Thanks for letting us know how you fixed the printing problem. I am sure it will help others that may have this issue in the future.
Hi to all,
I have a Workcentre 7225, it started printing green pages when you used the doc feeder or top glass, sending faxes and prints from all other means printed fine. If you have this problem update your firmware to 073 version, my copier had 072 before, this fixed it on mine.
