This solved my problem. My Canon MX870 was connected wirelessly. It was able to print, but not scan ever since a recent move. It showed an error message indicating that the printer was off or not connected to the network.
I did not originally have the "Canon IJ Network Utility" on my computer, but I reinstalled the printer driver from the Canon site and the utility appeared afterwards. After I followed the instructions I was able to scan!
