(1) Cleaning blade
• The cleaning blade, of a fixed blade type, is pressed up against the surface of the transfer belt at all times. No cleaning blade retraction
mechanism is provided.
• The waste toner on the surface of the transfer belt is scraped off as the transfer belt is rotated.
(2) Waste toner conveying/collecting mechanism
• Drive for the toner collecting screw comes from the transfer belt driven roller. (The toner collecting screw rotates in time with rotation of
the transfer belt.)
• The rotation of the toner collecting screw conveys waste toner scraped off the surface of the transfer belt toward the front of the machine.
• There is a caking-of-toner prevention blade installed. It prevents waste toner from caking at the toner collecting screw portion.
• The waste toner is discharged through the toner collecting port into the waste toner box.
• The waste toner is disposed of when a waste toner box which is detected to be full of waste toner is replaced with a new one and the
used waste toner box is discarded.
