We've been working on a low volume KM-5050 with only 293,000 prints on it and could use some advice. A couple weeks ago, it started making some type of line and skew across the trail edge of all prints. There's 2 photos of the issue, one LT and one LTR. The problem is always in the exact same spot and it never repeats across the paper like a roller would. It also never jams. About 2 inches from the trail edge of each print, it leaves a thin darkened line and slightly skews the last 2 inches of the print. Even on blank prints, it leaves a gray line across the paper in that same spot.
It is not an optic issue as the internal prints have the same issue.
The drum unit, main charge, and fuser were replaced at 112,000 prints a few years ago. I've cleaned/checked over the units and they all look great and DV unit turns smoothly. The resist roller in the door looks like it turns normally. It prints the same from each tray also. It seems like a timing issue of some sort to me so I cleaned and checked the feed, resist clutches. Nothing I've done has made any difference at all.
Since, the issue is on the trail end, could it be that when the paper transitions to the fuser, the timing is off just a bit and it lags? I believe they upgraded the drive pack on this model to add a clutch to it, but you also have to upgrade the engine board. I don't know if that would help with this issue.
I have a few ideas for my next step, but would love to see what advice is out there. Thanks in advance.
