Update the image forming supplies data. When this information (eg, data) causes the exemplary printer to update compatible imaging article data, this information (eg, data) may be considered signed data. As described herein, the signed data may be used by a security module and/or a printer to authenticate an imaging article and/or an imaging device compatible with an exemplary printer. It may contain a digital signature used to authenticate modifications to product data. In some examples, an indication (e.g., a flag) indicating the presence of signed data is stored on a first memory on the imaging article to update the exemplary printer compatible imaging article data. Other information is stored on the second memory on the imaging article, such as information (eg, data) that causes

In some examples, when an imaging article containing signed data (e.g., an authenticated imaging article) is inserted and/or coupled to an exemplary printer, the printer identifies the exemplary imaging article as Communicate to retrieve, access, and/or retrieve information (eg, data) stored on the inserted imaging article to update compatible imaging article data. In some examples, the information (e.g., data) stored on the authenticated imaging article tells the printer to add at least one imaging article to the compatible imaging article data stored by the printer. Let The added imaging article identifier may be the same as the imaging article identifier of the inserted imaging article, or it may be different (e.g., the first imaging article is the same as the imaging article identifier of the second imaging article). and the first imaging article may be the same as the second imaging article). That is, if an inserted imaging article contains signed data, the inserted imaging article that was previously not on the list may add itself to the list. In some instances, if the added imaging article is different from the inserted imaging article, the added imaging article is a different part number than the inserted imaging article. different imaging article identifier than the imaging article identifier of the imaging article, different yield than the inserted imaging article, different color than the inserted imaging article, different volume than the inserted imaging article , a different chemistry than the inserted imaging article, a different size than the inserted imaging article, and/or the like.

As described herein, unsigned data may not include a security module and/or a digital signature that authenticates the imaging article. In some instances, an imaging article containing unsigned data is not authorized to modify compatible imaging article data stored on the printer. However, while those imaging articles containing unsigned data may not be authorized to modify compatible imaging article data, according to the exemplary printer disclosed herein: Those imaging articles containing unsigned data may be facilitated by the exemplary printer and/or those imaging articles containing unsigned data may facilitate the exemplary printer's imaging. It may be easier to dynamically define how to interact with supplies. In some examples, when an imaging article containing unsigned data is inserted and/or coupled to an exemplary printer, the exemplary printer may request authorization ( user's permission).

Update quality control data. In some examples, the consumable management data relates to the print yield and/or number of pages that an inserted imaging article can print during its useful life. In some such examples, the printable volume data stored on the inserted imaging article is used by the printer to create consumable gauges and/or consumable tracking information. The consumable gauge and/or consumable tracking information can be displayed to the user and/or used by the printer in conjunction with a life tracking process stored on the printer. In some examples, a first memory on the imaging article stores an indication of the presence of signed data and/or unsigned data, and a second memory on the imaging article stores an indication of the presence of signed data and/or unsigned data. Other information (eg, data) is stored, such as information (eg, data) that allows the printer to dynamically define how the printer interacts with an inserted imaging article.

In some examples, the data stored in the second memory on the imaging article relates to color management data. In some examples, the color management data is used by the printer to supply a specific amount of feed material and/or a specific combination of feed materials (e.g., cyan feed material and yellow feed material) to the imaging article. Apply or develop to render the desired color. In some examples, the color management data is used by the printer to cause various components of the printer and/or various components of the inserted imaging article to function in a particular manner. For example, in some examples, imaging article data is used by a printer to heat a fuser of the printer to a threshold temperature and/or to heat the fuser to a threshold temperature within a given time frame. and/or such fuser has a certain temperature distribution and/or behavior.

In some examples, the first memory of the imaging article indicates that the second memory contains limited or no data (e.g., no signed data, contains an indication that there is no unsigned data). In such examples, the inserted imaging article does not include information (eg, data) that dynamically defines, for example, how the exemplary printer interacts with the inserted imaging article. For example, displaying consumable tracking information and/or a consumable gauge when using such imaging supplies, as such imaging supplies may not include consumable management data. may not be possible. In some such examples, when an imaging article containing no data is inserted into and/or coupled to an exemplary printer, the exemplary printer indicates that the printer will use the inserted imaging article. Permission (eg, user permission) may be obtained prior to doing so. In instances where there is no data on the imaging article, the printer uses default settings stored on the printer (e.g., for fuser temperature) when performing various processes with the inserted imaging article. default settings).

