Drive Roller Cleaning and Inspection
Dirty or worn drive rollers are a common source for bill jams and poor acceptance.
These rollers should be cleaned and inspected once a year for optimum performance.
1.
Measure the diameter of each drive roller using a caliper tool. If the roller is in
proper specification, clean as necessary. If not replace with new.
2.
To clean the roller, use a clean rag, slightly dampened with denatured alcohol. Press
on the rollers and wipe until clean.
Note:
1.
A motor driver software chip is available which will run the motor when there is
power to the acceptor. This software comes in both the Intel and Phillips version.
2.
Shiny rollers may first be “ruffed-up” using a medium grade sand paper before
wiping with a damp clean rag. Care should be taken as not to remove too much
material. Always re-measure the diameter after this procedure.
