server PCs 101 and 101A transmits the third authentication information to the MFP 100, and the data communication control unit 206 outputs the third authentication information to the authentication information receiving unit 229. The authentication information receiving unit 229 outputs the third authentication information input from the data communication control unit 206 to the display control unit 231 and stores the third authentication information in the storage unit 202 as the third authentication information 255.

  The display control unit 231 controls the display unit 51 and displays various types of information. The display control unit 231 includes a first offset credit authentication screen generation unit 233, a second offset credit authentication screen generation unit 235, and a message screen generation unit 237.

  When the verification unit 227 determines that the first offset credit authentication screen generation unit 233 is a genuine product, the first offset credit authentication screen generation unit 233 stores the second authentication information 251 stored in the storage unit 202 or the second authentication information stored in the storage unit 202. Using the authentication information 251 and the first authentication information extracted from the toner cartridge 98, a first offset credit authentication screen (see FIG. 7) is generated.

  The second offset credit authentication screen generation unit 235 generates a second offset credit authentication screen (see FIG. 8) based on the third authentication information corresponding to the specified toner cartridge 98 received by the authentication information receiving unit 229. To do. When the third authentication information is input from the authentication information receiving unit 229 and the display instruction of the third authentication information is input from the operation receiving unit 221, the second offset credit authentication screen generation unit 235 receives the input third authentication information. A second offset credit authentication screen including is generated.

  The first and second offset credit authentication screens may further include operation standby information. The operation standby information is information prompting the user to wait for an operation. For example, a first operation standby message (see FIG. 7) of “Adjusting the image quality of the image forming apparatus. "Please wait for a while. Detailed carbon offset certification information is displayed on the next page" and the second operation waiting message (see Fig. 8).

  The display control unit 231 causes the display unit 51 to display the first offset credit authentication screen generated by the first offset credit authentication screen generation unit 233 including the first operation standby message. The display control unit 231 switches the screen being displayed on the display unit 51 to a standby screen (standby screen) on condition that the calibration detection unit 223 detects the end of calibration. The standby screen is a screen for accepting a plurality of processes that can be executed by MFP 100.

  As described above, the display of the first offset credit authentication screen by the display control unit 231 is during calibration from the start to the end of calibration. For this reason, the specific information regarding the carbon offset of the consumable can be displayed at a timing that does not hinder the user's operation. In addition, it is possible to easily make a user who waits for calibration visually recognize that the manufacturer is a consumable manufacturer working on reducing greenhouse gases. Furthermore, it is possible to prove to the user who views the first offset credit authentication screen that the toner cartridge 98 is a consumable item with a credit. Furthermore, since it can be confirmed on the first offset credit authentication screen that the credit purchase cost is properly used, it is possible to prove to the user that the credit purchase cost of the toner cartridge 98 is not useless. Further improvement of the user's environmental motivation can be promoted.

  The first offset credit authentication screen may be displayed on condition that the setting for displaying the screen is made in advance. In addition, the first offset credit authentication screen generation unit 233 may store the generated first offset credit authentication screen in the storage unit 202 when a predetermined instruction is given by the operation reception unit 221. In this case, the display of the first offset credit authentication screen may be terminated, and the first offset credit authentication screen may be displayed according to a user instruction after the calibration is completed. The predetermined instruction is, for example, a copy instruction, a fax / image transmission instruction, a mail transmission instruction, a document filing process, or the like. In this embodiment, when these instructions are made during calibration, they are accepted as reservations, and processing is performed after the calibration is completed. Note that the fax / image transmission and mail transmission processes do not use the image forming unit 209, and therefore may be configured to perform the processes during calibration.

  The display control unit 231 causes the display unit 51 to display the second offset credit authentication screen that is generated by the second offset credit authentication screen generation unit 235 and includes the second operation standby message. The second offset credit authentication screen is a screen that is displayed after the first offset credit authentication screen is displayed. The second offset credit authentication screen is displayed on the condition that an instruction to acquire third authentication information is displayed during the display of the first offset credit authentication screen.

