Ricoh 8001sp

[Old Crow]

Tandem drawer jams at reg. rollers and kicks down B2 guide plate. Removed feed unit and cleaned one way bearings and shafts and replaced p/f/s rollers, no help. Cleaned all rely/transport rollers, one ways and sensors. Drawers two and three feed fine. Played around with guide plates at reg.rollers, seem to remember this caused similar problem on a mp5500. Any help appreciated, going back tomorrow. This customer has little patience! Thanks...

Re: Ricoh 8001sp

Try swapping the first feed unit with one of the other trays. If the problem moves with the feed unit, the problem is in the feed unit.

You did not tell us what the jam code was. This is the first thing to know when trying to fix jamming. If it is a one way gear, TSB 018r has a table that will tell which one to replace base on the jam code (8,9,10, and 12). If it is a J53, replace the torque limiter.

Re: Ricoh 8001sp

Thanks for the reply, the majority of the jams codes are 12. I guess I wasn't thinking straight as it never occured to me to swap the unit. I can't find that technical bulletin anywhere, there is a TSB18 but I have seen 018r. Any chance of getting that from you somehow?? Thank again.

Re: Ricoh 8001sp

You have cleaned all the paper dust that's probably covering the reg sensor that's under the metal plate under the dev unit right?

Re: Ricoh 8001sp

Yes and there was a lot of it. Cleaned reg rollers also. Again, drawers 2 and 3 work ok.

Re: Ricoh 8001sp

Are you leaking Developer? If so, replace all one-ways in feadhead.

Re: Ricoh 8001sp

No dv leaking. Does replacing all one way bearings usually cure that? How about sensors too?

Re: Ricoh 8001sp

Check the vertical plate. Make sure the relay rollers have enough pressure to feed the paper.Had it a few times now where the plate was warped or the locking mechanism was bent.If memory serves me well there are two sets. The top may be ok but the bottom once not.

Re: Ricoh 8001sp

Are you talking about the metal guide plates with mylar strips on them? They look ok, I tried forming them one way then the other. The lead edge of the paper gets into the nip of the reg rollers so if you turn the rollers the paper advances forward evenly.

Re: Ricoh 8001sp

What's the condition of gears anyway?
Happened more than once that waste toner bottle sensors fail and owerflow on pick-up gears.

Re: Ricoh 8001sp

Jam 12 from tray 1 is the smaller of the two gears that are on the same shaft. New part number AB011491.

Re: Ricoh 8001sp

The gears don't look dirty from toner or dv, but machine does have 1.1 mil on it. Thanks for the part number, do you think I should replace others also? Thanks for all the replies.

One way rollers of the gears just get worn out after a while. 1.1 mil is about where the first relay clutch on the Aficio 550s and 700s would have to be replaced. Same symptom, late jam at the registration sensor.

Re: Ricoh 8001sp

I'll replace all of the one ways and the relay cl. thanks again for all the help!

Re: Ricoh 8001sp

just a follow up to this problem. I replaced all of the guide plates with mylars and this did the trick. I guess the paper fed ok from drawers two and three because the paper is coming straight when the lead edge hits the reg rollers as opposed to coming from an angle from the top feed unit. thanks for all the ideas and suggestions with this problem.
