Had a call this morning that was as the title says, bizhub 287 jamming with 92-02 (of course the customer didn't mention the code when calling) and making a loud noise. They left the machine jammed since it wouldn't work for the current duplex job they were running.
I opened the right side door to turn the jam removal knob only to discover the belt was slipping. After further investigation, I noticed the gear that drives the duplexer was broken where the shaft is molded into a plastic piece. Click on the video link to see the broken part.

Some of you may remember the metal spacers that were supplied by Minolta back in the day for the rear of the paper cassettes of the bizhub 2510 series. They were little right angle pieces that we were supposed to stick onto the part of the tray that meets up with the paper lift arm. Well, instead of us buying those, I just made up a few dozen by using my bandsaw to cut up an old machine cover that would have been tossed anyway. I still had some of those in my toolbox and used a couple of them to reinforce the super thin (around only .8mm thick!) plastic that broke by super gluing them in place after roughing up the surfaces.
Then I decided to add another layer of plastic on top of those pieces to really make it break proof. I always carry leftover pieces of packing plastic pieces with me to use for gluing up stuff in a pinch.
All put back together in the machine and it will probably never break there again. Ran several 2-sided with no issues.
I posted this in case others might have the issue but also to any new techs out there; you might have to improv a little or a even LOT like I have over the years fixing copiers, hence the "morning at the improv" in the title. I've lost count of the times I've had to come up with a solution like this when I'm an hour or more away from the office and no parts are available there anyway.