  Further, the display control unit 231 displays the screen (first or second offset credit authentication screen) being displayed on the display unit 51 on the condition that the calibration detection unit 223 detects the end of calibration. Switch to.

  As described above, since the display of the second offset credit authentication screen by the display control unit 231 is being calibrated, it is easy for the user waiting for calibration to be a consumable manufacturer working on greenhouse gas reduction. It can be visually recognized. Further, since the second offset credit authentication screen includes the third authentication information, the information about the carbon offset of the consumable can be displayed in more detail than the second authentication information 251.

  Note that the second offset credit authentication screen generation unit 235 displays the generated second offset credit authentication screen in the same manner as the first offset credit authentication screen when the operation receiving unit 221 receives a predetermined instruction similar to the above. You may make it memorize | store in the memory | storage part 202. FIG. In this case, the display of the second offset credit authentication screen may be terminated, and the second offset credit authentication screen may be displayed according to a user instruction after the calibration is completed.

Note that the message screen generation unit 237 generates a message screen (not shown) indicating that the toner cartridge is incompatible when no connection completion signal is input from the connection detection unit 209a.

  When one of the first and second confirmation screens, the warning screen, and the error screen is generated by the message screen generation unit 237, the display control unit 231 displays the generated screen on the display unit 51 (see FIG. 5). The display of the warning screen allows the user to recognize that the mounted toner cartridge is a non-genuine product, and can therefore be used to prevent malfunction of the image forming apparatus due to a non-genuine product. In addition, when the second confirmation screen is generated by the message screen generation unit 237 while the first confirmation screen is displayed, the display control unit 231 switches the screen to be displayed on the display unit 51 to the second confirmation screen.

  FIG. 9 is a diagram illustrating an example of the first and second confirmation screens. FIG. 9A is a diagram illustrating an example of the first confirmation screen, and FIG. 9B is a diagram illustrating an example of the second confirmation screen. Further, the first confirmation screen 430 displays a message “Please wait for a while. Checking for replaced consumables” when the toner cartridge 98 as a consumable is mounted on the MFP 100 and the opening / closing door is closed. Is displayed. Then, when the verification of the first authentication information stored in the storage unit 150 provided in the toner cartridge 98 is started, the screen is switched to the second confirmation screen including the message “Please wait for a while. Consumable information is being checked.” Change.

  The image formation control unit 241 controls the image formation unit 209 to form an image on a sheet. Specifically, the image formation is performed on an image of a screen displayed by the display control unit 231 or image data generated by reading a document placed on a document table. However, when a print instruction (copy instruction) is input from the operation reception unit 221 during calibration, the image formation control unit 241 receives a print reservation and forms an image after the calibration is completed. The screen displayed by the display control unit 231 includes first and second offset credit authentication screens 300 and 400. When the user presses the copy reservation start button 305 in a state where one of the first and second offset credit authentication screens 300 and 400 is displayed, the image formation control unit 241 displays the authentication information included in the displayed screen. Schedule printing. In addition, when the user presses the copy button 305 in a state where one of the first and second offset credit authentication screens 300 and 400 is displayed, the image formation control unit 241 reads the document placed on the document table. The image formation of the image data generated by the above is reserved. The formation of the image of the image data generated by reading the document placed on the document table is not limited to the state in which one of the first and second offset credit authentication screens 300 and 400 is displayed. Absent.

  Here, the image for which the print reservation has been received is formed in the image forming unit 209 after the calibration is completed, but the processing performed after the calibration is completed is not limited to this. For example, processing such as mail transmission, copy or fax transmission may be executed. In this case, the operation reception unit 221 may monitor the start and end of calibration, and output a process execution instruction to each unit responsible for mail transmission, copying, and fax transmission after the calibration is completed.

