Click on any other icon in the 'Printers and Faxes' category (assuming that there is at least one icon remaining).

If the icons for your MX330 printer and MX330 fax are still there, right-click on each of them and select 'Remove device'

Go to Control Panel > Programs and Features, find and select 'Canon MX330 Series MP Drivers' and click 'Uninstall'.

Disconnect the printer from the computer.

For the 32-bit version of Windows 7, you should download ' md86-win-mx330-1_02-ej.exe' - click the 'Download' button and save the file in a location that you will remember (e.g., your Desktop).

Make sure that the website has correctly identified your version of Windows and then click the 'Select' button.

and click the 'Drivers and Downloads' button Given that this is essentially the process that seems to have caused your issue in the first place, I don't have a lot of hope that this will fix things, but this is what Canon recommends as a first step. If troubleshooting a communication issue, reconnect the data cable (not applicable to WiFi, Bluetooth or Infrared).

Unplug the printer's power cord for approximately 10 minutes, and then plug it back in.

Disconnect the data cable from the printer (not applicable to WiFi, Bluetooth or Infrared).

Turn the printer off with the Power button (if available).

I don't have a definitive answer for you and the following are only guesses.

Now select (click on) 'Device Disconnect' and you should see 'Windows Hardware Remove.wav' click the 'Play' button to listen.

After you select 'Device Connect' you should see 'Windows Hardware Insert.wav' under Sounds click the 'Play' button to listen to the sound effect.

In the 'Program Events' window, scroll down until you see 'Device Connect' and click on that to select it.

Go to Control Panel and set the view (upper right corner) to 'Small icons'.

If you aren't sure of what you're listening for, you can hear the sound effects as follows: You should hear the two-tone 'Device connect' sound. With the printer connected to your computer, turn off the printer. In my reply to your question about 'offline' status, I asked if you hear the sound effects when you connect the printer. I suspect that's why the troubleshooter wants you to set the Fax functionality of the device as the default printer.

It seems that for some reason, Windows is having a problem communicating with your printer.

I've never found the Windows 'troubleshooters' to be particularly helpful.
