Bizhub C368 fuser noise

Re: Bizhub C368 fuser noise

I would recommend doing a low check on the fusing motor with the door open. I've seen at times noise is actually coming from Gears on the opposit side of the fuse or on the door . Specifically the paper exit white gear sometimes is loose

Also since you Already checked the fusing unit you may want to examine the RU in the rear corner. Which also is known to make screeching noises.

Re: Bizhub C368 fuser noise

It was on the right side mainly, on the gears, if you turn the fusing unit on its right side some should fall from out of the unit itself, and in the back corners of where the fusing unit sits, but be careful because it DOES NOT like to come out of clothes

If I don't get it wrong, are you talking about these? Thank you

I tried to put fuser grease without success. Some have reported noise problems to me in the past but sometimes it resolves itself. For the moment it has suddenly appeared. My suspicion is that it comes from some clutch/gear from the Fusing Drive Section. But to get into that area, it's very complicated

Do you mean the paper exit unit? I had a case on a bizhub 458e but it doesn't seem the same noise to me. Furthermore, the noise seems to be present even when the rollers of the paper exit unit do not turn but the printer is warming up. Thank you!

Take out the 4 black passiv rollers after the fuser and put grease on the center. Also the passiv rollers on the door. These plastic rollers can squeek like "metall friction" I had many of these..

Will possibly become time for inevitable if you can't find it in the paper path or on the door to dig in from the back covers.

I had to change two or three times CL6 for noise in 4series

Re: Bizhub C368 fuser noise

I have a lot of these in the field. I have dealt with fuser noise on several of them. Majority of the time it is fuser related. A handful of times it has been fuser drive related. In that case I just replace the drive unit as a whole. It may seem lazy but if I'm going that far in , I'm not taking chances. It was a nightmare at first but now I have it down to about 1-1.5 hour job total. Not too bad.

This may be a coincidence but I have had very good luck diagnosing this using the following procedure.

Run 45-1 load check to run fuser....run 45-1 in both pressure and retracted states (45-6 and 45-7) When the fuser is the culprit the noise will appear in both conditions.

When the culprit is the "fuser drive" the 45-1 noise only happens in one of the 2 conditions (45-6 or 45-7, I honestly cant remember which one) but point is if its noisy in both its fuser, when it goes away from changing conditions its drive.

I have only had like 3 drive units be the issue so that could be a coincidence.... but all 3 had that exact symptom in load check. If anyone else runs into it let me know if I am correct.

Very useful information, Thanks MVP.