  FIG. 10 is a flowchart illustrating an example of a flow of activation control processing at the time of consumable replacement. The activation control process is a process executed by the control unit 201 when the control unit 201 (see FIG. 4) executes an activation control program stored in the ROM or the HDD. As shown in FIG. 10, the control unit 201 determines whether or not the safety switch 99 is turned on (step S01). Specifically, it is determined whether a signal from the safety switch 99 input to the control unit 201 has changed from an off signal to an on signal. If the signal has changed from the off signal to the on signal, the process proceeds to step S02. The activation control process is a process executed when the safety switch 99 changes from OFF to ON, in other words, when the open / close door changes from an open state to a closed state. As described above, it may be configured to determine whether the signal input from the connection detection unit 209a to the control unit 201 has changed from the non-connection detection signal to the connection detection signal.

  In the next step S02, calibration is started. Then, it is determined whether or not an error has been detected (step S03). If an error is detected, the process proceeds to step S04. If not, the process proceeds to step S05.

  In the next step S04, calibration is stopped, an error screen including an error message is displayed, and the start control process is terminated. The error message is, for example, a message “An error has occurred in the image forming apparatus. Please contact a service person”.

  In step S05, it is determined whether calibration is completed. If calibration is complete, the process proceeds to step S06; otherwise, the process returns to step S03.

  In step S06, it is determined whether or not there is a print reservation reception for printing at least one of the first and second offset credit authentication screens 300 and 400. If there is a print reservation acceptance, the process proceeds to step S7; otherwise, the process proceeds to step S08.

  In step S07, printing of a screen for which a print reservation is accepted is executed out of first and second offset credit authentication screens 300 and 400, and the process proceeds to step S08.

  In step S08, it is determined whether there is a predetermined instruction reservation reception. The predetermined instruction reservation reception specifically includes a copy reservation reception, a fax / image transmission reservation reception, a document filing reservation reception, and the like. If there is a predetermined instruction reservation acceptance, the process proceeds to step S09; otherwise, the activation control process is terminated.

  In step S09, a process for which a predetermined instruction reservation is accepted is executed, and the activation control process is terminated. In the flowchart of FIG. 10, the authentication information is printed (S06, S07) prior to the execution of the process reserved on the first and second offset credit authentication screens 300, 400 (S08, S09). Prior to the printing of the authentication information, the reserved processing may be executed on the first and second offset credit authentication screens 300 and 400.

  FIG. 11 is a flowchart showing an exemplary flow of authentication information display / reservation acceptance processing. The authentication information display / reservation reception process is a process executed by the control unit 201 when the control unit 201 executes an authentication information display / reservation reception program stored in the ROM or HDD. As shown in FIG. 11, when the toner cartridge 98 is set, the control unit 201 generates a first confirmation screen 430 and displays the generated first confirmation screen 430 (step S21).

  In step S22, it is determined whether the start of calibration is detected. Specifically, it is determined whether or not the safety switch 99 has changed from an off signal to an on signal. If safety switch 99 changes from the off signal to the on signal, the process proceeds to step S23. That is, the authentication information display / reservation acceptance process is a process that is executed by detecting the start of calibration, and is executed in parallel with the activation control process shown in FIG. That is, the processing from step S23 is executed by starting calibration in step S03 shown in FIG. However, if an error is detected in step S04 shown in FIG. 10, the control unit 201 interrupts the authentication information display / reservation acceptance process.

  In step S23, the first authentication information stored in the storage unit 150 included in the toner cartridge 98 is extracted, and the extracted first authentication information is collated (step S24). At this time, the display is switched from the first confirmation screen 430 to the second confirmation screen 440.

  In the next step S25, it is determined whether or not it is a genuine consumable. Specifically, if the first authentication information that matches the extracted first authentication information exists in the storage unit 202, it is determined as a genuine consumable, and the process proceeds to step S27. And the process proceeds to step S26.

