7-1. Developing Position

(1)Toner Cartridge Rack Stop Position for Development

The stop position for development of each Toner Cartridge is determined by the Rack Lock Lever and the Rack Home Position Sensor (PC4).

The Toner Cartridge Rack rotates and the Rack Lock Lever drops into a stopping cutout.

This unblocks the Rack Home Position Sensor (PC4), thus determining the stop position for the Toner Cartridge for the current use.

(2)Toner Cartridge Rack Standby Position

The standby position (reference position) of the Toner Cartridge Rack is 20° ahead of the developing stop position of the black Toner Cartridge.

When the Toner Cartridge Rack rotates and the Rack Lock Lever moves past the black position detection cutout (PC4: blocked -> unblocked), the rotating speed of the rack is decelerated.