In some examples, if the first memory 122 contains a flag indicating that the second memory 124 contains signed data (e.g., authenticated data), then the executable code is executed by the exemplary processor 130 may cause processor 130 to delete at least one imaging article identifier from the compatible imaging article data stored on data storage device 126 when executed by a . In some examples, compatible imaging supplies data identifies and/or lists imaging supplies that can be used by and/or are compatible with printer 100 .

In some examples, if the first memory 122 contains a flag indicating that the second memory 124 contains signed data (e.g., authenticated data), then the executable code is executed by the exemplary processor 130 even if the imaging article 120 is not included in the compatible imaging article data and/or is not identified in the compatible imaging article data when executed by Processor 130 may facilitate using the imaging article 120 . For example, if the imaging article 120 is an imaging article supplied to a customer under a contract (e.g., an imaging article contract), the manufacturer of the printer 100 and/or the manufacturer of the imaging article 120 , the imaging article 120 is intended to be used by the printer 100 without including the imaging article 120 in the compatible imaging article data.

In some examples, first memory 122 indicates that second memory 124 contains signed data (eg, authenticated data) and/or unsigned data (eg, unauthenticated data). If flags are included, the executable code, when executed by the exemplary processor 130, causes the processor 130 to dynamically define how the printer 100 interacts with the imaging article 120; and/or It may facilitate dynamically defining consumable management data associated with imaging supplies 120 .

In some examples, where the executable code includes color management data, the executable code, when executed by the exemplary processor 130, directs the imaging article 120 to a specified amount of imaging material (e.g., ink, A desired color is rendered on substrate 106 by causing a supply of toner, etc.) to heat a component of printer 100 (e.g., fuser 118) to a threshold temperature and/or to heat the component (e.g., fuser 118) 118) is heated to a threshold temperature at a threshold rate and/or within a threshold timeframe.

In some examples, the first memory 122 includes a flag indicating that the second memory 124 contains limited or no data (eg, no color management data). In that case, the executable code, when executed by the exemplary processor 130, causes the processor 130 to: It may facilitate using the imaging article 120 in the default "safe" mode. In some examples where imaging article 120 contains limited data or no data, the executable code, when executed by exemplary processor 130, provides limited data to processor 130. Permission to use the data-only or non-data-containing imaging article 120 is prompted and/or received. In some instances, this authorization indicates that the user accepts the risks associated with using an imaging article 120 that contains limited or no data.

In some examples, when second memory 124 contains limited or no data, on imaging article 120, printer 100 communicates with imaging article 120. There may be no executable code that dynamically defines the method. In some examples, when second memory 124 contains limited or no data, processor 130 may use executable code stored on data storage device 126 to , which, when executed by the exemplary processor 130, causes the processor 130 to heat a component of the printer 100 (eg, the fuser 118) to a threshold default temperature and/or configure its configuration It may facilitate heating a component (eg, fuser 118) to a threshold default temperature at a threshold default speed and/or within a threshold default timeframe. In some examples, if the second memory 124 contains limited or no data (eg, no consumable management data), the printer 100 may, for example, display 110 and/or Or it may not be possible to display the consumables gauge on the display control panel 112 .

In this example, the machine-readable instructions include programs for execution by a processor, such as processor 130 and/or processor 512 shown in exemplary processor platform 500, described below in connection with FIG. The program is stored on a tangible computer readable storage medium such as a CD-ROM, floppy disk, hard disk, digital versatile disk (DVD), Blu-ray disk, or memory associated with the processor 130,512. Although it may be implemented in software, the entire program and/or various portions may alternatively be implemented by devices other than processors 130, 512, and/or may be implemented using firmware or dedicated hardware.

