MP C5502 squealing sound VIDEO

[MP C5502 Fan]

Ricoh MP C5502 with about 40,000 copies. Copy speed and quality seem fine, but it makes this terrible squealing sound. Tech came and put some grease on the fuser assembly gears, but it hasn't helped.

Anyone have any ideas? Thanks in advance!

Hi there!
I bet it`s the antistatic-brush of the papertransferroller. There is a modified pn: D1446205.

Thanks for the suggestion. Any idea what causes this failure?

X2 on the PTR. Had a customer running special envelopes through the machine that bent the anti static teeth upward. They went through 3 ptr's before I figured it out.

Hi there!
Paperjam, cleaning bends the spikes (red arrows), bending them back is only temporary solution. Install the modified - OK.

WHY would you have a tech come out if you list yourself as a tech?

I say an end user...........you need to be honest here

I didn't list myself as a tech. I noticed that too, but I didn't do it.

Sounds to me like a motor or fan singing.

it sounds like a resonance, dont understand very well from the video, try to use the "output check" in sp mode to test the motorized parts one by one ... personally it sounds like the noise of the heavy metal bar inside the sleeve to keep / distribute the heat that has loosened screws well, but this is only a supposition

Re: MP C5502 squealing sound VIDEO

Whom ever the tech was didn't pursue the issue with any desire to actually solve the problem. Running various output checks would have been a good place to start to help isolate the problem.

Sounds too loud and not the right noise to me for it to be the PTR. In MY experience the PTR generates skewing and jamming often in conjunction with scratches on the paper and the noise is more of a hiss and not a vibration.

The noise in the video sounds more like a driven roller rubbing against something immobile. I have seen the rubber rollers slip on driven shafts to make contact with surrounding parts. I have also seen plastic guides warp such that they make contact with a moving part. If it is in the fuser there could be a build-up on the stripping plate or the belt assembly's pressure pad has gone dry (this means the belt assembly should be replaced).

Here is some updated video.

Note this is not just some random DIY thing - we are just trying to get some expert advice in order not to get screwed. We aren't in the US, so it ain't like home!

I noticed the noise is most prominent on 600x600, but when printing 1200x1200 (slower output), the noise is gone.

After seeing this video I'm with zed255. Definitely sounds like a stuck roller or bushing. It sounds like its in the paper exit. These aren't very hard to pull out.

Re: MP C5502 squealing sound VIDEO

Does it make this sound when you first get the copier going in the morning? Or does it make this sound the whole time it feeds paper? We have had the rollers on the underside of the PTR case become dislodged/wedged causing a sound similar to this, but the odd thing was that it only made the sound a couple times a day (usually during a duplex run), but ALWAYS made the sound upon first starting up.

Re: MP C5502 squealing sound VIDEO

The rollers I'm talking about reside on the rear side of the Paper Transfer Unit on the Right hand Door (Picture 1). And Picture 2 show where on the PTR the rollers are (to avoid any confusion).
