MX-M260/M310/M260N/M310N MAINTENANCE 8 - 3
2. Details of Maintenance
A. Process unit
(Note for servicing the OPC drums)
1. Prevention of oily dirt attachment
Note:
• Be careful not to attach fingerprints or oily dirt on the OPC drum sur-
face. (Keep the unit away from oils and dust.)
• When replacing the OPC drum, cover the OPC drum with the protec-
tion sheet and hold the protection sheet.
If it is required to hold the OPC drum directly, use enough care not to
touch the cleaning blade area, 5mm inside from both edges of the
OPC drum. (If a fingerprint or oily dirt is attached to the cleaning
blade area of the OPC drum, the cleaning blade may flip.)
