BH-C-280, weird pattern

However, the K-Developing unit is not driven constantly, it has its own clutch. Therefore we can almost sure take out of the consideration that the K-Units are being the cause when strange patterns in CYM appear. To complete the picture: The CMY developing units are rotating with the previously mentioned color PC motor M2. Torque to the CYM developing units is coming from M2 and being distributed to the CYM developing units by the Color Dev.Unit Engaged motor M10. So they all are only activated depending on the demand.

I don't think we can eliminate the K dev yet (although this doesnt seem like a dev issue imo):
Unless my beer goggles are extra foggy tonight, it looks like the "Developing clutch/K (CL6)" runs for about half the image process. Don't know if this model had the special firmware to not rotate the color IU's on K only prints as well so there another possible complication.

Do these marks have any color at all? Looks like K only to me. Also, upping the voltage might be able to clean it up?

Gaffers01 was right.

There was a lump of toner sticking to the K-developer roller.

Thanks to Gaffer01 and all of you guys.

Really
Next time maybe?
Although I must admit you also was right on money about second transfer.
Keep up this line 👌

Yes you too Synaux. Somehow on the small 12" screen of the computer I use in the car I overlooked your post more or less.

Sorry Pal!!
