MP W2400 fine black dots/dirty background

I beleive drum good for 20,000 meters or the equivulant of 65,000 linear feet. But I've had customers wear the drum did decay due to the length of time. Anyone see the same thing?

I've sold a number of these and other Ricoh Wide Formats and they all run a little dirty the second half of the PM and Drum cycle.

Thanks for answering!

I have read posts saying that drums from IPC should be better than Ricohs.

We'll try one of those.
Anyone who has experience with IPC?

You can extend Ricoh drum life by adjusting the Dev Bias Adjustment for the Image area SP 2201-1. I suggest taking it down to 525, check print quality. Around 425 w/ poor print quality is when it's maxxed out and a new one is needed.

We replaced the drum and it appears to have solved the problem.

Thanks!
