My problem was that my Sharp AR-M162 printer could print out one page, exactly, before jamming (if there was a 2nd page coming) and then issuing a “Clear Paper Path” error. The display indicates the error is from the side panel. However, unless the 2nd page was stuck when the Clear Paper Path error came up, no paper is stuck there.
I had worried that either there was a small piece of paper stuck somewhere deep in the mechanism, or else that a part was failing. I had gone through all the directions available online, such as the fixya forum. I had even unscrewed another panel, blown compressed air everywhere sensible, and so on. Still the problem remained. I could clear the error by opening and closing the right side panel, but as soon as another page printed, the same error would occur.
Fortunately, the technician was the sort of man who should fulfill that role. He was helpful, friendly, informative, and very competent. The used his experience with the copier to rapidly diagnose the problem, fix it, and test it.
When the “Clear Paper Path” error reliably comes up on the Sharm ARM162 after one page has printed, the problem is most commonly with a small plastic arm insdie the right side panel. The plastic arm may become dislodged during a paper jam, during moving, or oher jostling. The solution is to gently force the small plastic arm in place. The reason this causes the error is that the very right end of the plastic arm tells a sensor the previous page printed OK. If the arm is bent or partially dislodged, the arm’s end is not where it is expected to be, and so the “Clear Paper Path” error is flagged. Opening and closing the right side door temporarily fixes the error because the motion of the side door opening and closing will often (about 50% of the time) temporarily move the arm’s end into place.
Of course, no one is ever happy about having tech support come out (or receiving the bill!). Still, I am happy no new part is needed, and that the problem is anything I “missed.” The problem was an unknown unknown, something I did not know what wrong that I was not even looking for. I now know more about my printer, and (thanks to BBE’s great technician) will be able to solve a similar problem in the future.
