Troubleshooting
General problems
The LEDs on the control panel do not light up.
Make sure that the cable is correctly connected and check that power is
being supplied to the entire system.
Printing problems
The ERROR LED is on (not flashing) and the printer will not print.
If the PAPER OUT LED is on, it means that the roll of paper is not fitted or
is almost used up. Fit a new roll of paper.
If the PAPER OUT LED is not on, make sure that the printer cover is closed
properly. Press the printer cover down until it clicks into place.
The ERROR LED is flashing and the printer will not print.
First turn the printer off and check if there is a paper jam.
If there is not a paper jam and the printer has been printing for a relatively
long time, the printhead may have overheated. If the printhead has over-
heated, the printer will continue printing as soon as the head has cooled
down (usually within two to three minutes).
If there is no paper jam and the printhead has not overheated, switch off the
printer and switch it on again after approx. 10 seconds.
The ERROR LED is not on but the printer will not print.
Try to run the self-test to check if the printer is working properly.
If the self-test works correctly, make the following checks:
Check the connection on both ends of the cable.
If the printer still will not print, contact your after-sales service centre or re-
place the printer.
The print quality is poor.
Dust or lint on the heating element of the thermal printhead can affect the
print quality. Try to clean the printhead, as instructed below.
Cleaning the printhead
Caution:
The printhead can be very hot after printing. Do not touch it. Allow it to
cool down before cleaning it.
Do not touch the printhead with your fingers or with a hard object in
order to avoid damaging it
