I've got a Bizhub C450 that will start out at 17" long (on 12x18) and after about 50 copies the image grows to 17-1/4". Fuser transport speed is not turned up, sensors are clean, I exchanged the vertical transport and still she grows on both sides. Don't know if it would continue as I have only run 75 or so.

Did the image get larger or did the paper shrink?

Are these 50 copies of one original? If it's one original you've ruled out the document feeder. If multiple originals, you may have a drive problem in the DF.

Is it only stretched in the feed direction? If yes, it sounds like drive speed varying. Maybe fuser speed, maybe primary transfer belt speed. I
If no, ... well I can't think of a situation in which the size would vary in both the feed and crossfeed directions. =^..^=

Sorry, should have given more details. These are printed copies of one 2-page file, not off the glass. Yes, the image stretched, not the paper shrunk. I've got a big hammer in the car . . .

Image belt would have to slow down or paper speed up. I'll change the belt and experiment some more.

Fuser loop sensor stuck on?
