MISCELLANEOUS PROBLEMS
The following problems may occur in the Bill Changer without causing a fault code.
ERRATIC PAYOUT
Problem:
The changer is not consistently dispensing the correct number of coins.
Symptom:
One vend is short a coin. The next vend contains an extra coin.
Corrective Action:
1.
Check the coin chute on the back of the dispenser.
Most likely, a coin is
getting hung up in the dispenser coin chute, after it has been “counted” by the
detector, then being shaken loose by a later vend. Check the coin chute for any dirt
or obstruction that might cause a coin to hang up.
LARGE NUMBER OF VALID BILLS REJECTED
Problem:
The bill acceptor rejects a large number of valid bills.
Corrective Action:
Refer to the Troubleshooting Chart in the
Bill Acceptor Field Service Manual and Parts
Catalog
included with your Bill Changer.
BILLS JAM FREQUENTLY
Problem:
Bills repeatedly become jammed in the Bill Acceptor transport.
Corrective Action:
Refer to the Bill Jamming Checklist in the
Bill Acceptor Field Service Manual and Parts
Catalog
included with your Bill Changer.
