1.3 Paper Loading
Change the paper when the paper is low or out.
Caution: Do not operate the printer or host computer if the printer runs out of paper. The printer
will not operate without paper, but it may continue to accept data from the host computer.
Because the printer cannot print any transactions, the data may be lost.
1) Remove ticket cartridge.
2) Drop ticket stack into ticket cartridge. The maximum stack that will fit in the ticket cartridge is
200.
3) Replace ticket cartridge.
4) Feed ticket into printer mechanism until resistance is met.
5) Paper will feed automatically; paper is loaded and printer is ready to print.
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.
To print the test ticket, power-on the printer while pressing and holding the Paper Feed Button
(figure 3) for approximately 3 seconds. A test ticket similar to the one below will be printed
approximately 5 seconds later. Press the paper feed button once more and the ticket will feed.
Pressing the button again will result in blank tickets.

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.

2.2 Printing Problems
The table below can be used to determine the cause and resolution of the most common
problems that may occur. If the information in this section does not correct the problem, contact
a Nanoptix service representative.
Problem Possible Causes What to Do
Printer Does Not
Function When Turned
On
Paper jam
Noisy Feeder Motor (paper
disengaged)
Paper does not realign itself
when a ticket is printed
Line of print or section missing
lengthwise on entire ticket
Print is light or spotty
Printer not plugged in
Paper width out of specification Test paper width for compliance
Debris or partial ticket stuck in
paper path
Paper’s perforation burst strength
out of spec
Printer is meant to be operated
with paper engaged in the printing
mechanism, failing to do so will
cause gears to grind and slip,
noise may result
Paper’s alignment mark, (which is
the black dot printed on the nonsensitive side of thermal paper)
may be out of specification
Paper’s thermal coating
inconsistent
Thermal printing mechanism
damaged
Thermal print head is dirty Clean print head at recommended
Paper’s thermal coating
inconsistent
Check that printer cables are properly
connected at both ends
Check that the host and power supply
are getting power
Open paper guide and detach roller,
remove debris
Test paper perforation for compliance
Do not operate printer without any paper
engaged in the printing mechanism
Note: Never lubricate gears or any other
part of the printer
The maximum reflectance of the
alignment mark is 15% (infrared). Simply
put, this means that the alignment mark’s
color should be an even/crisp black. If
any white or gray is visible, it is an
indication that the reflectance could be
more than 15%
Change the paper stack to make sure the
thermal coating is not the source
Contact customer service representative
intervals
Change the paper stack to make sure the
thermal coating is not the source
