RTB Reissue
The items in
bold italics
were corrected or added.
Expiration
This is to announce the expiration of the information originally announced in this
bulletin. Considering the time elapsed since December 2011 when the drum charge
unit was modified, it is expected that the drum charge units of the previous type
(D0742195) are no longer used in the field.
This RTB has been issued to announce the troubleshooting procedure for Small Interval
(2-3mm) Banding.
Symptom
Small interval (2-3mm) banding
Cause
Incomplete engagement of the drum charge roller gear causes the OPC drum to vibrate.
Action
Remove the gear from the drum charge unit.
Note
Effectiveness of the above action will vary with each unit.
The drum charge roller will function properly even with the gear removed.
Procedure for Removing the Drum Charge Roller Gear
General Notes
1. Work carefully to prevent the grease applied to the gear from adhering to the drum
charge roller.
2. Make sure that the surface of the drum charge roller is clean and unscratched.
