[Jamming] Ricoh MP 6001 ADF misfeeds

[Blu's Master]

Good Morning; I have a Ricoh MP 6001 that randomly misfeeds. I have replaced the feed belt, feed roller, and the separation roller. Also i have cleaned all of the sensors in the original feed path. Does the MP 6001 ADF have a known issue with random misfeeding?

Thanks, for any help that you can provide.

Have you also replaced the torque limiter?

Had this once.
Client had broken a part by brutally closing the DF.
This is what I had replaced then (and solved it):

Thanks, Ill check/replace the torque limiter next. The ADF doesn't appear to have been damaged.

You must look carefully to see the crack, I believe it was on the rear side of a guide or so...
long time ago!!!

Thanks, I'm going back today,and will take my time, and check everything.

You might also want to check/clean/replace the one-way bearings. Is it the same jam code when it jams or does it vary? What is the jam code?

These can be a pain in the ass, I vote for the one way clutches too and the shafts.

yes the one way gears on these mp6001 doc feeders need to be cleaned quite often. clean the bearings with alcohol and clean the shafts lightly with emery cloth or scotch brite. pay close attention to which way the gear is on. its very easy to reinstall backwards! there are 5 or so one ways in the gear pack on this one.

What is the jam code? Are you sure you got to all of the sensors?

Re: Ricoh MP 6001 ADF misfeeds

Thanks for all the replies. I apologize for the slow response to your messages. The jam codes are always 003 and 004. I can scan using the document server function as a test and get no jams. Does that make a difference as opposed to the copy function? I don't have a new torque limiter right now or I would try that to see if it helps.

Thanks to all!

The bypass torque limiter is the same as the ADF one. Try swapping them.

Re: Ricoh MP 6001 ADF misfeeds

OK, thanks. I try that.

Re: Ricoh MP 6001 ADF misfeeds

Funny the 6002 has the opposite problem. Copies would scan all day, but scans would randomly jam. There was a bulletin on the 6001 jamming at the white belt over the slit glass. Lube the idle pulleys, but I don't think that was a J003. It would mangle the originals big time.

Re: Ricoh MP 6001 ADF misfeeds

Thanks, the ADF that I'm having this problem with doesn't mangle the original, but the original does stop at the white roller. Are you talking about the feed belt drive roller? I'm not sure which pulley you are talking about. The feed belt drive roller is the white roller with the one-way bearing that the feed belt runs over. Thanks for you time.
