when I print everything comes out perfect
when you copy in single color CMY come out perfect
when you copy in black only the image is distorted

Re: Xerox 252 Black copies

Is it safe to assume that when you print cmyk, and also print single k, that k is ok? And when you copy cmyk, the k is "distorted"? If the answer is yes to both questions, and you've changed the ccd, then I would replace the castors.


What do you mean distorted? "Electrical noise looking" or wavey lines, or what? Did this happen after some incident? Like maybe fooling around with whatever magic box (mcu maybe if their is one) receives the ccd info?
