I have 2 Xerox Workcentre 7335 printers that will randomly print unwanted duplicate copies. Sometimes the print job will square the number of requested copies, such as printing 3 copies of document x produces 9 copies, or print 4 produces 16. Other times printing a single copy of a 1 page document will empty the entire tray. This issue is very random, for most users it happens once per day or so. The issue isn't limited to a particular application, OS, or user. The error logs in the printer show nothing which corresponds with the times when this issue occurs.
I am highly suspicious that this is related to a driver problem. I have tried using the latest global print driver with PS, PCL5, PCL6 and am currently focusing on Win7 machines but results are inconclusive. Using a network installation of the driver vs installing the driver locally does not seem to have any effect.
Anyone have any suggestions on what to try with these printers?
Currently I am working with Version 220.127.116.11. I am going to expiriment further with PCL5 and 6 and PS to see if it makes a difference. The problem is very random and difficult to reproduce. It could take days to have enough events occur to make any determinations.
