Method for recording chip use state information, imaging box chip and imaging box

Abstract

The invention provides a method for recording the chip use state information, an imaging box chip and an imaging box. The imaging box chip comprises a base plate, an information memory unit and a control unit, wherein the information memory unit and the control unit are arranged on the base plate, and the information memory unit comprises a prior write-in region and an ordinary read-white region. The method for recording the use state information comprises the following steps that when the chip receives read / write operation commands sent by an imaging device or a control unit arranged on the chip monitors communication interference signals, the control unit arranged on the chip updates the chip use state parameter values stored in the prior write-in region, and the chip use state parameter values are used for carrying out fault analysis on the chip. The imaging box comprises the imaging box chip. The recorded chip use state parameter values can reflect the use state information of the chip per se, and powerful data is provided for discovering and solving the communication problem between the chip and the imaging device.

Description

technical field [0001] The invention relates to imaging technology, in particular to a method for recording chip use state information, a chip of an imaging box and the imaging box. Background technique [0002] With the development of imaging technology, imaging devices such as copiers, printers, facsimile machines, and word processors have been widely used. Imaging devices are equipped with consumables such as imaging boxes that are convenient for users to replace. The imaging boxes are usually equipped with chips, which record the types of recording materials stored in the imaging box, the manufacturing date of the imaging box, the number of imaging pages, and the remaining recording materials. quantity and other information. During the use of the imaging box, the imaging device needs to continuously update the data in the chip on the imaging box, so that the latest state of the imaging box is always recorded in the chip. Therefore, the chip on the imaging box is partic...

AI Technical Summary

Problems solved by technology

However, the above state parameters can only reflect the use state of the imaging box, and do not record the use state of the chip itself

If there is a problem with the chip itself, the imaging box will also be unavailable

The above parameters recorded in the chip in the prior art cannot perform fault analysis on the chip
