Re: Is the separation roller in feeders supposed to spin backwards?

So I checked out the feeders on a 2550 and c2800. Similar feeders to the c3503.

When spinning the gear that the separation roller is on, the 2550 and c2800 did spin. On both of the c3503 they do not. So... I took it apart.

This is what I found. There is no pin, no glue, no nothing, that could spin the sep roller. WTF?

Similar but not the same. Judging from the service manual for the feeder, there is no pin. It uses a single D type shaft end. Single D nylon, delron and other plastic gears will eventual round out.

This is the end of the shaft where it fits in the gear. Am I missing something? Is it supposed to be glued or something?

Do you know the product code for the feeder, D683 or D779? If it is D683 the gear should look like attached.single D gear.jpg

I'm sure theres a ricoh bulletin regarding double feeding and it's to do with a separation pad just before the sep roller.

That bulletin refers to SPDF only.

I was about the glue the gear on. lol. Then I noticed the pin in the white bushing. This shaft does NOT turn. The sep roller in this particular feeder does not, and never did spin backwards. It operates more like a separation pad.

See, the problem I had in this particular feeder was that it would feed great with 50 sheets, but once it got down to the last 7-10 pages, one of the pages would skip through un-scanned. So if you were to scan, say 17 pages, it would say it scanned 16, and looking at the pdf, it did skip a page. It would then work fine for a couple weeks. then start skipping pages. Ghosting the pages, no error or anything.

I just put a piece of cardboard under the "friction pad". Works fine now.

Lol it will just wear down and get a bald spot. You don't have that part on your feeder so that's definitely that

Re: Is the separation roller in feeders supposed to spin backwards?

I have had trouble with the SPDF double feeding....Remove the reverse roller (2241) from the hub and put a AF032080 blue reverse roller on that black hub. This has resolved my issues completely.
