Kyocera 3252 - Yellow Drum Not Spinning, No Yellow Print

please don't remind me of the Falcon series
Lauch was in 2005 and I got a lot of gray hair from it.
The Hornet 3/ FS-9530DN, on the other hand, was a workhorse.
5 million pages were no problem with good maintenance

This sort of issue is very old, ... all the way back to Falcon1, Falcon2, and Falcon3. Especially, immediately after changing a drum unit. The coupler seizes in one position, and cannot mate to the new drum unit. On the Falcon series, at a drum replacement I would put a couple drops of oil on the coupler and worked it in and out a few times to make sure it could move.

Congratulations on your success!!

That's exactly what it was. It's now fixed. It was stuck in the disengaged position. Thank you so much for all your comments. They're very helpful. Especially the picture.

Peter did you resolve your issue?

[KYO_OEM]

not needed, entrance from the front.
Couplers are no component from main drive unit.
After you removed all 4 drums, dv units and transfer belt, you`ll see all 4 drum couplings.
Use grease for all 4 coupler and after reassemble from all parts, system will work.

When inserting the drum and developing unit make sure are you are fully engaging the lock shaft on the developing unit. Otherwise you will not get color for that unit.

I forgot to ask you. Do i need to take out the whole drive motor? Is it possible to access pulling out the drum and developer and fixing frome there? If I need to take out the drive motor do you know either a good video or manual for that? Thanks in advance.

did you checked the springs for coupling?
We have had no magenta and no cyan after maintenance

Where is that? Is it in the printer or in the drum? I've checked the drive dog from the drum. It seems to be fine. It works in another printer as well. I may not understand what that part is "springs for coupling" in this case. I'm not a native English speaker.

This is still the most likely cause.

Agreed.

Right. The drive dog. He checked it already. Right?

Doing test, I pull out the cyan drum and the pull in without touching it. It makes the noise when it is properly installed. It aligns it perfect as the other. But no yellow and no cyan printing.
