770 Install, Can't access Scan to printer (but printing works)

This Microsoft page appears to indicate that sometimes "all in one" devices appear as printers on the list of devices.  (Both of these printers are "All in one" devices.)

I am a bit "old school" and use the Lan Setup feature to assign specific IP addresses to important devices on the network so that once my computers have established connections, the devices remain at the same IP address.  (well, actually 90% of the devices on the network.)
