    During my initial diagnosis, it seemed like the belt was the cause but I couldn't see it, so couldn't confirm until I pulled the panel off to verify. I was actually surprised to see that there was nothing to hold the belt onto the drive gear. The motor assembly on the other side actually has a small black plastic disk that prevents the belt on that side from jumping off, not sure why they wouldn't have done the same for both.

    Being as resourceful as I could be with what I had on hand, I installed a flat plastic protection disc that is used on the mag roller of BH223 style development units. They come as part of the DS Roll Kit to protect the bearings from toner and developer. It's flimsy, doesn't fit all the snugly on the gear shaft, but I'm hopeful that it will prevent the belt from jumping off again.
    i used to carry a small tin of all sized plastic washers... easy to hollow out for a shaft.

    I had to go back over to the same place again and that's exactly what I did, but put a metal washer on it to help keep the belt from coming off. BUT, the whole issue with the one I've been dealing with is that the tracks get so dirty that they cause the rollers to bind up and get caught on the feed side, right before the fingers come around on top. So if there is binding on the fingers movement, the belt coming off probably saves stuff from getting broken, I'm guessing.

    Another possibility that I thought of after leaving the call the other day was that maybe the customer is grabbing the exiting stack of sheets before the eject system has completed its job of moving the stack to the tray. Maybe they shove in on it and it causes the fingers to bind, thereby causing the whole C1105 thing and possibly the belt coming off. No way to know for sure because nobody ever fesses up to stuff like that.

    Put a sheet on top cover " PLEASE let the paper finish exiting the finisher before grabbing it, this is the cause of our problems " then go to the HDIC and give him/her a copy of it.
    Usually fixes the problem really quick. You might also the next call for this problem WILL be a charge call.
    Hit em where it HURTS!

    I'm totally with you on that except I have no way to prove that's what's happening. I sometimes wish we could put little pinhole cameras in the machines to catch stuff like this but that opens up a whole can of worms related to privacy concerns.
