I have inherited an issue form another tech (while he was on vacation) and am beginning to pull out my hair on this one. Perhaps I can't see the forest for the trees, but here goes.
Customer calls in an issue with tray 1 jamming. When I arrive, they indicate this machine has had long time ongoing issues with jamming when using tray 1. Not only that but this unit had moved to this location earlier in the year and had been having issues even before the move. So I know no less than two other techs have either ignored the issue or failed to resolve it.
Symptom: When using tray 1, loaded with plain letter size paper, the machine picks up paper, correctly registers an image on it and stops part way through the fuser. The unit is logging Jam 009, External Tray.
This only occurs with tray 1, the other trays work just fine and I even tried them with different sizes and orientations where possible. So, despite the error being logged in the exit area since it only occurs with tray 1 I begin to investigate tray 1 for issues. I did find issues that were rectified such as a bent lifter in the tray, and dislodged paper stack height sensor. The unit had new feed rollers, so I tried the torque limiter also to no joy. When these machines were new I recalled having a misbehaving machine where I had to replace the feed unit for tray 1, so I thought it was worth a try. I also replaced the registration clutch and feed clutches while in there, still no luck.
The paper stops in the same spot each time, suggestive of a sensor / electronic issue rather than a mechanical one, but still only with tray 1. Any suggestions? I'd think that the external tray sensor is alright, it checks out in Input check in SP mode and I can use any exit with the other trays just fine.
