Replacing the printer or changing the network connection

The installer saves the MAC address of the printer, so if you need to replace the already selected printer, or you are changing between Wi-Fi and wired network connection, you need to first uninstall and reinstall the Canon IJ Scan Utility. Even if you run the Scanner Selector application, it does not replace the scanner information in the scanner application. The Wi-Fi and wired network adapters have different MAC addresses.

  • Uninstall the Canon IJ Scan Utility
  • Reinstall the Canon IJ Scanner Utility (see above)
