c.Oil Removing Roller
The oil removing roller is used to remove fixing oil from the transfer belt.
REF.
When a double-sided copy is made, the side with toner after fixing is placed
on the transfer belt, causing the fixing oil to move to the transfer belt. If the
transfer belt rotates as it is, the oil will move to the photosensitive drum,
causing fogging or other adverse effects on the next copy image.
When the polishing/oil removing motor (M15) rotates clockwise and the oil removing
roller solenoid (SL18) turns on, the cam starts to rotate by the drive arriving by way of the
control ring, operating the push-on spring and, consequently, bringing the oil removing
roller into contact with the transfer belt.
The oil removing roller remains pressed against the transfer belt; the solenoid remains off.
When the solenoid turns off, the oil removing roller moves away from the transfer belt.
If the rotation speed of the polishing/oil removing motor deviates for some reason, the
control panel will indicate ‘E018’.
