Waste toner box full detection

• The waste toner full sensor provided on the front side relay board is used to determine
the amount of waste toner accumulated in the waste toner box.
A. Waste toner near-full condition
• The toner collecting screw provided in the waste toner box conveys waste toner in the
box onto the central portion of the box. For more details, see "Control of waste toner con-
veyance through waste toner box".
• There is the detection window for detecting a waste toner full condition provided at the
central portion of the waste toner box. When the waste toner conveyed onto the central
portion of the box exceeds a predetermined height, waste toner spills over the waste
toner full condition detection section.
• The machine determines that there is a waste toner near-full condition, if the waste toner
full sensor is blocked by the waste toner stagnant over the waste toner full condition
detection section for a predetermined period of time or longer.