  In step S <b> 26, a warning screen is generated and the generated warning screen is displayed on the display unit 51. The warning screen is, for example, a screen including a message “This is a non-genuine consumable and may cause trouble in the image forming apparatus.” Since the warning screen is displayed when it is determined that the mounted consumable is not a genuine consumable, the user who views the warning screen can be prompted to use the genuine consumable. Thereby, it is possible to prevent malfunction of the image forming apparatus due to the use of non-genuine consumables.

  In the next step S27, it is determined whether or not there is a display setting for the second authentication information 251. If there is a display setting for second authentication information 251, the process proceeds to step S30. If not, the process proceeds to step S28.

  In step S28, the first operation standby message is displayed on display unit 51, and the process proceeds to step S29. The first operation standby message is, for example, a message “Adjusting the image quality of the image forming apparatus. Please wait for a while”.

  In step S29, it is determined whether the calibration time has elapsed. Specifically, it is determined whether or not a predetermined time has elapsed since the start of calibration in step S22. If a predetermined time has elapsed from the detection of the start of calibration, the process proceeds to step S45, the screen display is switched to the standby screen (standby screen), and the authentication information display / reservation acceptance process is terminated.

  In step S30, the first offset credit authentication screen 300 is generated based on the first authentication information extracted in step S23 and the second authentication information 251 stored in the storage unit 202, and the generated second offset is generated. A credit authentication screen 400 is displayed on the display unit 51.

  In the next step S31, it is determined whether or not there is a print instruction. Specifically, it is determined whether or not the copy reservation start button 303 is pressed on the first offset credit authentication screen 300 displayed in step S30. If copy reservation start button 303 is pressed, the process proceeds to step S32. If not, the process proceeds to step S33.

  In step S32, the print instruction in step S31 is accepted as a print reservation, and the process proceeds to step S33.

  In step S33, it is determined whether or not a predetermined instruction has been given. Specifically, it is determined whether any of the copy button 305, the fax / image transmission button 307, or the document filing button 309 is pressed on the first offset credit authentication screen 300 displayed in step S30. If any of copy button 305, fax / image transmission button 307, or document filing button 309 is pressed, the process proceeds to step S34; otherwise, the process proceeds to step S35.

  In step S34, a reservation for a predetermined instruction in step S33 is accepted, and the process proceeds to step S35. If a fax / image transmission instruction or mail transmission instruction is accepted in step S33, the accepted instruction may be executed.

  Although not shown in the flowchart of FIG. 11, when printing or a reservation for a predetermined instruction is accepted in steps S32 and S34, the displayed first offset credit authentication screen 300 is once deleted. The screen is shifted to a screen for inputting specific processing conditions such as printing or a predetermined instruction. When the input of specific processing conditions is completed, the first offset credit authentication screen 300 is displayed again. .

  In step S35, it is determined whether the calibration time has elapsed. Specifically, it is determined whether or not a predetermined time has elapsed since the start of calibration in step S22. If a predetermined time has elapsed since the detection of the start of calibration, the process proceeds to step S45, the screen display is switched to the standby screen (standby screen), and the authentication information display / reservation acceptance process is terminated. Advances to step S36.

  In step S36, it is determined whether or not the icon 301 on the first offset credit authentication screen 300 displayed in step S30 has been pressed. If icon 301 is pressed, the process proceeds to step S37; otherwise, the process returns to step S31. If a print instruction has already been given in step S31, steps S31 and 33 may be skipped.

  In step S37, the server PC 101 or 101A is requested to transmit the third authentication information. Then, it is determined whether or not the third authentication information has been received (step S38). Specifically, it is determined whether or not the third authentication information transmitted by the server that has received the third authentication information transmission request among the server PCs 101 and 101A is received via the data communication control unit 206. If the third authentication information is received, the process proceeds to step S39.

  In step S39, the second offset credit authentication screen 400 is generated based on the third authentication information received in step S38, and the generated second offset credit authentication screen 400 is displayed on the display unit 51.

