e) From pulley F, the belt goes upward to pass over the top of the installation stud to
pulley A.
The section of the belt between pulley F and the installation stud will contact the drum
when the units is mounted in the copier. Also, the section of the belt passing over the in-
stallatation stud is the section that will contact the separation roller during normal machine
operation.
NOTE: Make sure that the belt has no twists after it is installed on the subassembly. Twists,
if present during operation, will cause paper jamming or belt breakage.
4.12-4 REPAIR/SERVICING ACTIONS
1) CLEANING
As the separation belt is constantly in contact with the drum, it becomes dirty after a period
of time. Thus, the belt should be cleaned and the cleaner pad changed periodically to pre-
vent belt marks from appearing on the reproduced copies.
The belt cleaning is accomplished by wiping the belt with Premix-soaked-paper at servicing
intervals.
See the Service Handbook for additional details about assembly cleaning.
