1.3 Paper Loading
The paper stack should be changed when it is low or out.
Caution: The printer will not operate without paper, but it may continue to accept data from the
host computer. Since the printer cannot print any transactions, the data may be lost.
The maximum stack that will fit in the ticket cartridge is 200, 400, 600 or 800 tickets depending
on the cartridge option that was purchased with the printer.
Ticket stack orientation:
The stack must be oriented so
that it’s top of form mark is on the
leading edge of the ticket.

1.6 Testing the Printer
This test can be used to verify the correct operation of the printer. The test prints a resident
ticket listing the current printer settings. This ticket can also be used to verify the printing quality.
PayCheck & PayCheck 2:
To print the test ticket, power-on the printer while pressing and holding the Paper Feed Button
for approximately 5 seconds. Once repetitive beeping is heard, release the paper feed button.
A test ticket similar to the one below will be printed. Pressing the button again will result in
blank tickets.
PayCheck 3 & Paycheck 4:
To print the test ticket, the printer must be powered “ON” while holding the paper feed button for
approximately 5 seconds. A status ticket similar to below will be printed. Pressing the button
again will result in blank tickets.

2 Troubleshooting the Printer
2.1 Basic Printer Operation
Although the Nanoptix PayCheck 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 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 is used to detect the
main bracket’s open/close status. A reflective optical sensor situated at the front of the ticket
tray is used to detect a low paper condition. A third 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 fourth 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.