  In the next step S40, it is determined whether or not there is a print instruction. Specifically, it is determined whether or not the copy reservation start button 303 is pressed on the second offset credit authentication screen 400 displayed in step S39. If copy reservation start button 303 is pressed, the process proceeds to step S41; otherwise, the process proceeds to step S42.

  In step S41, the print instruction in step S40 is accepted as a print reservation, and the process proceeds to step S42.

  In step S42, it is determined whether or not a predetermined instruction has been given. Specifically, it is determined whether or not the copy reservation start button 303 is pressed on the second offset credit authentication screen 400 displayed in step S39. If copy reservation start button 303 is pressed, the process proceeds to step S43; otherwise, the process proceeds to step S44.

  In step S43, a reservation for a predetermined instruction in step S42 is accepted, and the process proceeds to step S44.

  In this case as well, in step S41 and step S43, when printing or a reservation for a predetermined instruction is accepted, the displayed second offset credit authentication screen 400 is temporarily deleted, etc. When the screen transitions to a screen for inputting a specific processing condition of a predetermined instruction and the input of the specific processing condition is completed, the second offset credit authentication screen 400 is displayed again.

  In step S44, it is determined whether the calibration time has elapsed. Specifically, it is determined whether or not a predetermined time has elapsed since the start of calibration in step S22. If a predetermined time has elapsed from the detection of the start of calibration, the process proceeds to step S45. If not, the process returns to step S41.

  In step S45, the screen display is switched to a standby screen (standby screen), and the authentication information display / reservation acceptance process is terminated.

  As described above, the authentication information display / reservation acceptance process ends when it is determined that the calibration time in steps S29, S35, and S44 has elapsed. That is, the authentication information display / reservation acceptance process is a process that ends when it is determined that the calibration is completed in step S05 of the activation control process shown in FIG. For this reason, the activation control process shown in FIG. 10 is continuously executed after the authentication information display / reservation acceptance process is completed. The processes after step S06 of the activation control process are processes executed based on the authentication information display / reservation acceptance process. The process of step S07 is executed when a print reservation is accepted in steps S32 and S41, and the process of step S09 is executed when a predetermined instruction reservation is accepted in steps S34 and S43.

  As described above, the MFP 100 according to the present invention is an image forming apparatus to which a toner cartridge to which an exchangeable greenhouse gas emission right is given is mounted. The extraction unit 225 for extracting the first authentication information and the second authentication information 251 including the specific contents of the greenhouse gas emission right assigned to the toner cartridge 98 associated with the extracted first authentication information. And a display control unit 231 that is included in the one-offset credit authentication screen 300 and is displayed on the display unit 51.

  Accordingly, the first content including the specific contents of the greenhouse gas emission rights assigned to the toner cartridge 98 associated with the first authentication information extracted from the storage unit 150 provided in the toner cartridge 98 mounted on the MFP 100. 2 authentication information 251 is included in the first offset credit authentication screen 300 and displayed. For this reason, the user can confirm on the first offset credit authentication screen 300 that the attached toner cartridge 98 is authorized to emit greenhouse gases. In addition, the user viewing the first offset credit authentication screen 300 can know the specific contents of greenhouse gas emission rights. Therefore, when the user purchases the toner cartridge 98 to which the greenhouse gas emission right is given, it is possible to easily know more specific contents regarding the purchased greenhouse gas emission right as a result.

  In addition, it is not currently conceivable for a manufacturer / seller who manufactures / sells an irregular toner cartridge to apply for a greenhouse gas emission right for the irregular toner cartridge. Therefore, it can be determined whether or not it is a genuine product based on whether or not the emission certification information is displayed. As described above, when the emission certification information cannot be displayed, a message notifying that the product is a non-genuine product is displayed. By displaying, it is possible to prevent malfunction of the MFP 100 due to the use of an unauthorized product.

