MAGPRO CLEANING: IF ANY OF THESE PROCEDURES ARE PERFORMED TO YOUR VALIDATOR AFTER IT IS
RETURNED UNDER A WARRANTY REPLACEMENT, YOU WILL BE SUBJECTED TO A $65.00 LABOR FEE.
CLEANING AND MAINTENANCE:
Note: Petroleum-based cleaners and freon-based propellants can damage plastic and some electronic components.
Scouring pads and stiff brushes may harm the protective conformal coating on the circuit boards and can mar the
plastic. These items should never be used when cleaning the MAGPRO bill acceptor.
The MAGPRO should be cleaned every 7,000 bills
or every 4 -6 months (or as needed, depending
on the environmental 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
the dust from around the intermediate frame and
stacker plate.
3. Remove the lower track.
4. Using compressed air or a soft brush, blow or
brush the dust off of the optic sensors and out of the
recessed sensor openings.
5. Remove dust from around the belts and wheels on
the lower housing and the sensors on the upper
sensor board. The upper sensors are located directly
above the lower housing sensor when the lower
housing is installed.
6. The bill path can be cleaned to remove further dirt
and oil using a soft cloth moistened with a mild soap
and water solution.
7. Clean the magnetic head using a swab and
isopropyl alcohol.
8. Once the lower housing is dry, place it back into
the mainframe so that the tab on the bottom locks
into place.
9. Blow the dust out of the encoder wheel and its
sensors. (It may be necessary to extend the stacker
plate to access the encoder wheel. Supplying power
to the unit momentarily can do this, so that the
stacker plate extends.)
10. Remove dust from the transport belt areas and
from any other places of build up.
11. Remount the bill box.
12. Apply power and insert bills to verify that the unit
is functions property.
MAGPRO CLEANING PROCEDURE FOR SALT
WATER POLLUTED UNITS:
Note: Petroleum-based cleaners and freon-based
propellants can damage plastic and some electronic
components. Scouring pads and stiff brushes may
harm the protective conformal coating on the circuit
boards and can mar the plastic. These items should
never be used when cleaning the BA30 bill acceptor.
Procedure:
1. Remove power from the bill acceptor.
2. Remove the bill acceptor from the vending
machine.
3. Open the bill box lid and verify that the stacker
plate is in the stand-by/home position. If it is not
in the home position, apply power and observe
that the stacker plate returns home.
Warning: If moisture is present, allow the unit to dry
thoroughly before applying power to avoid possible
shock hazard. If the stacker plate does not return to
the home position, remove power and carefully
remove the bill box to avoid damaging the bill box
and/or stacker plate.
4. Remove the lower housing.
5. Remove the bottom cover from the lower
housing.
6. Run hot water (1101/4-1401/4F) over the lower
housing from the top and bottom. Using a soft
brush, gently clean any residual salt. Use a soft
absorbent cloth to clean any residue off the lower
housing. If the transformer gets wet, allow the
unit to dry for 24 hours before applying power.
7. Remove the front mask. Using hot water and a
soft brush, clean the front mask, upper sensor
board, main frame anti-pullback levers and
position sensor mount.
Caution: The motors are not protected from water,
therefore the unit must be held in a manner that
prevents water from running over the intermediate
frame crossbar.
8. Remove the position sensor cover on the crossbar
and carefully lift the LED from its mount. (Early
models only.)
Caution: Protective coating on the LED leads should
not be damaged. Clean all salt residue from the
mount, sensor hole and detector area.
The detector can be seen through the sensor hole,
and is located in the chassis. Replace the position
sensor cover. (Early models only.)
9. Verify that the anti-pullback levers move freely
and that the spring returns them to their open
position.
10. Allow the unit to dry thoroughly.
11. Clean the magnetic head using a swab and
isopropyl alcohol.
12. Replace the front mask
13. Replace the lower housing cover.
14. Replace the lower housing into the main frame.
15. Remount the bill box.
16. Apply power and insert bills to verify that the unit
is functioning properly.
6 OR 7 ERROR CODE FLASHES
The cleaning procedure for this common occurrence is
listed below. Just follow these steps.
1. If this code has occurred on a new machine or
one that the validators DIP switches were just
changed, Ensure that all the white plugs on the
side of the validator board away from the red LED
are plugged in securely.
2. Remove the bill box.
3. Turn the Changer ON then OFF in an attempt to
stop the metal push plate so that it COASTS into
the fully outward position.
4. Using an air compressor or a can of compressed
air blow out the area behind the push plate until
it is completely free of all dust and lint.
5. Turn the changer power back on so that the push
plate returns to the inward position. If the same
error code persists, repeat steps 1 - 3
concentrating on the top center area behind the
plate.
6. Replace the bill box.
