Hi Phil,
Thanks for writing to the community. I understand that you are having issues using your Epson Scanner with your ARM device.
In this case, what is your Epson Scanner model and the Surface Arm Device model?
Epson has actually released drivers compatible for your Surface Arm Device.
Epson and Windows ARM64 Support

https://download.epson-europe.com/pub/download/6700/epson670029eu.exe - Click this link to download the Universal Print Driver v2.90.00
If in case that a Windows 11 ARM compatible driver is not available, then your scanner will only work with basic features. Let me know if this would work.
If you need more help, please feel free to reply to this thread.
Best regards,
