Control of waste toner conveyance through waste toner box

• Waste toner in the image transfer belt unit and drum units, and excess toner in the devel-
oping unit/K are conveyed onto the waste toner box by the toner collecting screw.
• Waste toner and waste developer (waste carrier/K + waste toner/K) are collected through
the toner collecting ports (at five places) and the developer collecting port.
• The waste toner collecting port is provided with a toner agitating blade that prevents
toner from stagnating.
• The toner agitating blade is moved up and down as the toner conveying screw rotates.
* The developer collecting port is not provided with any toner agitating blade.
• Toner collecting screw 1 and toner collecting screw 2 (dedicated to the transfer belt toner
collecting port) are installed in the waste toner box.
• The screws provided on both ends of toner collecting screw 1 function to convey waste
toner stagnant in the box uniformly onto the central portion of the box.
• Toner collecting screw 2 functions to convey toner conveyed from the image transfer belt
unit uniformly onto the central portion of the box.
• The paddle provided at the central portion of toner collecting screw 1 evens out the
waste toner conveyed onto the center of the box.
• There is a detection window for detecting a waste toner full condition provided at the cen-
tral portion of the 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 window. For details, see "Waste toner box full detection".
