It's a KM-8000i that started out with J4913 jams. When it first started it would jam once or twice, then print several thousand. I seems to be getting worser and worser. It will no longer pass any paper.
Early on (3.5M prints), I had changed the conveying rollers, paper feed flags & springs, and decurl roller. Today I changed all the photointerrupters in the bridge. When I arrived there was a J4914 jam that would not clear. After changing the sensors I got C1410 and J0132 jams (de-curl rotation error). If I go into U031, BRSW2 will randomly appear blocked or unblocked. Just to be sure, I installed 3 more photointerrupters with the same result.
So I've got all three sensors in the bridge randomly changing state. It's possible, of course, that the engine board is bad but I'm leaning towards the bridge controller as the culprit. It's the randomness that bothers me. Has anyone seen something like this?
