I have discovered that when I was using Linux Mint 17.3 this MFP Laserjet 477 fdn worked fine both for printing and scanning, but now that I have upgraded to Linux Mint 18.2 the printer works but there is no driver that I can find for the scanner. So scanning is a problem on 18.2, the message I get is SCANNER NOT FOUND, I think it needs a driver, but no drivers are available for 18.2.
I can not scan from the computer, so the only work around I have found is to scan to a flash drive, then plug into computer and take the scanning documents from there, a lot of work because there isn't a driver available for 18.2
