Hi llk,

If you print the network settings of the printer by following the steps below, is the link status that displays on the printout active or inactive?

Make sure that the machine is turned on.
Press the Menu button repeatedly until Device settings appears.
Use the button to select LAN Settings, then press the OK button.
Similarly, use the button to select Print LAN details then press the OK button.

We look forward to hearing from you!

I have a problem scanning on my mx340 after upgrading to IE 11. I'm using Windows 7 64-bit. I cannot launch the MP Navigator from the Canon Menu

What does the printout show that is of any use to solve this problem?

It has stopped working with LAN USB alos, so don't fret. Code 5, 145, 55 - but no way to find out what those codes mean, to troubleshoot. It's just a falming piece of garbage with no support. It won't even re-install drivers and detect the device - meanwhile the printer still works and the scanner worked yesterday.
So angry with Canon and the lack of support and their consistently garbagey printer/scanners.

Hi BonoVox.

The Canon Community Forum is not for immediate assistance. If this is a time-sensitive matter, you may click HERE to search our knowledge base, or create/log into a Canon Account and register your printer HERE for your personalized support options.

If the MX340 is not scanning by USB, WiFi, or Ethernet, and it is otherwise printing, check the printer's network settings page. For scanning, we recommend at least 80% signal strength. If the computer is a laptop, then for USB connectivity, ensure the computer is connected to external power. The USB signal while on battery power may be too low for the MX340 to detect.

If the above checks out, then ensure your firewall/antivirus is up to date, and add exceptions for the MX340's communications. For directions on adding exceptions, refer to the security software's documentation and support. A list of ports commonly used by Canon printers may be found at the following page: https://support.usa.canon.com/kb/index?page=content&id=ART174139
