Is there a way to share a scanner with an Airport Extreme?

"From what I can tell the Canon MF4350D is not a network-ready device. In your case the Airport Extreme is just acting as a print server. As far as I can tell the Airport can't act as a ""scanner server"" (nor does such a thing exist, afaik) so your best bet is to just plug the unit directly into the PC that needs to do the scanning. For what it's worth, the sibling unit of your printer, the MF4370DN, is a network-ready printer and appears to be able to scan across the network when using Canon's software.

EDIT: Apple has a document on the limitations of the Airport and printer troubleshooting. Other searches have pretty much turned up the same thing; you can use it as a print server but other features of the printer are right out."
