C558 noise

[copier addict]

Hey all

I have a customer with a C558 that is producing a noise. I have been there twice without hearing it, but she recorded after I left this morning and sent it to me.
I am unable to attach it to this post, possibly because it is too large. The noise seems to be coming from the exit area, but in the recording it i difficult ti tell. The noise is a medium pitched steady whine. The volume fluctuates slightly. She tells me it happens in the AM more often. I removed the fuser and turned it by hand and no noise there.
I realise there isn't much to go on here, but does this sound familiar to anyone?
Any input is appreciated
Thanks

You're right. That's not much to go on.

If you trim down the recording to less than 1M then zip the file you should be able to attach it. Based on the intermittency ... what are the current toner levels? =^..^=

I have seen the transfer roller making a sqeeking noise. The front side gets dry. Throw a little oil in there and it is gone.

Exit rollers prone to squeaking, I usually just spray WD40 in that area then do a run to clear up excess. Bulletin will tell you to strip & clean or replace exit bushings etc but this is overkill.

Its this holder part...

The shaft chews thru the plastic holder until the belt starts to jump.
Does not jam but does make a noise.

I take the old part and drill and fix a brass bushing in there.

I agree. if its squeaking noise then probably the cause is transfer roller. One can also check by removing the transfer roller and also by manually rotating the tr roller. Lubricating the seating works! yes! damn right!

I hope this works.

Not the problem i am describing. Tend to agree that it could be on the fuser.
I have completely removed the cleaning rollers before just to get time to replace the fusers.
There is 3de party rebuild kits that include those roller bushings.
