Basic Printer Problems

Some printer problems can be easily resolved. If a problem occurs with your printer, check each of the following:

The power cable is plugged into the printer and a properly grounded electrical outlet.

The printer is turned on.

The electrical outlet is not turned off at any switch or breaker.

Other electrical equipment plugged into the outlet are working.

Optional memory is properly installed.

If you have checked all of the above and still have a problem, turn off the printer, wait for 10 seconds, and then turn on the printer. This often fixes the problem.

Display Problems

After the printer is turned on, the display on the operator panel is blank, keeps showing Please wait..., or the back light is not lit.

Turn off the printer, wait for 10 seconds, and turn on the printer.

Self Test Message appears on the operator panel. When the test is completed, Ready to Print is displayed.

Menu settings changed from the operator panel have no effect.

Settings in the software program, the printer driver, or the printer utilities are overriding the settings made on the operator panel.