The program of FIG. 2 begins by the program identifying an imaging article in the printer (block 202). This may be done, for example, by inserting and/or coupling imaging article 120 into printer 100 and having controller 108 and/or processor 130 identify the presence of imaging article 120 . The program determines whether signed data exists on the imaging article 120 (block 204). For example, the processor 130 interacts with the exemplary imaging article 120 to obtain, access, and/or read instructions (eg, data) stored on the first memory 122, and the imaging article. This is done by determining whether 120 contains signed data stored on imaging article 120 . If signed data exists on imaging article 120, the program proceeds to the process disclosed in FIG. 3 (block 206). The instructions executed by printer 100 may be stored on first memory 122 , second memory 124 , third memory 125 and/or data storage device 126 .

On the other hand, if signed data is not present on the imaging article (eg, unsigned data), the program obtains the model type from the imaging article (block 208). This includes, for example, processor 130 interacting with exemplary imaging article 120 to obtain, access, and/or retrieve instructions stored on third memory 125, model type of imaging article 120, and/or by obtaining other identifiers (eg, imaging article identifiers). The obtained model type is compared to the model types allowed by the printer (block 210). This is done, for example, by processor 130 comparing the obtained model type and/or imaging article type with compatible imaging article data stored, for example, on data storage device 126 . The program determines whether the model type obtained is one of the model types allowed by the printer (block 212). This is done, for example, by processor 130 determining whether the retrieved model type and/or imaging article type is included in the compatible imaging article data. In some examples, if the model type obtained is not one of the model types allowed by the printer, the program prevents the printer from using the imaging article in the printing process (block 213). For example, processor 130 may prevent printer 100 from using imaging article 120 in the print process, and/or processor 130 may display an error message on display 110 and/or display control panel 112. done by

The program determines whether consumables management data is included on the imaging supplies (block 214). This may be accomplished, for example, by processor 130 interacting with exemplary imaging article 120 to obtain, access, and/or read information (e.g., data) stored on second memory 124 to form an image. This is done by determining whether the supplies 120 contain consumable management data. In some examples, the consumables management data relates to color management data, the printable volume of the imaging article 120, and/or the number of pages that the imaging article 120 can print during its useful life. ing.

If consumable management data exists on the imaging article, a notification is provided indicating the presence of unsigned consumable management data (block 216). This may be done, for example, by processor 130 to notify image source 104, display device 110, and/or display control panel 112 of the risks associated with using imaging article 120, for example, including unsigned data. It is done by letting The program determines whether it has received permission to use the unsigned consumable management data (block 218). For example, processor 130 and/or printer 100 may be authorized to interact with image source 104, display device 110, and/or display control panel 112 to use unsigned consumable management data. by receiving an input indicating that the

If permission to use the unsigned consumable management data has been obtained, the consumable management data is obtained from the imaging article (block 220). This may be accomplished, for example, by processor 130 interacting with exemplary imaging article 120 to obtain, access, and/or read information (e.g., data) stored on second memory 124 to form an image. This is done by obtaining unsigned consumable management data from supplies 120 . The printer is authorized (commanded and/or enabled) to print using the unsigned consumable management data (block 222). This includes, for example, processor 130 using the unsigned consumable management data to create consumable gauges, monitor print yield of imaging article 120 , render desired colors, and configure printer 100 . by heating a component (e.g., fuser 118) to a threshold temperature and/or heating its component (e.g., fuser 118) to a threshold temperature at a threshold speed and/or within a threshold time frame. will be

If authorization to use the unsigned consumables management data has not been obtained, the printer is allowed to print without using the unsigned consumables management data (block 224). This is done, for example, by processor 130 using default settings stored on data storage device 126, which, for example, instruct processor 130 to configure components of printer 100 (eg, fuser 118). Heating to a threshold default temperature and/or heating the component (eg, fuser 118) to a threshold default temperature at a threshold default speed and/or within a threshold default timeframe. In some examples, if permission to use unsigned consumable management data has not been obtained, printer 100 may not be able to print and/or display consumables on display device 110, for example. Gauges may not be created and/or displayed.

As shown in FIG. 3, if there is signed data on the imaging article, the program obtains a digital signature (block 302).
