mp4000 mp4001 mp4002 cleaning web not rolled-up

[Mark Bbb]

Sometimes the cleaning web is not rolled up and so causing jams.
If this happens I can manually roll up the web by turning the "worm-gear" ...
Is this "not rolling up" issue caused by the machine or due to the cleaning web ass'y itself?
Thank you for your help....

the orange oiler roller has unidirectional ones that lock and cause this.also when the client sends very much loaded documents of toner sticks and does not let the web advance

Re: mp4000 mp4001 mp4002 cleaning web not rolled-up

I always referbish these myself.
There are four "one way gears" in the ass'y,
that is why i think the problem is due to the ass'y and not due to the machine itself...
So, we are now forced to replace the ass'y unit, because Ricoh doesn't offer one of these "one way's" anymore:
D0094355 roller clutch
Those modif web's are almost impossible to referbish.
I have tried this and failed.
Does anyone know where you can order D0094355?

If you are an authorized technician with either a Ricoh direct branch or RFG dealer you can obtain the bulletin from either tsrc or rfg-esource. Technical Service Bulletin D129/D130 – 012 REISSUE

those unidirectionals I put them in varsol or other mild solvents


Once they are already without rust and gobs, dry them well, I put a few drops of silicone oil and return to work full

They have updated the "brake system" for these webs. Instead of the one-way bushing for the orange roller, they changed to a ratchet-style system, and added a plate that helps keep the web tight and from unfurling. Orange roller has been updated also to accommodate the new "bushing".
You can also just remove the web unit from the fuser, and let the machine run without it, still gets pretty damn close to expected yield.

We don't even bother changing webs any more.
We only use the printer maintenance kits on these machines...A kit for the PCDU and the B kit for the fuser and transfer.
Hardly ever have webs run out these days as they seem to last the life of the maintenance kit fuser since it's rated lower than the copier parts.
It's the SP820dn kits if anyone is interested.

if you change the developer and clean the mag roller around 100k, the pm can stretch to over 200k on this model. the web only goes 150k reliably, so the web cruises and keeps the fuser in great shape along the way. This is a difficult model to get, but it works.

hello to everyone, I had some cleaning unit that unrolls and caused jams, then I discovered that the problem was mainly caused by two things, the worm gear that sometimes did not match well with underlying gear and unidirectional bearings (especially that of the orange roller) that turned in both directions, with regard to the worm gear I slightly ovalize the right hole with a small file for the iron, so that it is possible to push slightly down to better match the worm gear with the gear below,
the unidirectional bearings clean them all well with rag, screwdriver, and alcohol, then I mount them dry, and test them well

I tend to find these models will run with the webb unit NOT installed (as long as your not doing long runs with heavy coverage they will work).

Cheers

the purpose of the cleaning web is to clean the fuser roller. WHY in the world would you NOT put in a part that a DESIGN ENGINEER got paid to design and incorporate into the machine?
Running without a cleaning web will cause PQ/CQ issues
