Hi,
I recently bought an Epson Ecotank ET-4850. Pretty happy actually with the printer itself, scanning quality is also quite good.
However - it has a fatal flaw that i was not aware of.
I had an Epson WF-3620 that was able to scan to a folder, where Paperless-NGX then could do it's magic.
The ET-4850 doesn't support scanning to a folder. It does support WSD, but that's not really convenient...
Is there a way to do all this with a Raspberry Pi or another device that's connected to the MFD?
Maybe you could use Epson connect, have it automatically scan to a registered email, then use a script to check that email and dump the files in a folder.
