Embodiment 1

[0032] This embodiment provides a method for resetting a replaceable unit. The replaceable unit includes an old chip module and a command processing module connected to the old chip module.

[0033] The old chip module is the IC in the old chip, it can also be the old chip circuit module composed of the old chip IC and related peripheral electronic accessories, or the microcontroller in the old chip. In this embodiment, the described Command processing module one is the old chip IC.

[0034] The command processing module can be a microcontroller with a storage unit and a control unit, and has the functions of receiving commands, storing data and executing commands. In this embodiment, the IC in the old chip module and the microcontroller in the command processing module are two different entities.

[0035] Such as figure 1 As shown, the method for resetting a replaceable unit includes: Step S01: receiving a command sent by an imaging device and judging the command.

[0036]...

Embodiment 2

[0056] This embodiment provides another implementation of a method for resetting a replaceable unit. The structure of the replaceable unit differs from that of Embodiment 1 in that, as Figure 6 As shown, the replaceable unit further includes a command receiving module.

[0057] The command receiving module may be a microprocessor.

[0058] For the communication between the replaceable unit reset process and the imaging device, refer to Figure 7 and Figure 8 ,

[0059] Such as Figure 7 As shown, before writing the consumables information, the imaging device sends commands to the replaceable unit. These commands do not directly communicate with the old chip module or the command processing module, but go through the The command receiving module performs preprocessing, and the command receiving module judges and makes corresponding modules execute corresponding commands for different commands.

[0060] After the imaging device sends the command of writing consumable info...

Abstract

The invention provides a resetting method of a replaceable unit. The replaceable unit comprises an old chip module, and a command processing module connected with the old chip module; and the resetting method comprises the following steps: (S01) a command is received and judged; in the step (S01), if the received command is not a consumable information writing command, the step (S21) is carried out; the command is performed by the command processing module; and then, the step (S01) is returned to; in the step (S01), if the received command is the consumable information writing command, the step (S11) is carried out; consumable information is written in the old chip module; the step (S12) is carried out after the step (S11); and the command processing module is stopped operating. The resetting method of the replaceable unit, provided by the invention, has such characteristics as high resetting recovery rate of the old chip and good stability.

Description

technical field [0001] The invention relates to the field of printing, in particular to a method for resetting a replaceable unit installed on an imaging box. Background technique [0002] With the continuous popularization of printers, the consumption of printer consumables (also known as imaging cartridges, including toner cartridges or ink cartridges, etc.) continues to increase. The chip (also known as "replaceable unit", including IC (integrated circuit) and the corresponding peripheral circuit) on the chip is also discarded together with the waste toner box and cannot be reused, resulting in waste. Although chip recyclers will also reset the discarded old chips to realize the reuse of discarded old chips, the existing reset method is complicated, and for the old chips with high degree of encryption, the reset success rate is low, and after reset The stability of the chip working process is low, resulting in the waste of old chips, increasing the economic pressure of c...
