I've used duplex printing with this printer for years, but I was getting red streaks along the side of pages, so I reinstalled the same driver--Universal Printing PCL6--and updated the firmware. Now I can't get the duplex to work. Devices and Printers>Device Settings says it's installed. I've checked Print on Both Sides in the printer properties for my document. I've uninstalled and reinstalled the driver a couple of times. There are no error messages. What's the fix for this? Thanks.
