Welcome to the HP support community.
Check the ink delivery system
-
Make sure the transportation ink valve is in the unlocked position.
CAUTION:
Printing with a locked transportation ink valve can damage the printheads.

-
Make sure the printer is turned on.
-
Inspect the position of the blue printhead latch.
-
Open the exterior door.
-
Open the printhead access door.

-
Wait until the carriage is idle and silent before you continue.
-
Visually inspect the printhead latch position.
-
Reach inside the printer through the printhead access door, and then manually move the carriage to the right.

-
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.
