Cartridge
Position
Detection
The press/separation of the toner cartridge is detected by the toner
cartridge position sensor (PS3) by monitoring the position detection
flag. When the cartridge is separated from the drum, the flag interrupts
PS3 and the toner cartridge position sensor signal (
/DEVCAM) is set to
“L.” When the cartridge is pressed against the drum, the flag leaves
PS3 and
/DEVCAM is set to “H.” The relationship between the cartridge
press cam, press detection flag, and the press sensor is shown below.
