2.4.4.2 Development Position
TONER CARTRIDGE RACK STOP POSITION FOR DEVELOPMENT
The toner cartridge for each color is stopped at the development position by the operation of
the Rack Lock Lever and the Rack Position Detection Sensor (PC4).
The Toner Cartridge Rack rotates, the Rack Lock Lever drops into the groove for stopping
at development position, the light to the Rack Black Position Detection Sensor (PC4) is
transmitted and the toner cartridge the relevant color stops at the development position.
STANDBY POSITION OF TONER CARTRIDGE RACK
The standby position is such that the stop position for development is 20 degrees before the
black toner cartridge.
When the Toner Cartridge Rack rotates and the Rack Lock Lever passes the groove for
black position detection (light to PC4: intercepted Å® transmitted), rotation of the rack is
decelerated.
