6. Under ECM you will have to options "ON or OFF" try to choose OFF then press OKAY.

Also you can try to reset the printer.

2. Make sure the unit is connected to the wall jack directly without any surge protector.
3. Unplug the power cord from the back of the unit ( without turning off the unit ) .
4. Now press the # and 6 key together , while holding these keys down plug in the power cord back into the unit .
5. Do not release the keys after a few seconds you will find the hp logo or bars moving across the screen .wait while the unit turns off.
