I'm having issues scanning documents to the computer. Printing is fine. It was working fine until the other day, although I can't think of anything that has been changed that could have caused it to stop working.
I have checked that the IP matches (I have also tried changing the IP).
And that the folder that the files are going to have the correct permissions
The firewall is not blocking any connections that I can see.
I can't see any other solutions!
