Welcome to HP support community.

Did you make a copy and check if that prints fine?

Meanwhile:

If that does not copies fine, follow the below steps:

Check the ink delivery system

1. Make sure the transportation ink valve is in the unlocked position.

      CAUTION: 

   Printing with a locked transportation ink valve can damage the printheads.

   

2. Make sure the printer is turned on.

3. Inspect the position of the blue printhead latch.

   1. Open the exterior door.

   2. Open the printhead access door.

      

   3. Wait until the carriage is idle and silent before you continue.

   4. Visually inspect the printhead latch position.

      • If the printhead latch is closed, continue to the next step.

      • If the printhead latch is open, skip to Replace the printheads.

         CAUTION: 

      Do not touch the blue printhead latch! Touching the latch might open the carriage and cause damage to the ink system.

       

      

4. Reach inside the printer through the printhead access door, and then manually move the carriage to the right.

   

5. Visually inspect the ink delivery tubes.

   • If the tubes are white or ink stained, the printer is not properly primed or out of ink, skip to Replace the printheads.

     

     

   • If the tubes are completely filled with dark ink, the printer is properly primed and filled with ink, continue to the next step.
