BH-C-284e, my first rusty CL8

[Hansoon]

Wow, I hoped since the dreaded BH-C-353 rusty clutch issue I never had to work in that part of the newer generations color machines another time, but KonicaMinolta is doing it again. Saving half a buck on the quality of their clutches. Now I have my first rusty CL8 in a BH-C-284e.

Seem to remember there was a shortcut too to take that piece of crap out. Can I just take the shaft alone out to remove that clutch instead of the whole drive unit?
Anyone willing to PM me that, please?

Thanks in advance

Yes you can remove the shaft with the drive unit while its in the machine.

There is a plastic wiring guide and a fan shroud plus housing in the way from the back to get to the shaft end from the rear. There is a C-clip and a bushing leave those, I think the whole shaft pulls out to this side. Then the connector. Inside its a C-clips a gear and a bushing.

If you don't use a magnetic screwdriver you will drop the C-clip. If you use a magnetic screwdriver the C-clip will shoot away. If you get past that you will forget were you put the C-clip...
25min plus 5min swearing at a C-clip. Job done.

Attached are both replacement versions, the correct way and the shortened version

Curious - no one mentions the number 1 cause of failure of this clutch.

Check the grey fusing exit roller shaft turns freely in the right side door - they frequently seize up making this clutches life very hard - it already has to drive way too much, it doesn't need another excuse to slip and shorten its life.

If it feels "ok" test it after largish print job. It's not uncommon to be "ok" at idle and seize up in use too.

I lubricate the bushings at every visit, unless a near new machine.

I have the exact same issue with my Konica Minolta C454e. The paper I jammed in the fusing unit just before exit. It kind of folds itself together. See picture.
Where is the CL8 located on the machine so I could check if that’s the cause of the issue?
I have looked for the grey fusing exit roller shaft but was not able to locate it. Is the any guide on what the different parts are called in the machine?
I want to take good care of my machine as it is an old one with 720.000 pages on the counter. Is there any guide for how to lubricate all the stuff in the printer and what kind of lubrication do I use?

fuser is issue not clutch if pages go under the pick off fingers.

[tsbservice]

The gray rollers are on the top of the DOOR.
Plus 1 to check your fuser. What is fuser counter?
Also using compatible toners may affect fusing.

Here's the easiest way to know. If you see a pile of rust dust right here, you need CL8:
