6.4.6 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).
