MX4070 drum

[allan]

Has anyone been refilling and re-chipping these 203U iu's?
These machines are almost running at a loss with the consumables i am getting.
To expensive and does not make close to the yield its should do.
Some of the spent cartridges still have some toner left before the chip kicks in and the drums are still pristine.

Well, I rechipped Xerox stuff back in the day, so if you can find a decent chip supplier this will probably work.
I've been offline long enough that I don't remember where the mothership got the chips from though. Sorry about that.
