KIP 3100, Meter 74K. On the far right and far left the image has small, short (1/4" to 1/2"), thin lines and background (speckling). It's all random, comes and goes in no particular pattern.

The lines and speckling appears in a 6" column on the far right and the far left. I can see it on the drum when I open the unit, clean it off and it comes right back. Developer roller looks normal, toner level in the Developer looks normal.

I have units with more usage and the drum-cleaning roller has never been replaced and there is not an issue. (?)

Not sure, but have you checked the IM, and T/S corona wires, perhaps even just replaced them?
What about the assemblies themselves?
Had a 3000+ recently give me grief, the LED's were putting out all kinds of random images, it turned out to be an issue with the IM corona grid screen

Best wishes

By IM Corona I assume you mean the Charge Corona, yes, the Charge Corona has been cleaned. The image also had some hazy vertical lines, they disappeared when the Charge Corona was cleaned.

I cleaned all the Developer contacts, drum contacts, drum cleaning roller, but no change. Swapped the Developer and image is good. Then I put their Developer back in and the problem was gone. (?)

Yep, this one is going to haunt me in my sleep.

Make sure that the wiper blade on the blade roller in the developer mod. is cleaning the roller like it should be. Did you clean the optics? also check the fuser roller for excess toner.
