Our 7550 was having trouble pulling pages through so I replaced the rollers. Now it won't pull them at all. It starts to, then it sounds like the page is getting stuck on something, possibly the retard rollers, then I get the message that No page was found in the feeder with the error code -4401. I've checked all the rollers, I've cleaned all the glass and sensors, I've tried the count only trick (same thing). The tray rises, it starts to pull the paper, the paper shakes sometimes, then it just gives up. Any ideas?
