Xerox Docuprint M760 color problem

Archived from groups: comp.periphs.printers (More info?)

I've just acquired a Xerox Docuprint M760 which had not been used for about
18 months. After cleaning it, it works fine except that colors come out as
different shades of green (like gray shades, only green!). This is the case
with the test page and other color prints.

Has anyone come across such a problem or have any idea what might be
causing this?
