BULLETIN NUMBER: 6645/6655/6665-040 04/05/95
APPLICABLE MODEL: FT6645/6655/6665
SUBJECT: SHORT BLACK LINES ON DRUM (MEDAKA)
SYMPTOM:
Short black lines appear on the drum surface.
CAUSE:
Certain additives contained in particular varieties of copy paper cause toner to stick to the drum. This occurs
most often when the copier is operated in a warm environment, for example, when the room temperature is
high, or when the copy volume is high (especially when duplex copying).
SOLUTION:
To increase drum cleaning efficiency, a new style cleaning brush has been developed for use with machines
exhibiting the above mentioned symptom. The new style brush (A0969523) contains fewer bristles, however,
the diameter of the bristles has been increased.
NOTE: The new style Cleaning Brush should be used only for units exhibiting the above mentioned
symptom as use of this brush may decrease the life of the drum.
ORDERING PROCEDURE:
The new style Cleaning Brush (A0969523) can be obtained through normal NSPC channels.
