Problems solved by technology

When other imaging cartridges with the same serial number are installed on the printing imaging device, since the serial number has been recorded in the printing imaging device, the printing imaging device will judge that the memory chip of the imaging cartridge is illegal, so it cannot continue to repeat use

Embodiment 1

[0073] see figure 1 , which is a flow chart of Embodiment 1 of the method for sending parameters of the memory chip of the imaging box provided by the present invention.

[0074] The method for sending parameters of the memory chip of the imaging box provided in this embodiment includes the following steps:

[0075] S101: Receive an instruction sent by a printing and imaging device;

[0076] It should be noted that the instructions sent by the printing and imaging device to the storage chip of the imaging box may include reading instructions and other types of instructions. The reading instruction refers to the need to read certain parameters from the storage chip to the printing and imaging device .

[0077] Of course, it can be understood that some instruction types do not need to read parameters from the memory chip to the printing and imaging device.

[0078] S102: When it is judged that the instruction is a key parameter reading instruction, send the key parameter to t...

Embodiment 2

[0084] see figure 2 , which is a flow chart of Embodiment 2 of the method for sending parameters of the memory chip of the imaging box provided by the present invention.

[0085] S201: Receive an instruction sent by a printing and imaging device;

[0086] S202: When it is judged that the instruction is a key parameter reading instruction, send the key parameter to the printing and imaging device, and the key parameter is generated by the memory chip itself.

[0087] S201 and S202 are the same as S101-S102 in the first method embodiment, and will not be repeated here.

[0088] S203: When it is judged that the instruction is a non-critical parameter reading instruction, send the pre-stored non-critical parameter to the printing and imaging device.

[0089] The non-critical parameters are parameters pre-stored by the memory chip.

[0090] It should be noted that non-key parameters can still be stored in the memory chip. These non-key parameters can be read directly and do not...

Embodiment 3

[0092] see image 3 , which is a flow chart of Embodiment 3 of the parameter sending method of the memory chip of the imaging box provided by the present invention.

[0093] It should be noted that both the key parameter read instruction and the non-key parameter read instruction belong to the read instruction. In addition to the read instruction, it may also include a calculation instruction. The calculation instruction in this embodiment is the key parameter generated by the memory chip itself. One of the calculation conditions for parameters, the calculation instructions referred to in the present invention are not the instructions defined by the printing imaging device for instructing the storage chip to perform calculations, but the instructions defined by the storage chip for all instructions that can be used to generate calculation results. Collectively, it may include the above-mentioned key parameter reading instructions and non-key parameter reading instructions. Th...

Abstract

The invention provides a parameter sending method of a storage chip of an imaging box, the storage chip and the imaging box. The method comprises the following steps of receiving an instruction sent by printing imaging equipment, and sending a key parameter to the printing imaging equipment when the instruction is judged as the key parameter reading instruction, wherein the key parameter is generated by the storage chip. The parameter needing to be read by the printing imaging equipment is generated by the storage chip, when the printing imaging equipment sends the reading instruction, the parameter generated by the storage chip is sent to the printing imaging equipment, the parameter cannot be directly read by the printing imaging equipment at any time, and therefore certain important parameters in the storage chip can be prevented from being obtained maliciously. Furthermore, a compatible manufacturer or an original manufacturer of the storage chip does not need to store the complete and specific parameter in the storage chip, a competitor can be prevented from directly reading the storage chip and obtaining certain important parameters, and therefore certain important parameters in the storage chip can be protected.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201410023694.0 and the title of the invention "Memory Chip and Parameter Generation Method" filed with the China Patent Office on January 20, 2014, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to the technical field of printing and imaging, in particular to a method for generating and sending parameters of a storage chip of an imaging box, a storage chip and an imaging box. Background technique [0003] Installing imaging cartridges (such as ink cartridges, toner cartridges and toner cartridges) with memory chips on printing imaging devices (such as inkjet printers, laser printers, LED printers, copiers or all-in-one machines) is a common application in recent years , the memory chip stores information about the imaging cartridge. When the imaging box is installed on the printing and imaging device, the...
