No short cuts.
I keep rebuilt SRDF2's in the shop and just swap them out.
It is not a job I would want to do in the field. ( it would be nice not to include in contract since these are aging problems. the rollers I replace are all dry-rotted ).
I replace registration roller and lower conveying roller at the same time plus I do all feed rollers and check one way bearings.
It takes me a couple of hours or longer per doc feeder.
I have done 6 or so thus far and I do not see a fast way to replace them since so much is built around them.
If you figure something out that is faster, Please share...
Perhaps I will take pictures and share on next tear down.
Thanks for taking the time to respond, I havnt done it yet, but about to...Originally Posted by kjg
which are the two rollers you are referring. could you elaborate or give a part number ?
repaired quite a number of those in years gone by and don't recall having to replace rollers other than the pup,feed and sep . Yes, you have to clean the rest thoroughly as they get very dirty with black stuff buildup. the job is not difficult, just a little bit of work to get to the separation roller. and you have to clean and lube the one way bearings and the brass bushings.

Could you mean the Mita RADFII ... like from the 90's, on the DC-5585? Those machines should have been recycled a decade ago. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I think he is referring to the kyocera falcon2 option SRADF2 doc feeder. This is a perfect case as someone trying to figure out what the poster really referring to. a simple inclusion of the exact model number would have eliminated blackcat wondering.

I took a guess and thought it was a SRDF-2 which you see on Falcon 1's and 2's.
The rollers that dry rot, get sticky, and shrink are:
the registration roller (3BC08050) and
the lower conveying roller (3AL08112)
They are a royal pain to install. But we still have a few out and it is necessary to replace
when they get bad. They jam quite a bit at registration due to the rollers being smaller than
they should be. They get real soft and can fall off the shaft. you can stick your screwdriver right into them to the shaft when they are bad.
Here is a bad photo I took a while back. New roller next to old roller.
I have another one to do soon, so if you want photos - I might post.
Thank you Blackcat for giving me flashbacks of working on 5585's and RADF2's.
I will now need more therapy sessions to recover.
(just kidding)
Have a great weekend!!!!
Is this like the neoprene rollers on the Canon RDFI and RDFII that turn into black chewing gum? You can avoid having this happen, by using only water based cleaners like glass cleaner on neoprene rollers. Oil or petroleum based cleaners absorb into the neoprene and accelerate their degradation.
Whew! Remember those moving belt feeders? We had modified the hell out of them. Doubled up and weighted pickups, neoprene registration idlers, different white belts... even then they didn't feed very reliably. =^..^=

I agree with Blackcat on cleaners.
Glass cleaner works very well.
I also think just a mixture of lanolin based hand soap and water does a good job.
No harsh cleaners as these may tack up the roller in the short run but will break it down over time.
The rollers in question in this thread will just break down naturally over the years.
