So, in order to fully understand this situation, you would need to do a Bongo test (see in repair manual).
That is a real pain to do and requires at least 1/2-3/4 or full cartridges.
If it was mine, I'd try to find the details about the error message.
I can't remember exactly, but if after the error message, you press menu and up arrow at the same time, you will get an explanation further of the arrow message.
You'll probably have to go to the repair manual to find the right button combination, so do your homework.
My experience tells me that you might possibly have a print mech board gone bad.
If you come to the same conclusion, buy a new oem print mech board from HP or a HP reseller. If replacing the print mech board doesn't work, you can call HP and they should give you technical support relating to the print mech board and your issue.
When you get into IS errors, I'm not that up on repairs for that, so possibly Ernst Dinkla might see this and give suggestions as he knows more about this than I do.
I've been fortunate not to have had to replace any ink lines, even though I know how to do it.
I recommend finding out further what button combination to push to find out how to read into the error message.
Best,
Mark
