To resolve problems with the power supply:

1.Remove the printer from any UPS supplies, additional power supplies, or power strips. Plug the printer into a wall outlet and see if this resolves the problem.

2.If the printer is already plugged into a wall outlet, try another power source in the building that is independent of the one currently being used.

The line voltage and current source at the printer location might need to be inspected to ensure that they meet the electrical specifications for the printer. (See Electrical specifications.)
