Troubleshooting
This chapter gives solutions to some printer problems you may
have.
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
An ERROR light is blinking and the printer does not print.
First, turn off the printer and check for a paper jam. (See the paper
jam description on page 3-3.)
If there is no paper jam, turn off the printer and turn it back on after
about 10 seconds. If the ERROR light is still flashing, contact a
qualified service person.
The ERROR light is off, but nothing is printed.
Try to run the self test to check that the printer works properly. See
the self test instructions in Chapter 1 to run the self test. If the self
test does not work, contact your dealer or a qualified service
person.
