fore susceptible to scratches.
• Even when the PC Drum is only locally dirtied, wipe the entire surface.
• Do not expose the PC Drum to direct sunlight. Clean it as quickly as possible even under
interior illumination.
• If dirt remains after cleaning, repeat the entire procedure from the beginning one more
time.
