Memory chip, imaging box, serial number replacement method and method for using memory chip

Abstract

A memory chip provided by the invention includes a communication unit, a control unit and a storage unit. The invention also provides a method for using the memory chip. A plurality of different pieces of serial number information and marker information / access marker information which indicate whether currently-selected serial number information is valid or not, are stored in a storage unit; a control unit judges whether serial number information that is transmitted to an imaging device is confirmed valid according to a preset strategy; the selected serial number information is independently replaced according to judgment results when preset conditions can be satisfied; and therefore, modes of the replacement of serial numbers of the memory chip can be more convenient, and user experience can be greatly improved, and the problem of incapability of being used of the memory chip caused by the identity of the serial numbers can be solved.

Description

technical field [0001] The invention relates to printing and imaging technology, in particular to a storage chip, an imaging box and a method for using the storage chip. Background technique [0002] With the development of imaging technology, imaging devices like laser printing devices and inkjet printing devices have been widely used. During the imaging process, the imaging device needs the assistance of imaging auxiliary information of the imaging box to complete the imaging process. In addition to being recorded in the imaging device, the imaging auxiliary information of the imaging device is also recorded on the memory chip, such as figure 1 as shown, figure 1 It is a schematic diagram of communication interaction between an imaging device and a storage chip in the prior art. Among them, the memory chip is attached to the imaging box (generally adhered or embedded in the imaging box), the imaging box can be an ink box filled with ink or a toner cartridge filled with ...

Problems solved by technology

However, some imaging devices will record dozens of serial numbers. At this time, if you still use jumpers or combination switches to select, the selection module will become extremely large and complicated, which will undoubtedly increase the cost and increase the difficulty of manufacturing.

Even if the memory chip only stores two serial numbers, such a method of replacing the serial number also needs to set up a corresponding selection module. Because the memory chip is very small, the selection module can generally only be made very small, which is very convenient for users to operate. Not convenient

It is even more inconvenient if the chip needs to be removed from the imaging box to make a selection
