I have a Canon PIXMA MX700 connected by ethernet. When I first bought it I was using OS X 10.4, and scanner-initiated scanning worked fine. After upgrading to 10.6, neither scanner-initiated or scanning from MP Navigator EX works with the firewall enabled. The firewall lists exceptions for three applications:

  • Canon IJ Network Scan Utility.app
  • Canon IJ Network Scanner Selector.app
  • MP Navigator EX 1.0.app

I get no further blocked warnings, and /var/log/appfirewall.log lists nothing for today (my latest attempt to use it).

Try opening TCP port 5100 (scanner and camera sharing) and TCP port 49201 (I discovered that there is a lot of traffic on this port when scanning with firewall turned off). You can enable the passive FTP range in firewall settings (at least on the Snow Leopard Server)

Alas, I'm on a laptop, I can only select applications, not ports. – Justin Love Apr 12 '11 at 17:04

I don't have my OSX machine handy, but the issue isn't with the applications. If the scanning is initiated at the scanner, than the firewall is blocking the incoming stream (that is, from the scanner to the computer). I believe that instead you need to setup the firewall to allow incoming data over specific ports.

Is that possible in the GUI, or do I have to drop down to command line/config file? – Justin Love Dec 1 '09 at 21:06
@Adam, the Mac OS X built-in firewall is an application firewall, not a port-based firewall. – Arjan Apr 3 '10 at 11:18
