Do not use alcohol, selenium refresher and other organic solvents or silicon oil as they will
have an adverse effect on the drum.
• Scratches on drum surface
If the surface is scratched in such a way that the aluminum substrate is exposed, no copy
image will be produced on this area. In addition, the cleaning blade will be damaged so
replacement with a new drum will be necessary.
• Collecting used drums
Regarding the recovery and disposal of used drums, we recommend following the relevant
local regulations or rules.
* G3: Drum cleaning blade
• Handling precautions
Pay attention to the following points as the cleaning blade life is determined by the condition
of its edge. Since the edge of the blade is vulnerable and can be easily damaged by factors
such as the adherence of paper dust.
- Do not allow hard objects to hit or rub against blade edge.
- Do not rub the edge with a cloth or soft pad.
- Do not leave oil (or fingerprints, etc.) on the edge.
- Do not apply solvents such as paint thinner to the blade.
- Do not allow paper fibers or dirt to contact the blade edge.
- Do not place the blade near a heat source.
• Cleaning procedure
Clean the blade edge with a cloth moistened with water and squeezed lightly.
Replace the cleaning blade with new ones if poor images are copied due to the damaged
blade regardless of the number of output pages which have been made
* G4: Side seal
When replacing the drum cleaning unit, check that there is no gap between the blade and side
seals on both ends. If there is, or when the side seals put pressure to the cleaning blade,
reattach the side seals on the position shown in the figure (by slightly pushing them to the
direction of the arrows).
