Sensor Operations
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 condi-
tion is corrected automatically by loading more pa-
per to the unit.
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.
Paper Present Sensor
The paper present sensor is located in the presen-
tation chute of the unit and is used to determine
when the customer has actually taken their cashout
voucher.
Paper Jam Sensing
The printer supports detection of a paper jam con-
dition through use of the paper present sensor.
