My Sharp AR M550N reported a misfeed. My employee removed the misfed papers (none ripping) Didn't resolve the issue. I went over and looked for any small pieces of paper with a flashlight couldn't see any. I restarted my printer hoping that might just reset it. One of the "arrow indicators" where the screen says the misfed papers are, moved but nothing else. I check and rechecked a dozen times. Then I went out and got a can of air and "sprayed down" copier hoping to blow away any small pieces of paper by the sensors, restarted the printer again and no luck. What do I do now? Just replaced the upper fuser roller this morning and had the drum replaced about a week ago. Pretty sure that last bit's not meritable information but what the heck.
