C658 c-3102 error, fuser drive assembly?

[FuserNoob]

Hi again everyone,
I have a customer with a C658 displaying a C-3102 error with an associated gear/slippage sound coming from what sounds like the fuser drive assembly. I ran a load check on code-45, multi code-8, Soaking Roller Pressure Solenoid and was able to duplicate the sound.

I remember reading something about an updated fuser drive assembly, but can't find the tech bulletin.

Can you check my math on this before I order a $350 part?

I need to replace the fuser drive assembly, part # A79JR71633, correct?

Thanks again!

Since the fuser unit is much easier to replace id start with that

[kingarthur]

They brought out a mod for the fusers, the cleaning roller would seize, you had to install proper bearings in place of the bushings. - however, any recent fuser should already had the mod

is there rust dust near the door hinge area by the fuser?

yes, that was the first thing we tried

you mean like this?

[Synthohol]

yup.
replace fuser drive assy.
and the fuser that gave it such a hard time turning.
or remove the cleaning roller to buy some time with it. <- saw you did already

That's the revised version, correct?
Thanks!

always wanted to try spraying white vinegar in the rusty clutch and follow with IPA after 60 min.
the vinegar eats rust like a demon and would likely give the clutch plates new life but i didnt want anyones office to smell like a Salad-Hut.

I just use plastic safe contact cleaning spray with the pipe attached. Water will condense inside it, make sure to get it dry as quick as possible. I do this as a preventative measure on clutches around the 400K mark.

Could not find a bulletin, but that is the updated number

The guy who did my initial training on copier repair swears by DeoxIT as a cure all:

Thanks for reminding me that I have some. I'm going to give it a shot. At this point it can't get worse

Pretty much all of our 8 series needed to have their fuser drives replaced at 1 million, we kept a couple rebuilt fuser drives in stock and swapped out as needed.
