Hi,

just to check:
Get into Maint.-Mode. Print those Test Charts from Sim089. (Sample Set).
Is it on all Colours?

Btw: Newest Firmware on 250ci is 15. Might be good to know.

When you replaced the drum, was the charge roller also replaced?

I know on the 205c, 2550ci models the charge roller assembly can cause a similar looking problem that will create voids that look just like your example and can also cause marks in the same shape as your voids on prints that are low coverage. Haven't seen the problem yet on any 250ci series but I suppose if there is enough buildup of toner inside the charge roller gears or something causing it not to turn smoothly it could cause your problem.

Hi,

Upgrade Firmware is always good on this Type of Machine
Or just run Sim U119. Maybe Check wires behind the central unit.

Good luck
