Hi. Our printer is not printing. It started out with yellow needing to be replaced. Then blue indicator. Other levels were fine, yet after ink was replaced, the printer is still not printing. Magenta was low so I replaced it as well as the black. So now there are all new ink cartridges, but it still is printing blank sheets of paper. I cleaned the printhead as well. Thanks!
Remove printhead and let it sit in a window cleaning solution and warm water mix 50/50. See video on how to remove printhead:
Remove all inks, then the printhead & sit the printhead on a soft cloth soaked in warm water - let it sit for a few minutes then reinstall, close lid then make the machine ask for the inks once the inks have then been installed it should prime the machine. If this does not work try it again & if that fails then your printhead probably needs to be replaced.

Hi Jan,
Can you confirm that you are using a CIS or non-HP cartridges with this printer?
It sounds a lot like the printhead has reached a clogging point where sediment has built up in the black portion and loosens enough to printer a few lines before it re-asserts itself again.
Based on my experience of this printer, if you're using a non-HP delivery system for ink then you should consider replacing the black ink with a dyebase alternative instead of pigment.. Replacing the Black/Yellow printhead and running a number of test prints to purge the pigment ink in the printhead should then result in a clean and more reliable printout in future.
One other vector for problems is the cleaning area and I've found that this can become soiled with excess ink causing cross contamination within the inks of one printhead. As yet I've not found a reliable solution to counter this sort of issue.
Hope this gives some clues and hopefully some ideas of a fix.

Many thanks for the suggestions received. Have been told by HP to
change the black printhead - which has solved the problem!

Same thing happened to my printer hp L7590. Printed diagnostic, only black and yellow printed; diagnostic for printhead health Ky=good, MC= good. Only Hp products ever used. Uplugged, & discharged static, cleaned copper parts of printhead. Still no fix. On visual examination of floor of printhead compartment rectangular pad ( approx 1/4" by 1/2") is missing. I can only guess that during the paper jam, somehow the pad got caught up and went awol. Not sure what to do now.
CAUTION:
Do not place anything on the transfer belt (ETB), which is located on the
inside of the front door.
