Recently purchased a used 740. So far it works beautifully and I would like to keep it that way. In the User Guide that came with the printer under the Help Pages tab there is a reference to a CD-Rom with respect to cleaning procedures. I do not have this CD. When I contacted Xerox to see if I could get one they were not helpful and seemed to have no clue about what I was asking for. Does anybody know where I can get one, or can somebody burn a copy and send it to me? Any help would be greatly appreciated.
