10.5 Feed Roller Cleaning Procedure
The DEClaser 3200 upper and lower paper feed rollers are designed to last for
approximately 1 million prints, without periodic cleaning. Cleaning might be
necessary if the customer uses excessively dusty stock or two sided preprinted
forms.
Unless referred here by another FIP, use the following guidelines to determine
when to clean the paper feed rollers:
• Every time the fusing unit is replaced after printing 300,000 pages.
• If you notice an increased number of 0821 or 0822 upper or lower cassette
feed failures.
• If you notice increased skewing from the upper or lower cassettes.
A special tool and alcohol towelettes are available for cleaning the feed rollers,
see Section D.2 for the part numbers. If the special tool is not available and
the rollers need cleaning, you must disassemble the printer to access the feed
roller, and clean it with an alcohol soaked towelette or replace the feed rollers,
as shown in Section 9.50 and Section 9.52
Use the following procedure to clean the surface of the upper or lower feed
roller with the special cleaning tool:
