Perform a Power Reset to see if it helps:

Power Reset to eliminate a possible logic or power issue:
1) First, make sure the printer is plugged straight into a wall outlet and not a power strip, surge protector or UPS.
2) With the printer plugged in and powered ON, disconnect the power cord from the printer. This will hopefully dissipate any electricity stored in the printer that could be causing a problem.
3) Wait at least 30, preferably 60 seconds.
4) If you don't have an actual ON/OFF switch, press and hold the power button for about 10-15 seconds a couple of times in the beginning just to be sure it tries to drain the power fully. Make sure any other cables, other than power, are removed when you try to power it up again.
5) If there is a power switch, turn it to the OFF position.
6) Plug the power cable back into the printer.
7) Turn the printer ON with the power switch.