  Further, the MFP 100 of the present invention is an image forming apparatus to which a toner cartridge to which an exchangeable greenhouse gas emission right is given is attached, and the first authentication information from the storage unit 150 provided in the attached toner cartridge 98. And the third authentication information 253 including the specific content of the greenhouse gas emission right assigned to the toner cartridge 98 associated with the extracted first authentication information. And a display control unit 231 that is included in the authentication screen 400 and displayed on the display unit 51.

Accordingly, the first content including the specific contents of the greenhouse gas emission rights assigned to the toner cartridge 98 associated with the first authentication information extracted from the storage unit 150 provided in the toner cartridge 98 mounted on the MFP 100. 3 authentication information 253 is included in the second offset credit authentication screen 400 and displayed. For this reason, the user can confirm on the first offset credit authentication screen 300 that the attached toner cartridge 98 is authorized to emit greenhouse gases. In addition, the user viewing the first offset credit authentication screen 300 can know the specific contents of greenhouse gas emission rights. Therefore, when the user purchases the toner cartridge 98 to which the greenhouse gas emission right is given, it is possible to easily know more specific contents regarding the purchased greenhouse gas emission right as a result. In addition, since the second offset credit authentication screen 400 includes more detailed information on greenhouse gas emission rights than the first offset credit authentication screen 300, the user can learn about greenhouse gas emission rights, and has an environmental motivation. Can be improved.
<Second Embodiment>
The MFP 100 according to the first embodiment displays the first offset credit authentication screen 300 or the second offset credit authentication screen 400 during calibration. When the preview display instruction is given while the first offset credit authentication screen 300 or the second offset credit authentication screen 400 is displayed, the MFP 100 according to the second embodiment displays the first offset credit authentication screen 300 or 400. In the middle screen, the second authentication information or the third authentication information displayed in the information display area 311 is preview-displayed.

  FIG. 12 is a block diagram illustrating an example of functions of the control unit included in the MFP according to the second embodiment, together with information stored in the storage unit. The control unit 201A is different from the control unit 201 illustrated in FIG. 6 in that the operation reception unit 221 is changed to the operation reception unit 221A and the display control unit 231 is changed to the display control unit 231A. The other configuration is the same as the configuration shown in FIG. 6, and therefore description thereof will not be repeated here.

  The operation reception unit 221A includes a preview display instruction reception unit 245. The preview display instruction accepting unit 245 accepts a preview display instruction when the user presses a preview display button provided in the operation unit 53. The operation reception unit 221A outputs the received preview display instruction to the display control unit 231A.

  The display control unit 231A includes a preview screen generation unit 243. The preview screen generation unit 243 generates a preview screen based on the first to third authentication information. The preview screen is generated corresponding to the screen being displayed in a state where any one of the first and second offset credit authentication screens 300 and 400 is displayed by the display control unit 231A. The display control unit 231A causes the display unit 51 to display the preview screen generated by the preview screen generation unit 243. Note that the preview screen may further include operation standby information.

  The preview screen includes a first preview screen and a second preview screen. When the preview display instruction receiving unit 245 receives a preview display instruction during display of the first offset credit authentication screen 300, the preview screen generating unit 243 generates a first preview screen including the first and second authentication information. To do. The first and second authentication information included in the first preview screen generated by the preview screen generation unit 243 is displayed as a preview image smaller than the screen size. For this reason, the user who sees the preview image can confirm the mode after printing before the image formation.

  When the preview display instruction receiving unit 245 receives a preview display instruction while the second offset credit authentication screen 400 is displayed, the preview screen generating unit 243 generates a second preview screen including the third authentication information. The third authentication information included in the second preview screen generated by the preview screen generation unit 243 is displayed as a preview image smaller than the screen size. For this reason, the user who sees the preview image can confirm the mode after printing before the image formation. Here, the third authentication information is information of a plurality of pages. For example, when the third authentication information is an even number page, the odd numbered page and the even numbered page of the third authentication information are displayed on one page for every two pages on the second preview screen. As a result, the user viewing the second preview screen can confirm the third authentication information in a spread state.

