Just had the paper pickups replaced on my 8570, now pages have splotches all over them and cleaning results in 93,984.00 errors. Cleaning just fills up the overflow tray. I suspect the tech had the printer on it's side while replacing the pickups. I've taken off the side covers and and taken out the ink loader and it looks fine to me. I can't see any spills or anything. Didn't go so far as to remove the printhead though. Any tips?
