5 SENSOR OPERATION
5.1 Paper Out Sensor
The paper out sensor is located within the pivoting printer head module and is used to terminate the
print operation when paper has run completely out, and for proper form registration. The PSA-66-ST
will cease printing and feeding operations once a paper out condition is detected. A paper out condition
is corrected automatically by loading more paper to the unit.
5.2 Paper Low Sensor
The paper low sensor is located in the paper well, and is used to determine when the paper stack has
approximately 30 tickets remaining. A paper low condition will be automatically reset once a stack with
a greater height has been loaded. Paper low sensing only runs when the system is at idle and takes a
few seconds to detect the new paper level.
5.3 Paper Present Sensor
The paper present sensor is located in the presentation chute of the unit and is used to determine when
the customer has actually taken their cash-out voucher.
5.4 Paper Jam Sensing
The printer supports detection of a paper jam condition through use of the paper present sensor.