  Note that the second offset credit authentication screen generation unit 235 may switch to a predetermined message when there is a predetermined instruction from the operation reception unit 221A during the display of the second preview screen. In this case, the third authentication information received by the authentication information receiving unit 229 may be stored in the storage unit 202, and the second preview screen may be displayed again after processing corresponding to a predetermined instruction. The predetermined message is an instruction acceptance message indicating that a predetermined instruction has been accepted. Specifically, the predetermined instruction is a copy instruction, a fax / image instruction, a mail transmission instruction, or the like.

  FIG. 13 is a diagram illustrating an example of the first preview screen. As shown in FIG. 13, the first preview screen 450 includes an information display area 311, various button display areas around the information display area 311, and a preview image 451. A preview image 451 is displayed in the information display area 311. The preview image 451 is an image that includes the first and second authentication information and is smaller than the size of the information display area 311.

  The various buttons displayed in the various display areas include at least an icon 301, a copy reservation start button 303, a copy button 305, a fax / image transmission button 307, and a document filing button 309. When the user presses the copy reservation start button 303, an image in the same mode as the preview image 451 is formed. Thereby, the paper data printed in the mode desired by the user can be obtained.

  Further, when the user presses the icon 301, the third authentication information is acquired, and the second offset credit authentication screen 400 generated based on the acquired third authentication information is displayed. Various instructions can be input by pressing the copy button 305, the fax / image transmission button 307, or the document filing button 309.

  FIG. 14 is a diagram illustrating an example of the second preview screen. As shown in FIG. 14, the second preview screen 500 includes an information display area 311 and various button display areas around the information display area 311. A preview image 511 is displayed in the information display area 311. The preview image 511 is an image that includes the third authentication information 253 and is smaller than the size of the information display area 311. Here, the third authentication information 253 is information of a plurality of pages, and the first page and the second page of the third authentication information 253 are shown in the preview image 511. Here, although the preview image 511 is shown as an image including two pages, it may include four pages or more pages. Further, how many pages the preview image 511 includes may be switchable by the user.

  The various buttons displayed in the various button display areas include at least a copy reservation start button 303, a copy button 305, a fax / image transmission button 307, and a document filing button 309. When the user presses the copy reservation start button 303, an image having the same form as the preview image 511 is formed. Thereby, the paper data printed in the mode desired by the user can be obtained.

  FIG. 15 is a flowchart showing an example of the flow of the first preview display / reservation acceptance process. The first preview display / reservation acceptance process is a process executed by the control unit 201A when the control unit 201A executes the first preview display / reservation acceptance program stored in the ROM or HDD. As shown in FIG. 15, the control unit 201A displays the first offset credit authentication screen 300 (step S51). Then, a preview display instruction is accepted (step S52), a first preview screen 450 is generated, and the generated first preview screen 450 is displayed on the display unit 51 (step S53). That is, the processing from step S53 is executed when a preview display instruction is accepted in step S31 shown in FIG.

  In the next step S54, it is determined whether or not there is a print instruction. Specifically, it is determined whether or not the copy reservation start button 303 is pressed on the first preview screen 450 displayed in step S53. If copy reservation start button 303 is pressed, the process proceeds to step S55; otherwise, the process proceeds to step S56.

  In step S55, the print instruction in step S54 is accepted as a print reservation, and the process proceeds to step S56.

  In step S56, it is determined whether or not a predetermined instruction has been given. Specifically, it is determined whether any of the copy button 305, the fax / image transmission button 307, or the document filing button 309 is pressed on the first offset credit authentication screen 300 displayed in step S30. If either fax / image transmission button 307 or document filing button 309 is pressed, the process proceeds to step S57; otherwise, the process proceeds to step S60.

