Troubleshooting. Power-on checks

The basic printer functions should start up when the printer is connected to an electrical outlet and the power switch is pushed to the on position. If the printer does not start, use the information in this section to isolate and solve the problem.

If the control panel display remains blank, random patterns display, or asterisks remain on the control-panel display, perform power-on checks to find the cause of the problem.

Power-on troubleshooting overview

During normal operation, a cooling fan begins to spin briefly after the printer power is turned on. Place your hand over the vents at the rear of the printer, next to the formatter, or on the on the rear of the scanner. If the fan is operating, you will feel air passing out of the printer. You can lean close to the printer and hear the fan operating.

A fan begins to blow on the right door (fuser), and then the control panel goes through a series of set up functions. The main motor turns on (unless the left door or cartridge access door is open, a jam condition is sensed, or the paper-path sensors are damaged). You might be able to visually and audibly determine if the main motor is turned on.

If the fan and main motor are operating correctly, the next troubleshooting step is to isolate print engine, formatter, and control panel problems.

If the control panel is blank one minute after turning on the printer, check the following items:

  1. Make sure that the printer is connected directly into an active electrical outlet (not a power strip) that delivers the correct voltage.
  2. Make sure that the power switch is in the on position, and then verify that the LED is on.
  3. Make sure that the fan runs briefly, which indicates that the power supply is operational.
  4. Depress the button on the back of the control panel to test the control panel functionality.
  5. Make sure that the control panel display wire harness is connected.
  6. Remove any external solutions, and then try to turn the printer on again.
