MAG50 CLEANING MAINTENANCE
PROCEDURE
NOTE: Petroleum-based cleaners and freon-based
propellants can damage plastic and some electronic
components. Scouring pads and stiff brushes may harm
the protective coating on the circuit boards and can mar
the plastic. These items should never be used when
cleaning the MAG bill acceptor.
The MAG50 should be cleaned every 20,000 bills or
every two years (or as needed, depending on the environ-
mental conditions of the location). Dust can be removed
with a soft brush or cloth or it can be blown out using
compressed air.
Procedure
1. Disconnect power from the bill acceptor.
2. Remove the bill box and use a soft cloth to wipe any
dust from around the intermediate frame and stacker
plate.
3. Remove the lower housing.
4. Using compressed air or a soft brush, blow or brush
the dust off of the optic sensors.
5. Remove dust from around the rollers on the lower
housing and the sensors on the upper sensor board.
The upper sensors are located directly above the
lower housing sensors when the lower housing is
installed.
6. The bill path can be further cleaned of any dirt or oil
by using a soft cloth moistened with a mild soap and
water solution.
7. Clean the magnetic head with a cotton swab and
isopropyl alcohol.
8. Remove dust from the transport belt areas and any
other places of build up.
9. Once the lower housing is dry, place it back into the
mainframe making sure the tab on the bottom locks
into place.
10. Remount the bill box.
11. Apply power and insert bills to verify the unit is
functioning properly.
