It’s perfect! Do you guys already do this?
I open a letter, I take it’s picture with FairScan. The FairScan-folder on my android device gets syncthinged to the ingest folder for Paperless-ngx on my “server”. Paperless imports it, deletes the file and sets the new documents tag to inbox. I decide if the document goes to the binder for important stuff, or if I just toss it in a binder with all the paper I most likely will never touch again. Next time I look at Paperless, I edit all documents with the inbox tag and remove the tag.
I have yet to use a consumer ADF scanner on a printer that didn’t feed the paper at an angle until they are crushed and folded, doesn’t matter if the guides are perfectly set for A4 either. It has never worked for me.
