[. . . ] Bias Seal 57 (7) Toner Cartridge Installation Detection · Toner Cartridge installation detection is made with the Toner Cartridge Detection Sensor (PC8) and the Reflector in the Toner Cartridge. Intensity of Light Reflected Detection Method No Cartridge installed Cartridge installed NO YES Reflector Reflector VCC CPU GND 4131M039AA PC8 4131M040AA 58 (8) Detection of a brand new Toner Cartridge 1. The Toner Cartridge Rack is rotated to bring the Toner Cartridge at the developing position. The Toner Cartridge Detection Sensor (PC8) detects whether or not the Toner Cartridge is installed. The Toner Cartridge Detection Sensor judges that no Toner Cartridge is installed, since no light reflection is made with the Reflector placed under the Cover in the brand new Toner Cartridge. The toner Cartridge, which is detected as "not installed, " is stopped at the developing position. The Reflector placed under the Cover is pushed out in the Toner Cartridge with a rotation of the Developing Roller. The Toner Cartridge Detection Sensor detects that the Toner Cartridge is installed with the light reflection from the Reflector. Other Toner Cartridges are stopped at the developing position respectively. If the Cartridge is a brand new, sequences from 4 through 7 are repeated for each Color Toner Cartridge. According to the above-mentioned sequential operation, the Toner Cartridge is detected as a brand new one.
