I just replaced my toner cartridge with an official Xerox black printer cartridge. At first, there was some ink dust on everything and then after a few pages looking bad, now each page prints black to white faded from the dark on the left to white on the right side. It's been pretty consistent. I have shaken the cartridge several times. Tried the "Clean" page selection in the maintenance menu. Nothing. I have only printed some 8000 copies out of this printer, so I doubt I need to replace parts. Help!
