How often should I clean the
scanner paper feed rollers?
To ensure optimal scanning
performance, the paper feed rollers
should be cleaned once a week or
when 20,000 sheets or more are fed
into the unit. In an environment
where NCR paper is used, it is
recommended that the paper feed
rollers are cleaned on a daily basis.
Treated papers, like NCR paper,
contain chemicals that cause rollers
to deteriorate at an accelerated rate,
requiring roller replacement much
sooner than scheduled. A good daily
cleaning of the paper feed rollers
with isopropyl alcohol will help to
prolong the life of the rollers in this
harsh environment.
