When trying to duplex print a document, the first page is always printed without page 2 on the obverse. There after pages 2&3, 4&5, etc. are printed out without a problem. Any ideas for a fix? This happens with Word and PDF documents on my Mac.
I am using the latest Mac OS 10.14.6. The problem has existed since in first installed the printer. I have installed and reinstall drivers to no avail.
