[0040] S301: acquiring capacity information of the storage unit and / or content data stored in the storage unit;

[0041] S302: judging whether the consumable chip is legal based on the capacity information and / or the content data.

[0042] ​The execution subject of the image forming control method based on the consumable chip is an image forming device, specifically an image forming control unit arranged in the image forming device.

[0043] In S301, the image forming control unit specifically acquires the capacity information of the storage unit and / or the content data stored in the storage unit by communicating with the consumable chip. The image forming device can send a request for acquiring the capacity information of the storage unit and / or the content data stored in the storage unit to the consumable chip, and the consumable chip can acquire the corresponding content based on the request. Alternatively, the consumable chip can actively feed back the information to the image forming device, which is not limited herein.

[0044] The capacity information of the storage unit specifically refers to the size of the storage space of the storage unit included in the consumable chip.

[0045] In S302, after acquiring the capacity information of the storage unit and / or the content data, it can be determined whether the consumable chip is legal. When the consumable chip is legal, it means that the consumable chip meets the security requirements and is trustworthy. When the consumable chip is not legal, it means that the consumable chip does not meet the security requirements and may cause the risk of information leakage.

[0046] Specifically, S302 can include the following steps:

[0047] It is determined whether the capacity information of the storage unit exceeds a preset threshold. If yes, it is determined that the consumable chip is not legal.

[0048] The preset threshold can be directly stored in the image forming control unit or in other storage in the image forming device, which is not limited herein.

[0049] In the embodiments of the present application, the capacity information of the writable storage unit of the consumable chip is limited, so as to control the consumable chip and avoid the information security problem caused by stealing confidential information by the consumable chip of the illegal user.

[0054] It should be noted that, in the embodiments of the present application, the preset service data can also be other data in addition to the consumable consumption information, the consumable attribute information, and the image forming control parameter, which is not limited herein.

[0055] In the embodiments of the present application, by limiting the content stored in the writable storage unit of the consumable chip, the content stored in the consumable chip is controlled, and the information security problem caused by the illegal user stealing the confidential information through the consumable chip is avoided.

[0056] Specifically, S302 specifically includes the following steps:

[0057] If the capacity information of the storage unit does not exceed the preset threshold, it is further determined whether the content data in the storage unit contains the preset service data. If the content data contains the preset service data, it is determined that the consumable chip is illegal.

[0058] In the embodiments of the present application, by limiting the capacity of the writable storage unit of the consumable chip and the content data stored in the writable storage unit, the consumable chip is controlled, and the information security problem caused by the illegal user stealing the confidential information through the consumable chip is avoided.

[0059] Specifically, in S302, when it is determined that the consumable chip is legal, the consumable can be used for imaging according to a first preset requirement, and when it is determined that the consumable chip is illegal, the consumable can be used for imaging according to a second preset requirement or not used for imaging, and a prompt information indicating that the consumable chip is abnormal is output. The normal image quality can be obtained by using the consumable for imaging according to the first preset requirement, and the speed of imaging and / or the obtained image quality do not meet the user's expectation when the consumable is used for imaging according to the second preset requirement.

[0060] Further, when the storage capacity of the writable storage unit in the consumable chip and / or the content data containing the preset service data in the writable storage unit are detected, the abnormal event can be recorded, such as the time of the event, the content data stored in the storage unit, and the like, so that the subsequent trace can be performed.

[0061] Further, the above method further includes Figure 4Steps of the image forming control method based on the consumable chip shown in the embodiment of the present application include:

[0062] S401: obtaining to-be-written data to be written into a storage unit.

[0063] S402: judging whether the to-be-written data contains preset business data.

[0064] If yes, directly S403.

[0065] S403: prohibiting writing of the to-be-written data into the storage unit.

[0066] As shown in the embodiment of the present application, the image forming control method based on the consumable chip further includes: Figure 4 S401: obtaining to-be-written data to be written into a storage unit.

[0067] S402: judging whether the to-be-written data contains preset business data.

[0068] If yes, directly S403.

[0069] S403: prohibiting writing of the to-be-written data into the storage unit.

[0070] In the embodiment of the present application, by limiting the content written into the writable storage unit of the consumable chip, the consumable chip is further controlled and managed, and the information security problem caused by the illegal user stealing the confidential information through the consumable chip is avoided.

[0071] Further, when it is detected that the to-be-written data in the to-be-written unit contains the preset business data, the abnormal event can be recorded, such as the event occurrence time, the to-be-written data and the like, so that the subsequent tracing can be performed.
