Troubleshooting

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

General problems

The lights on the control panel do not come on.
Make sure that the power supply cables are correctly plugged into
the printer, the power unit, and to 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 blinking) and nothing is printed.
If the RECEIPT OUT or JOURNAL OUT light is on, a paper roll is not
installed or is at or near the end. Install a new paper roll. See
Chapter 1 for instructions.
If the RECEIPT OUT and JOURNAL OUT lights are off, make sure
that the printer cover is properly closed. Press the round
indentation on the printer cover until the cover audibly clicks into
place. You may not be able to close the printer cover if one or both
of the OPEN <-> LOCK levers is open. See the illustration on page
3-6 to help you close the levers.
