2 Troubleshooting the Printer
2.1 Basic Printer Operation
Although the Nanoptix PayCheck Slim printer is a complex device, its operation is quite simple.
The printer requires two consumables to operate, (1) a regulated 24 VDC power source and
(2) thermal paper. The printer is equipped with two communication interface ports: one mini
USB port and one serial port both located at the top rear of the unit. A 3-pin I/O connector
situated at the front of the unit can be used to control an external illuminated bezel.
A reflective optical sensor situated at the front of the ticket tray is used to detect a low paper
condition. A second optical sensor 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 third optical sensor situated in the paper chute to realign paper back to its
“ready” position.
When the sensors are not reporting any errors and a recognized data stream is sent to the
printer, a printed ticket will result.