  In step S57, an instruction acceptance message is displayed. The instruction reception message is a message corresponding to the processing instruction received in step S56. For example, the instruction acceptance message is a message “Copy accepted”.

  In step S58, a reservation for a predetermined instruction in step S56 is accepted. Then, the display of the instruction acceptance message displayed in step S57 is terminated (step S59).

  In the next step S60, it is determined whether or not the calibration time has elapsed. Specifically, it is determined whether or not a predetermined time has elapsed since the start of calibration in step S22. If a predetermined time has elapsed from the detection of the start of calibration, the first preview display / reservation acceptance process ends. If not, the process returns to step S53.

  As described above, the first preview display / reservation acceptance process ends when it is determined that the calibration time in step S60 has elapsed. That is, the authentication information display / reservation acceptance process is a process that ends when it is determined that the calibration is completed in step S05 of the activation control process shown in FIG. For this reason, the activation control process shown in FIG. 10 is continuously executed after the authentication information display / reservation acceptance process is completed. The processes after step S06 of the activation control process are processes executed based on the authentication information display / reservation acceptance process. The process of step S07 is executed when a print reservation is accepted in step S55, and the process of step S09 is executed when a predetermined instruction reservation is accepted in step S58.

  FIG. 16 is a flowchart showing an exemplary flow of the second preview display / reservation acceptance process. The second preview display / reservation acceptance process is a process executed by the control unit 201A when the control unit 201A executes the second preview display / reservation acceptance program stored in the ROM or HDD. The second preview display / reservation acceptance process is different from the first preview display / reservation acceptance process shown in FIG. 15 in that steps S51 and S53 are changed to steps S51A and 53A and steps S71 and S72 are added. It is. Since the other processes are the same as the first preview display / reservation acceptance process shown in FIG. 15, differences from the first preview display / reservation acceptance process shown in FIG. 15 will be mainly described here.

  In step S51A, second offset credit authentication screen 400 is displayed. Then, a preview display instruction is accepted (step S52), a second preview screen 500 is generated, and the generated second preview screen 500 is displayed on the display unit 51 (step S53A). That is, the processing from step S53A is executed when a preview display instruction is accepted in step S40 shown in FIG.

  In step S71, it is determined whether or not the third authentication information received in step S39 is stored in storage unit 202. If the third authentication information is stored in storage unit 202, the process proceeds to step S58; otherwise, the process proceeds to step S72.

  In step S72, the third authentication information received in step S39 is stored in storage unit 202, and the process proceeds to step S58.

  The MFP 100 according to the second embodiment displays the second preview screen 500 on condition that the preview display instruction during the display of the second offset credit authentication screen 400 is received, and displays a predetermined instruction during the display of the second preview screen 500. The third authentication information is stored in the storage unit 202 on the condition of acceptance. The MFP 100 is configured to display a third authentication information display button for instructing the operation unit 53 to display the third authentication information on the initial screen on condition that the third authentication information is stored in the storage unit 202. Furthermore, you may provide. In this case, the third authentication information can be directly browsed without going through the first offset credit authentication screen 300 by a simple operation in which the user presses the third authentication information display button. Thereby, the detailed information regarding the carbon offset of a consumable can be freely browsed regardless of timing.

  In the first embodiment and the second embodiment, the MFP 100 verifies the first authentication information extracted from the storage unit 150, but the first authentication information is based on the information registered in the server PCs 101 and 101A. You may make it collate authentication information. In this case, the MFP 100 transmits the first authentication information extracted from the storage unit 150 included in the toner cartridge 98 to one of the server PCs 101 and 101A, and the server that has received the first authentication information receives the registered information and the first authentication information. And when there is one or more matching information, information unique to the toner cartridge 98 may be transmitted to the MFP 100 as the second authentication information. In this case, the storage capacity of the storage unit 202 of the MFP 100 can be small, and the collation unit 227 is unnecessary.
