Vibration noise on MP C2551

[Ltd]

I followed Tech Bulletin, Replaced Fusing sleeve roller assembly, Adjusted down temperatures. 2 months later I had same vibration noise from right side again. Any body had solutions ?

I have this as a pending issue with Ricoh. No answers yet. sent them a fuser to inspect, They lost it......

We are seeing a lot of this noise problem, anyone got any answers?

Re: Vibration noise on MP C2551

All bar none of the machines I have seen with the noise do it when using plain paper - so i dont understand how adjusting down thick mode temps is going to offer a cure? The fusers seem to get very tight in the bushing/sleave area. I have shut one up with a few drps of silicone oil each end. Techs are often just fitting new fusers. Has anyone tried the "optional" fuser oil roller assembly as shown in the manuals fuser rebuild section (part number D0394380)?

Hmmm I just had 2 Ricoh TSM's on site and they witnessed 3 machines with the noise. We replaced 2 fusers with new fusers, and they took the 2 noisey fusers for the product specialist to examine. The next day I fitted 1 of the new fusers and 2 other noisey (not new) fusers with the optional oil roller. As for now the jury is still out on the oil roller. The TSM's didn't know about the optional oil roller, or why it is optional.

Ricoh knows about this, but they don't have a fix yet....

So the TSM's have clearly never looked at the fuser section of the manual, or looked at bulletin 22. Makes you wonder.

Any fuser rebuild I do gets greased up as a matter of course, they all tend to get noisey otherwise

same problem? help.

Re: Vibration noise on MP C2551

Still don't have an answer from Ricoh, however they did recreat the noise with 1 fuser I sent them......

Replace the cleaning oil supply roller inside the fusing unit. This is a common issue with the old MPC4500. It will moan and vibrate like a cat when the oil is dry out due to the heat.

I have the same issue and I still can't solve the problem after putting grease. I did the output check on so mode and check on the fusing exit 60mm and it emits the sound. But the fusing exit 120mm doesn't. Only at slower speed it makes vibration noise. Any other advice? Thanks

Bumping this thread back up.


I hoped to find out if anyone had found a sure fire resolve for this issue?

I've got one in the office we're hoping to ship out, and the vibrating noise only really occurs when turning the machine on. Or after a multipage print job, the noise will kick in once the machine has cooled down.

I get the noise for a max of 5 seconds and then it goes. I took out the paper exit unit and lubricated the plastic rollers and that seemed to clear the fault. Now i'm thinking its the fuser like so many of you have said.
I have lubricated with thermal grease the one roller, but the other's a prebuilt unit that I can't see any way to lubricate without damaging the machine.

Re: Vibration noise on MP C2551

The MPC2051 is the slower brother of this one and has given us endless trouble with this noise.

We (on our own accord) stripped the fusing sleeve section and discovered that it contains a lube "bar". This is actually a piece of plastic with cloth wrapped around it. When (whatever) lubricant is there when new, wears off, it slowly starts to migrate off the "bar" and make its way onto the metal frame that shapes the sleeve - this acts like a handbrake and causes the noise.

We strip the sleeve assembly and use a high temp lithium grease* to lubricate the "bar" plus the inside of the sleeve - tucking in the cloth so that it does not extend past the area it is meant to be. Then clean the orange ends of the opposing rubber roller as this prevents fusing jams because the ends are all that drive the sleeve.

Further make sure that the sleeve is clean, as greasiness will also aid jams.

Then make sure to re-assemble wiht the side marked "F" to the front side of the fuser and the noise is gone!

I keep a "fixed" fuser in our workshop and when a tech gets a call for a noisy 2051, i hand him the one I have and he returns the noisy one, which i then "fix" and keep for the next turn.

Hope this helps.
