I have 2 Phaser 6250 mprinters and they have been great.
Recently both have either started to print gray instead of black or have a Rego jam. Just before the jam there is a loader than normal whirring noise.
This is very rqandom but I would like to tweak the machines so we are back to normal.
Seems like commercial printer techs do not want to take a look as they say it is a Xerox and older than they now do.
I have extra Imagers, Fusers, Toners etc so have a lot of money invested in them and their accessories.
What suggestions can I get to help me.
