Scanners can be a nightmare to work with. I’ve had this Canon MP495 Wireless Printer/Scanner for at least 3 years now. The wireless printing works on all my Mac computers, but I can’t get the device to scan via the wireless network. I even downloaded the latest Canon drivers as well as the latest MP Navigator software, but to no avail.
The solution seems rudimentary considering all the recent improvements in software and on network devices. The only solution that I have gotten to work is to connect the scanner directly to my Mac Mini via a USB port. In addition, the Canon MP Navigation software doesn’t seem to be scanning. I ended up using the Scanner software that comes with the Mac OS.
