What is the thinking behind the shaking? I should say that this printer is used pretty much every day, I have an all service plot from Jan this year that shows 934944 cycles of component usage including the trailing cable, is this a lot? I seem to remember seeing an HP document listing the predicted service life of various components but I forget where.
William.
If you shake the Print Heads, it stirs the inks up and helps to clear blockages. I don't know about the predicted service life.
After thinking about it, William, I'll bet you've got a bad carriage PCA. Often this will be the cause of the printer rejecting print heads.
Again, check all the connections first, then I'd look into getting a carriage PCA.
You can get an OEM replacement for $67.72 >
HEREPretty sure that's what's going on, but of course without being there to see it, I could be wrong.
It's something you can replace yourself.

William - here is an HP document that details a procedure that you could try first, before getting the PCA board.
HP DOCUMENTIf you have removed all the printheads as they discuss (even though the document is for the Z6100, it is still pertinent),
then perhaps move on to the PCA board....
