MP 201 Side Door Knocking

**ABS tect** · 09-26-2016

I have had several problems with the MP 201's side door knocking...I always resolve this by simply replacing the side door. That's an easy fix but I would like to know what exactly is causing that knocking noise. I believe it has something to do with the transfer roller and the hooks holding it in, but just wanted to see if anyone else had run across this issue and has a better way of resolving it than switching the whole side door. Thanks!

Transfer roller bushing cracked on the front (gear) side. Very common

I have found that toner will build up in the bushings of the transfer roller assembly. If there is no obvious damage, try cleaning the bushings and shaft ends.

Awesome! Didn't even think about the bushings

This helps a lot...thanks to everyone!

I've noticed that an easy test is remove the gear from the transfer roller and the noise goes away then you know it is coming from there.
also it will run without the gear if you have to return with a new one at a later date.

When fitting a new transfer roller I put a spot of grease in the bushing, stops the break occurring in the first place. Also, a strategically positioned cable tie can close up the gap stopping the knock. Good stop-gap measure if you have to order one.

I Hope that you kept all those good side doors! Just fixing the transfer roller bushing will save you a fortune going forward!

B2623802 is the # I have for the transfer roller but I thought I saw somewhere that there is a updated (mod).

And do the bushing come with the transfer roller while I'm asking. I had a bunch of junkers that I have been pulling from but about to run out. Thanks!

If there has been an update, you should have received the updated part. That is as long as you ordered from Ricoh. And yes they come with the bushings.

The bushings and the shaft inside tend to draw toner and dust which can cause them to bind long before the PM cycle in a dirty machine/location. Remove the bushings from the roller and clean the shaft and inside of the bushings with a clean dry rag or shop towel. Take a picture first so you can be sure to get back it together properly.
