Operator's Guide
Scantron scanners use replaceable tires than can feed
NOTE:
a wide range of document types, sizes and thicknesses.
Tire life and performance will vary based on the docu-
ment set, the frequency of cleaning of the transport
and tires, and following the recommended schedule
for changing tires. You should change the tires if you
notice an increase in multiple feeds, stoppages, or a
decrease in feeder performance that is not resolved by
the above cleaning procedures.
NOTE: Certain paper types (such as carbonless paper or
newsprint), failure to clean regularly, and/or use
of non-recommended cleaning solvents can shorten
tire and roller life.
