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.
Martin
