I have a 3253 that was having some serious quality issues, pouring cyan/yellow toner onto the pages. I fixed this by replacing the high voltage board, but ever since I have had issues with jamming in the exit assembly (4211, 4901). It will pass paper (in any orientation) to the middle tray (not using the bridge/finisher), and it will pass paper in the LTR-R orientation, but when the paper is in LTR orientation passing through the bridge unit/finisher it intermittently jams. I thought I had solved it by replacing the exit assembly. When I ran U030, one of the exit motors made a rattling noise intermittently. I assume one motor is for passing paper through one path (to the bridge), and the other is to pass paper to the middle tray (job-separator). Anyway, due to the noise and circumstances, I came to the conclusion that one of the exit motors was going/went bad. I went back, replaced the entire exit assembly (both motors attached), and it started passing paper in either orientation. A few days later I returned to fix a random issue, and noticed the machine was jamming in LTR orientation again. I have yet to go back, as I do not have much of a plan of attack. Any help is appreciated. Again, the exit assembly did take care of it temporarily, so I do believe I was on the right path... maybe something at the board level is damaging the exit motor? We may try a new bridge unit next? I also swapped engine board/feed image board during my troubleshooting for my quality issue, but I have since tried going back to the originals with no change. Thanks for any help.
