Hi, I removed the yellow drum from my Kyocera 3252 to check it, and after putting it back, it stopped spinning. The developer is working, and I can see toner building up only where they touch, but the printer is not printing any yellow at all. Any idea why this happens?

The drive dog at the rear is spring loaded and it has stuck in the disengaged position. You will need to free this up and likely replace the drum as it will have been damaged by the developer rotation. Make sure when you fit a new drum to rotate it until the drive engages. I’ve had this happen a few times so always take this precaution now. -
Also, the little circlip that holds the drive cog in place fails, then when you pull the drum out the cog moves too far forward and it's drive pin falls out meaning no drive is transmitted to the drum, had it a few times. It's not obvious when looking in from the front unless you know to look for it.Comment

Thanks for the suggestions. I checked the drive dog mechanism, and it seems fine. However, the drum is still not spinning. I even tried replacing it with another drum, and the same issue persists. It’s as if the machine isn’t sending the command to move the drum. Could this be a problem with the motor coupling, a sensor, or something related to the activation signal?"

There is only 1 motor for driven all 3 colors drums.
Each similar case in past would solved as Ropariva suggested. (in case that it happened like your describtion)
If not, new main drive unit needed.
Remove all 3 color drums, touch and turn the yellow drum coupling and compare with cyan and magenta.Comment

In that case, I’m not sure what’s happening. The magenta drum is still working fine. First, the yellow drum stopped working. Then, after testing with the cyan drum, the same issue happened. Now, only magenta and black are working. Any idea what could be causing this?Comment

At first i would try to use a little bit grease on the couplings from all 4 drums.
Now both couplings from ye + cy are not working probably.Comment

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.

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

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
