MP 2500 jamming

[TCA TECH]

I am getting a OFF-Regist Nofeed A4 paper jam code on a MP2500. I have yet to see it jam but the history is totally infected with them. Can not yet tell you which tray it is.
Machine has only done 50k
Anyone have any ideas, the technology is the same as MP2000 but it has tray lifters in it.

I'd check paper guides, feed rollers etc. If it doesn't happen while you're there, likely the customer isn't giving you all the details. Any jams removed left in the garbage can? The trash can be an invaluable tool at times.

Defective registration clutch? I've seen a machine jamming only the first few copies in the morning.

There is a Plastic Piece (sry, i dont know how to spell it better) at the backside of the mashine, that fits into the lifting shaft of the cassette, check if it is broken, have seen it several times.

Take it out to look at it also, it might just be a hairline crack that only shows under the stress of lifting the tray. Good call on that one.

I am having th esame problem, Any other ideas what may cause this problem. There is not customer error for definite..

Many thanks

Re: MP 2500 jamming

I also agree with herrmann and cobiray that the Rising Unit is most likely the culprit with a crack in the chuck (part #B2092780).
Another possibility - does the misfeeds seem to occur when the paper tray level is low? The combination of height sensors and paper width tell the device to add more pressure when the paper level is low for smaller width paper. Make sure those are all in place and functioning. Attached is the detailed descriptions of how the feed mechanism works.

Re: MP 2500 jamming

2 suggestion from experience with similar problems.

1, if the machine has a bridge unit, there is a problem with the door switches on the bridge units on this series of machines ( mp 2500, 4000, 5000, ect...) and per the bulletin it wont log alot of the jams.

2, on this machine there is a flat plastic peg on the rite side door that presses the door switch, due to the door are flimsy and flex when u close them the peg gets bent outa shape and broken, causing the machine to randomly think the door is open during the copy process.

Re: MP 2500 jamming

Thanks guys,
I actually tightened the screw in cassette on lifter shaft, cleaned every thing and in 5K no jams. I really think it was the paper
;-(
But what a complex lift system, can't wieght till they are old

Re: MP 2500 jamming

I have a Savin 7025 (Ricoh MP2500) that has given us fits for a very long time now. Intermittently decides to say it has a jam in B and nothing has even left the paper tray. We have replaced paper feed roller, friction pad, all feed, relay, registration clutches. It seems to work after a call for a couple weeks then go back to this symptom. Is there a good chance that the lift mechanism may be the issue? Can anyone name specific part numbers or names that I'm looking at? I must get this figured out. This machine only has 38K on it. It states jam code 10 on the SMC report, but shows code 17 for whatever reason in the jam history.

You'll get a better response if you start a new thread, but try unplugging the lift height sensors on the back of the lift arm for the offending tray. If you watch the tray go up after closing you'll likely see it go up and then down and then back up. The issue I've had is that it doesn't always go back up to the feed roller after it goes down. I've been unplugging those sensors as soon as I get a whiff of this problem. I assume the machine then uses just the paper empty sensor to lift the paper trays after these are unplugged. Open the side door and peak into the feed area as you close the tray to observe and confirm this is the issue you're having. If you add or remove paper this usually solves the issue temporarily.

You can also try firmware, but the last time I had this issue the firmware didn't resolve it.

Re: MP 2500 jamming

I had found my problem which was two copper bushings where reg clutch and feed clutch is. They have been fitted other way round so occasionally not feeding the paper. Check parts catalog to make sure which way they need to be fitted in.

It must have happened during manufacturing process so that why we had so many issues.

your attachment like for others model(MP2000)..For MP2500 the paper feed totally different

Re: MP 2500 jamming

Check the hooks on the vertical transport door which latch it to the main body. I had one where the tip of the front hook was missing and the door was moving away, allowing the door switch to open as the paper hit the reg roller causing "B" jams. Not obvious with the duplex unit closed.

look again, straight from the D010 manual (MP2500).
