Title:
IMAGE FORMATION DEVICE AND CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2018/061313
Kind Code:
A1
Abstract:
Provided is a technique for making it possible, in an image formation device and a cartridge used for the image formation device, to reduce the time needed to store different numerical values for different specifications in advance in a memory of the cartridge. This image formation device comprises a sensor for detecting the movement of a protrusion in a cartridge. When the cartridge is mounted onto the image formation device, a control unit of the image formation device is able to increase or decrease a numerical value for managing the lifespan of the cartridge on the basis of a detection signal obtained from the sensor. Modifying the shape of the protrusion for different specifications of the cartridge makes it possible to manage the lifespan in accordance with the specifications. There is thus no need to have stored different numerical values for different specifications in advance in a memory of the cartridge.
