* G2: Drum
• Handling precautions
If fingerprints or oil adhere to the surface of the drum, its properties may degrade, affecting
the quality of the copy image. So, wear gloves to avoid touching the drum surface with your
bare hands. Be sure to handle the drum carefully when installing and removing it so as not to
damage its surface.
• Do not use “patting powder” (lubricant)
Since “patting powder” may affect the initial image if it adheres to the OPC surface, do not
apply it. The friction between the drum and cleaning blade is sufficiently small without it and
no problem would occur even if it is not applied.
