PREVENTIVE MAINTENANCE (PM)
5 - 27
* F5: Recovery blade
Clean the surface of the recovery blade with a soft pad or cloth, if dirt cannot be removed with a
vacuum cleaner. If the edge of recovery blade is damaged, replace the blade regardless of the
number of output pages.
Never use water or alcohol for cleaning the transfer belt recovery blade.
* F7: Drum surface potential (VO) sensor / G8: Drum surface potential (VO) sensor shutter
Clean them with a vacuum cleaner.
When cleaning them, be careful not to let any toner or developer material enter into the detecting
section of each drum surface potential (VO) sensor.
* F13: Toner filter
If the toner filter is not replaced at the specified replacement timing, the suction efficiency against
the scattered toner decreases, and thus it may cause suction failure and the amount of scattered
toner in the equipment may increase. So be sure to replace it periodically.
