Operational descriptions
a. Waste toner full detection operation
Waste toner generated in the OPC drum and the primary transfer
cleaning section is transported to the waste toner box by the waste
toner transport screw which is driven by the paper feed motor.
The toner collection box section is provided with the waste toner full
detection mechanism. When the waste toner quantity in the toner
collection box becomes full, the rotation load of the waste toner
transport screw increases and the waste toner transport screw
drive coupler is stranded to turn ON the waste toner full detector
(TNFD).
When the waste toner full detector is turned ON continuously for 1
sec, it is judged as near end, and the message is display to indicate
that the replacement of the toner collection box is approaching.
