I have a MF644CDW set up as a home printer/scanner. The printer is connected to the home WiFi network, and is mainly used by a Mac desktop at the other end of the house.
I was unable to get "Scan to Email" to work (will post about that issue separately) so have been scanning to Memory Media (a USB key using the front port) instead. Is there a way to access the files on the USB key remotely - that is, from the Mac?
I haven't been able to figure that out, so spend a lot of time walking the USB key back and forth - not ideal.
The printer does not host files for you to browse to from systems connected on your network.
The purpose of the port is to allow you to print files from or save files to the USB stick.
