Alright I have an Hp Designjet 8000, I had an error message that said sytem error 1290, I know that this is saying to replace the prime assembly, which I have done. It is still popping up this error message when I start the printer again. I think I need to reset the counter, but have no clue of how to do that. Any help would be greatly appreciated, with this machine down, so is our production.
