SOURCE: SMB Scanning to a Macintosh

SMB can be a bit tricky on Mac as the aliases etc, & paths can easily overwhelm the MFP. Try FTP as a better alternative. Use "Locations" on Mac to setup a static ip# they can switch to when scanning. I have found the KM machines a bit more fussy than Canon with regards to SMB as you can usually browse better on the Canon devices. I have seen the "Reference" browsing on KM allow you to see into the Mac yet will not allow scanning to the set location. Our KM reps always recommend using the ip# of the device vs Netbios name. To me that sort of defeats the point of using SMB anyway. Scan to PC over SMB seems ok to computer Netbios name as long as DNS is registered & working OK on the LAN & WINS is properly configured as well.

I had the same recently.

Problem is caused by a paper which stuck behind the paper tray. It happens when You put to much paper od while moving (for example). Solution: take out the paper tray 1 and 2, remove the paper from the space behind the trays.
