Check the power source the printer is plugged into:

Plug the printer directly into another, known-to-be-good, wall outlet as a test. If too many devices are using one circuit breaker, temporary brownouts can occur at the printer. For testing purposes, do not plug the printer into a surge protector, power strip or uninterruptable power supply (UPS). If the power-up problem only occurs when the printer is plugged into the surge protector, power strip, UPS or one specific outlet, then the problem is with that device or outlet. Also make sure that both ends of the power cord are plugged in all the way.

If the printer started power cycling (powering OFF and ON) after a power surge from an electrical storm or a power outage, power OFF the printer and unplug the printer for at least one minute. When this time has elapsed, plug the printer into a stable power source and then power ON. If the printer still does not power up properly, service will be required.

NOTE: Make sure the power source is valid and stable, and if possible, monitor the line voltage. Avoid plugging the printer into a UPS (uninterruptable power supply or surge protector), especially if unsure of the power rating.

Isolate the printer:

Networks and peripheral devices can cause a wide range of unusual symptoms. To verify that the problem you are experiencing is not being caused by the printer, perform the following steps:

  1. Power OFF the printer.
  2. Disconnect all cables from the back of the printer, except for the power cord.
  3. Power ON the printer.
  4. If the printer does power ON properly, power OFF, plug in one of the cables, and then power ON. If the printer does not power ON properly the problem is with the cable, network or peripheral.
  5. Repeat this process of elimination with the other cables to determine the source of the printer not powering ON properly.
  6. If problem persists, service will be required.
