Theory of Operation
When the Toner Cartridge Rack is stationery at the developing position, the
Developer Roller drive gear meshes with intermediate gears allowing the
Developing Motor to engage the roller.
Toner Cartridge Rack
The Toner Cartridge Rack holds the four Toner Cartridges and rotates to position
each cartridges’ Developer Roller in the developing position. The rack is driven by
the Rack Motor.
The Toner Cartridge Rack has three stop positions driven by the Rack Motor: the
standby (reference) position, the developing position, and the cartridge
replacement position.
•
The standby position is the Toner Cartridge Rack position when the system
completes a warm-up cycle or waits for a print command.
•
The development position is when the Toner Cartridge Rack stops during
development of a specific color of toner.
•
The cartridge replacement position refers to the position at which the Toner
Cartridge Rack is stopped for replacement of the Toner Cartridge of a specific
color of toner.
