The copies on this machine are washed out The prints from inside the machine are perfect (Status page ,config page ,etc). If I take that page that just came out of the printer and copy it it is washed out --- evenly washed out. no color is lighter or darker than any of the others----I took the top off the scanner assembly cleaned the under side off the top glass and the slit glass cleaned the lamp assembly mirrors and such and reassembled. NO CHANGE I'm replacing the scanner assembly complete, scanner pcb the whole thing. Anything I should go and adjust (calibrate) or take note of when replacing the whole unit???
