D. Removal procedure
• The Toner Cartridge is pressed in the predetermined position. Pushing down the front
handle once will disengage the lock pawl.
• Hold the front handle with your right hand and withdraw the Hopper.
• When the drop preventive claw of the upper handle is about to hit against the machine
frame, raise the upper handle. This retracts the drop preventive claw.
• Holding onto the upper handle with your left hand, slide out the Toner Cartridge.
3.3.3 Toner Cartridge life control
• The Toner Cartridge life is determined based on toner empty condition detection and the
period of time through which the Photo Conductor has been turned.
• Each Toner Cartridge is provided with a TC Detection Board (CSIC) that detects a new
TC, a toner near-empty condition, and a toner empty condition.
A. Cartridge detection and new cartridge detection timing
• The machine attempts to perform a detection sequence when the Front Door is closed.
B. Cartridge detection
• The machine accesses the TC Detection Board (CSIC) to check for data stored in it.
Using that data, the machine determines whether or not a cartridge is loaded.
C. New cartridge detection
• After a cartridge has been detected, the machine determines whether it is new or not
based on the data acquired.
D. Operation after new cartridge detection
