Hi RGB,
I think we should download the latest driver on the Epson website - found here - https://epson.com/Support/Printers/All-In-Ones/... - 2 links below, 1 is just for the printer driver, the other has all the other goodies.
Printer Driver - https://ftp.epson.com/drivers/epson15480.exe
Driver and Utilities Combo - https://ftp.epson.com/drivers/epson15711.exe
Once downloaded, we are going to remove your Epson. Click start, and type "devices and printers" - find your epson, right click and delete/remove.
Once done, reboot.
Once booted back up, run the driver you downloaded to install. Let's see if installing the printer with the updated Win 10 64 driver returns the functionality you are looking for.
Let me know!
