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.

I really love to read and especially see threads like this. Great pictures and even video for new coming generations of YouTube copier techs. Thanks for sharing srvctec!

Like most if not all your posts, you don't even read the original post and therefore your response is moot. That's also why you've been on my ignore list for at least the last year but since you posted in a thread I started, I wanted to see what it said and wasn't surprised in the least.

Hi srvctec, thank you! It would take more technicians like you. We make this forum a better place to increase our experiences.

Well, so much for that idea. The super glue didn't hold which is why I prefer to use epoxy.

Customer called several days ago about the ADF jamming with no mention of a loud noise again. So, of course when I arrived today (couldn't get there due to weather the last couple days) they said "Oh, and it's making a loud noise and won't print." To which I replied "Is it jamming?". The customer: "Oh, I don't know, it just doesn't work." In my mind but really wanted to say out loud: "Why do people think details don't matter at all when describing an issue with their machine? You might as well just say "My machine needs service." and leave it at that if you're going to play the vague game."

Since I didn't know it had the same issue, I didn't have the spare part so I had to come up with another solution. I don't carry tin snips with me, so I had to use side cutters to cut out a piece of metal, after drilling a hole in it, to reinforce the part until I could replace it. This is what I came up with. I just bent the metal around the edges of the plastic to hold it all together. It's strictly a mechanical fix since I didn't bother with any super glue (wouldn't have held anyway). Looks horrible but not having the correct tools to do the job creates crappy looking results. BUT, it works!

We have a 227 in the shop and the part number is the same so I took it off and was surprised the older 227 has an all metal drive plate (like it should be). Not sure why a newer machine would have super thin, brittle plastic for such a crucial part. I'll put this one on next week when I go back up that way.

Saving $$$. If they build 1 million machines and they save on each machine
with that thin plastic "construction" 0.0005 $, that's........, WOW.....! 500 $!!
Lots of Shark Fin Soup can be bought for that...... :p
