printer failure

[Parkex]

My HP Office Jet Pro 6978 stopped printing. It keeps giving me printer failure message but first it displayed an error message that my cartridge was empty (in fact its full). I cleaned the drawer and realigned the paper. Now it won't print. Need help to resolve this problem.

Welcome to the HP support community.

I understand that you are getting printer failure,  I am glad to assist you.

Check for obstructions in the carriage path

Clear obstructions from the carriage area inside the printer.

1. With the printer on, disconnect the power cord from the rear of the printer.

2. Open the door to access the carriage inside of the printer.

3. Look in the carriage path for debris such as crumpled paper or dislodged labels, and then remove any that you find.

   

4. Use your hand to move the carriage to each side, making sure it moves freely. If the carriage is stalled or docked to one side of the printer and you cannot move it, continue with these steps.

   

5. Close the carriage access door.

6. Reconnect the power cord to the rear of the printer, and then turn the printer on.

Reset the printer

Reset the printer to recover from printer failures.

1. With the printer turned on, disconnect the power cord from the printer.

2. Unplug the power cord from the power source.

3. Wait 60 seconds.

4. Reconnect the power cord to a wall outlet and to the printer.

5. NOTE: HP recommends plugging the printer directly into a wall outlet.
