Polishing Roller
The polishing roller polishes the surface of the transfer belt to prevent adhesion of fixing oil to the
photosensitive drum, particularly in two-sided copying mode, thereby preventing foggy images.
The transfer belt is polished in response to a press on the power switch after having made 5,000 copies
(cumulative), and the operation is continued until the transfer belt has made 30 rotations.
The polishing roller is butted against the transfer belt when the polishing/oil removing motor (M15)
rotates clockwise and the polishing roller solenoid (SL18) turns on, rotating the cam through the control ring
and operating the push-on spring.
The polishing roller is moved away from the transfer belt when the solenoid turns off to move the cam
before it meets the seam.
The polishing roller rotates slightly to change its position of contact against the transfer belt when the
operation of the transfer belt lifter pushes the one-way clutch lever.
If the polishing/oil removing motor rotation speed deviates because of an error, ‘E018’ will be indicated
on the control panel.
