Collecting Used Toner - Ricoh Neptune-P1 Service Manual

Collecting Used Toner

The cleaning unit auger [A] pushes toner into the used toner collection bottle [B].
The used toner bottle motor [C] moves a cam [D] from side to side, to hit the side of the used toner collection
bottle. This causes a vibration, and this keeps the level of used toner in the bottle flat. The motor never
switches on during a job, to prevent this vibration from causing a malfunction.
The motor operation timing is controlled as follows:
• When the used toner overflow sensor detects that the used toner tank is almost full, the motor switches
on for 20 seconds at the end of the job (SP2926-1). During the motor operation, printing and scanning
cannot be done.
• After a new toner cartridge is installed and the cover is closed, the motor switches on for 30 seconds.
(SP2926-2).
If the used toner overflow sensor [E] still detects toner after 20 seconds of vibration, the overflow indicator
on the operation panel starts to flash:
• Printing can continue until the end of the job. But, if 15 more meters are printed before the end of the
job, printing stops at the 15-meter point.
• After 15 meters of copying, or at the end of the job, the overflow indicator stops flashing and stays
on. The machine cannot be used until you remove the used toner from the collection bottle.
• The length of paper that can be printed after the toner-bottle-full indication can be made shorter
or longer with SP2926-3 (Used Toner Control – Used Toner Overflow Detection).
