Mac PIXMA TR8620 scanner not found, cannot communicate error (solved)

All-

 

So I've been wrestling with this issue of the scanner not being found by the IJ Scan Utility Lite under Mac Catalina 10.15.7 where it wasn't finding the scanner and throwing the pop-up error:

 

  Cannot communicate with scanner.  Possible reasons:...

 

I could print fine but could not scan.  Printer was installed with Setup from the support page and added using Airprint Secure, but could not be found by IJ Scan Utility Lite.  However my Windows box finds the scanner portion of the printer fine.  I finally broke down and called support and I got it working.  Specifically, IPv6 needs to be turned off on the printer.  To do this:

 

  • On the printer, go the printer home screen
  • Click on the Device settings wheel
  • Click on Device Settings
  • Click on LAN Settings
  • Wi-Fi
  • Then click on the "Advanced" tab
  • TCP/IP settings
  • IPv6 - it'll throw a pop-up message, click Yes
  • Enable/disable IPv6
  • Click Disable
  • Exit back to Home

 

And you're good to go.  Hopefully this will save some frustration and time for others.
