Image forming apparatus

Abstract

The invention relates to an image processing system aiming to provide an image processing system to use a used component part as a new component part; the various information about the used component parts is replaced by the information necessary for the new component parts; the used component parts are managed and controlled according to the standard of the new component parts. The detailed information about the image processing system is as following: one of the plurality of devices used for forming images in the image processing system 100 is a serving device 26 Y at use stage which is used as a unused device to be used in an image processing system 100'; the serving device 26 Y at use stage is provided with a detection device 26S which detects the state of the serving device; a memorydevice which stores the initial information of the serving device 26 Y; the image processing system 100' also comprises a control unit 1000' which reads the information stored in the memory device and sets the information into used information.

Description

technical field [0001] The present invention relates to an image forming apparatus, and more particularly, to management and control of developer concentration when a used developing device is reused as an unused developing device. Background technique [0002] In an image forming device such as a copier, a printer, a facsimile device, or a printing machine, the image forming process usually includes, for example, taking an electrophotographic method, forming an electrostatic charge corresponding to the original or image information on the photoreceptor of the latent image carrier. Latent image, after the electrostatic latent image is processed by the toner provided by the developing device, it is transferred and fixed on the recording sheet, and finally copied and output. [0003] However, if the image forming apparatus has a device abnormality due to a malfunction or the like, or is in an operating state when the product reaches the end of its life, parts or devices need t...

Problems solved by technology

For this reason, when the developing device in the new process box is no longer a new product when it has been used, because it is impossible to know the amount of developer remaining in the developing device or the setting conditions of the line speed are different, if the once used If the management data of the developing device is used as the control program data preset for a new developing device in the developer concentration management control section without any modification, there will be an error with the actual developer concentration, and if the If the error is used for concentration management, the accuracy of concentration management will decrease.
