Welcome to HP Forums, 

This is a great place to get support, find answers and tips to your technical queries.

To provide you with an accurate solution, I'll need a few more details:

Any hardware changes made in the printer?

Did you try to print from a different application?

I suggest you do a Hard Reset

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Align the printer from the HP software.

1. Open or search for the HP folder in your list of installed software applications, click the folder for your printer, and then click the name of your printer.

   HP Printer Assistant opens.

2. On the HP Printer Assistant window, click Maintain Your Printer.

3. Click the Device Services tab, and then click Align Cartridges.

   The printer prints an alignment page.

4. Lift the scanner lid.

5. Place the alignment page with the print side down on the right-front corner of the scanner glass, and then close the scanner lid. Position it according to the guides around the scanner glass.

   

6. Close the scanner lid.

7. On your computer, click Scan.

   The printer aligns the printheads.

8. Recycle or discard the alignment page.
