We have a MX-M3070 with about 120K copies on it we recently replaced the Drum and later the Developer. Tech noticed Mag roller was very discolored with a dark Grey coating, Many years ago we had a similar issue with the Panasonic DP-2500 a mono component machine. We found that if we cleaned the roller with solvent it would resolve the density issue. This is the first time we have seen a Dual component developer machine. We are planning on replacing the unit but was wondering if any of you have seen this issue.
Thanks
