2 Troubleshooting the Printer
2.1 Basic Printer Operation
Although the Nanoptix PayCheck™ printer is a complex device, its operation is fairly simple.
The printer requires two consumables to operate, (1) a regulated 24 VDC power source and
(2) approved thermal paper. The printer is equipped with eight communication interface ports
The printer is mounted using a slidding baseplate. This baseplate's home position is detected
by a magnetic sensor. A reflective optical sensor (B) situated in bottom of the ticket tray is used
to detect the last sheet of paper. In order to do this, paper low sensor (C) must installed in
"disable" position This paper low sensor (C) has 3 other mounting positions used to trigger a
paper low condition at varying amounts of paper left in the tray. A third optical sensor (F) is
used in the printing mechanism assembly to detect the presence of paper and start the feeder
motor when loading paper. This sensor also works in conjunction with a fourth optical sensor
(A) situated in the paper chute to realign paper back to its "ready" position.
