Bill Acceptors (cont.)
A calibration of the ZT1200 bill acceptor may need to
be performed after certain maintenance procedures.
Those procedures that require it will explicitly state that
a calibration must be performed. As a general guide,
any disassembly must be followed up with a calibration.
1. Turn off the bill acceptor and move the mode switch
to the calibration position.
2. Turn on the unit and insert a piece of MARS
calibration paper into the bezel of the bill acceptor
within four seconds. After a few seconds, the
calibration paper will be rejected.
3. Remove the calibration paper from the bezel. The RTU
will perform a run-and-stack operation if the calibration
was accepted. If the unit does not perform a run-and-
stack, the calibration data was not accepted. In this
case, the calibration paper must be re-fed.
4. Allow the ZT1200 to idle for at least 20 seconds
following the run-and-stack operation. Ensure that
all bills, calibration paper or other objects are
removed from the bezel during this period.
5. Turn off the unit and place the mode switch to the
Interface position.
6. Turn on the unit. A run-and-stack operation will be
performed if ready for service.

NOTE: If, after several attempts, the unit
does not perform a run-and-stack, the bill
acceptor may require additional services.
NOTE: The bill acceptor will exit
Calibration mode and return to Interface
mode automatically four seconds after
turning the power on if no calibration
paper is inserted into the unit.
