Troubleshooting

This chapter gives the solutions to some of the more common printer problems.

Power problems

The POWER light does not come on.

Make sure that the power supply cables are correctly plugged into the printer, the power unit, and the power outlet.

Make sure that power is supplied to the power outlet. If the outlet is controlled by a switch or timer, use another outlet.

Printing problems

The ERROR light is on (not flashing) and nothing is printed.

If the PAPER light is also on, the paper is not loaded or is near the end of the roll. Install a new roll of paper.

If the PAPER light is not on, probably the printer cover is open. Close the printer cover.

The ERROR light is flashing and the printer does not print.

There may be a paper jam in the auto cutter. If there is a paper jam, clear it by following the instructions later in this chapter.

The print head may be too hot. Printing stops and the error light flashes if the print head is too hot. Printing automatically resumes when the print head cools.
