C20 Print Quality Issue

Thanks for that

Have you had any of the IU's apart ...I suspect the dev. roller is maggled up. as machine was not used much, and I think humidity is the factor that kills it. Plus customers soft touch and voila 10k on the clock and already new fuser and now even IUs Bk and C to follow.

it is humidity and low volume environments, thats what i've experienced.

and the mottled effect is on the dev roller like its wet, if the new iu is destroyed straight away and starts doing the same thing then the toner will need to be changed too as its probably whats stuffing it up.

Guess what it came back. Bk IU Ordered will see, what it brings and I am not risking it and changing Bk Toner at the same time
