Hi Tbcarrick!

So that the Community can help you better, we will need to know the computer operating system you're using (Windows XP/Vista/7/8 or Mac 10.x). Any other error messages or details you'd like to give will also help the Community better understand your issue.

Hi tbcarrick,

If you have any antivirus or firewall software on your computer, please temporarily disable them and then try to scan again.  Sometimes these programs can block the scanning process of the printer. 

If you still are unable to scan, we can see if there are files in a folder called TWAIN_32 other than those related to the printer that may be causing a conflict with the scanning process and MP Navigator.  If there are, we can temporarily remove the files to see if this will allow you to scan.

To move the non-Canon Twain files from the Twain_32 folder, please follow these steps:

1.  Go to Computer / My Computer and locate the C: drive, then double-click on it to open.

2.  Locate the WINDOWS folder, then double-click to open it.

3.  Locate the TWAIN_32 folder, then double-click to open it.

4.  Inside of the TWAIN_32 folder, you will see a folder for your PIXMA MX320 printer as well as a WIATWAIN.DS file.  If there are other files in that folder, you will want to move them to another location, preferably your Desktop by doing the following:

    4-1.  Click on each of the other items in the folder other than the the WIATWAIN.DS file and MX320 folder to select them.  You will want to hold the the CTRL key on your keyboard while selecting each of the items until all of the items except for the two referenced above are selected.  Please be sure to leave the WIATWAIN.DS file and PIXMA MX320 folder inside of the TWAIN_32 folder.

    4-2.  With all of the items you want to move selected, please go to the EDIT menu and select the CUT option.

    4-3.  Go to your Desktop (main window that comes up when you start Windows with all of the icons on it) and right-click your mouse in any blank area, then choose the PASTE option.  The items you selected from the TWAIN_32 folder should appear on the Desktop.

5.  Try to launch and scan using MP Navigator again.
