I have a PIXMA TS6320 that has been with me for many months on a Windows 10 machine that has worked fine in duplex mode. Doesn't anymore. It prints two of the first page and when it moves to printing the second page it looks for paper in the rear paper feed. I have reloaded software several times...setup looks okay...manual duplex (when selected)...paper source auto select...basically printer defaults. What went wrong?
