[0111] S2077. Generate and execute a partial image printing instruction according to the missing image position information.

[0112] Specifically, generate a partial image printing instruction according to the missing image position information, and perform the operation of printing at the missing image position, which is beneficial to printing the recyclable finished product into a qualified finished product. At the same time, only printing at the missing position is beneficial to saving raw materials, reducing costs, and avoiding the phenomenon of repeated printing.

[0113] In one embodiment, referring to Figure 6 , in order to facilitate the control of the product qualification rate, after S2072, the following steps are specifically included:

[0118] S304. If the quantity of scrap finished products exceeds the preset scrap quantity, generate and execute an equipment stop instruction.

[0119] Specifically, the system compares the preset scrapped quantity retrieved from the database with the quantity of scrapped finished products. Taking 100 as an example for the preset scrapped quantity, if the quantity of scrapped finished products exceeds the preset scrapped quantity, taking 101 as an example for the quantity of scrapped finished products, a device stop instruction is generated and the operation of stopping the device is executed. Since the quantity of scrapped finished products is large, it indicates that the device has a fault.

[0120] S305. Generate a device maintenance prompt signal according to the device stop instruction.

[0121] Specifically, the device maintenance prompt signal prompts the worker that the device has a fault and the device needs to be inspected and repaired, which is conducive to reducing the quantity of scrapped finished products and facilitating the control of the product qualification rate.
