KM-3232 Paper feed problem

[selig67]

From tray 2 only (it doesnt have a drawer base). It will feed 11x17 and 81/2X11R. but not 81/2X11. It stops just as it passes the first feed sensor. The sensor works (although I still changed it out). I have replaced the drive section for the feed and the feed board and the engine board. I have reset the machine to factory default, initialized the memory, formated the hard drive.

what could it be????

OH, and can some one tell me how the rep power works, and why is mine so bad??

What jam code?

If its J18, have you tried installing the new style pressure springs (302FZ04763) for the lower left door pressure rollers. They come from the factory with one spring per shaft. I've been known to install two or three springs per shaft.

I thought of that.. but it feeds all other sizes and I have pressed on the door as it was running.

The paper doesnt slip, the machine just stops feeding as if the first sensor isnt detecting the paper. All drive motors stop.
