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 three communication interface ports:
one power/communication port situated at the bottom rear of the unit, one USB port at the top
rear of the unit and one maintenance USB port situated on the side of the printer. A 3-pin I/O
connector situated at the front of the unit can be used to control an external illuminated bezel.
The two main components of the printer, the base assembly and the main bracket are
connected together via a white flat cable. A photo-interruptible sensor (D) is used to detect the
main bracket’s pocketed (open/close) status. A reflective optical sensor (B) situated at the front
of the ticket tray is used to detect a low paper condition. On newer models of the Paycheck
™
,
the paper low detection has been moved to the side of the ticket tray (C). 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.
When the sensors are not reporting any errors and a recognized data stream is sent to the
printer, a printed ticket will result.
