yup, bearings are croaking, sometimes you can oil them when its nice and hot so the oil flows into the bearings or just replace the fuser, its not long for this world.

Unfortunately sometimes is too late to replace bearings when shaft axes are worn.

You posted that you already replaced the fuser belt. Was it making noise before you replaced belt? If not it may of been something put back in wrong. When replacing the belt that fuser has to be almost completely disassembled and maybe something was put back in wrong?

At this point it may be worth just getting a new or used fuser and be done with it. Keep the fuser with noise for parts.

Shaft axis are ok. May be noice comes from new bearings. In Europe I found onlybearing.JPG

They look like correct bearings. It's possible one could be dry from factory? Even with that if you lube the bearings noise should go away, even if temporarily.

Ok, I'll test it. I'm not shure if the "waistband" making the noice.

FYI for anyone rebuilding these, you can order bearings straight from Konica on your normal parts order.

P/N is A00V240600 (Cheaper than most aftermarket suppliers too)


Or if your a Ricoh dealer use 0742-3808 (Twice the price though from Ricoh!)

Can the optocoupler be defective and keep opening and closing?

I made a fool of myself with the heater: C-5501 came from a bent pin (black cable with bridge) and the noise from an incorrectly installed socket on a large ball bearing...
