It sounds like a polygon mirror motor to me. Are there any other corroborating symptoms? =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Sounds like a brass motor gear turned into a router shaving a nylon gear.
Go into I/O mode and turn each motor on one at a time.Why do they call it common sense?
If it were common, wouldn't everyone have it?Comment

Check out the transfer belt cleaning unit. A piece of paper may be in the cleaning unit binding the driving gears. the gear making that noise is inside the copier on the end where you start your video. it chewed a couple of teeth off. Had this problem and there is a part upgrade for it.Comment

yeap thanks folks ..M38 spindle and gear 55 had a little misunderstanding
thanks again.
I got this vid from my manager, he did not have time to fix it( yeah right) ..changed the motor and the gear unit ,

Cleaned laser gaps, stabilized, Gradation adjust,.....it appear like if the image is being postponed by couple of miliseconds but with a less power, happening on Bk. .suspecting Bk drum...any suggestions.

Ghosting can be caused by a lot of things. Most common fuser unit.Why do they call it common sense?
If it were common, wouldn't everyone have it?Comment

That will be possibly my next step together with reconecting the HV unit, just want to get some more infos whilst waiting for brand new TR. It could be fairly misty inside the LU.Comment

Re: Have you had this sort of noise from machine?
OK.
My ghosting problem came back again.
Cleaned spotlessly everything on 2nd transfer side and it went away for 2 weeks. Now it came back again. Cleaned everything again as before and I was not so lucky this time. Problem still persists. It does not appear however on A4 R (A4 landscape) have not tried A3 yet...

Re: Have you had this sort of noise from machine?
those shadow around the print normally is paper dust on the ph laser window, the noise only the ph polygon mirror motor is spins that fast in the machine, so I can say your ph has a page paper or something loose in it.Comment
