Re: KM5050 random faint gray line

5050 paper path is simple as they come. With a clean machine and new OEM parts and supplies there cannot be this defect. Are you on site or one of your techs? Something doesn't add up.

Maybe the paper has defects from factory?

Laser? Unlikely.

I think I would very closely examine the area around the drum for fibers dangling onto the drum surface. I've found fibers stuck to the grid, statically attracted to the drum blade, or stuck to the upper developer seal ... really anywhere within reach of the drum. These fibers can be very very fine, and nearly impossible to see.
