We have the same issue with our brand new 8560 MFP/D - The color prints were great and then the next day they are not as bright and the font almost looks like it has a lil blur to it. I went through the basic trouble shooting steps already
What specific model printer do you have? Xerox has a Phaser 7500 and there are WorkCentre 75xx printers, but not a WorkCentre 7500. Please let me know which specific model number you have and I'll try to help you figure out what happened.
