Just installed Maverick and my Canon MP780 will print but no longer scan, would a new driver help? I get a message in the Image Capture window saying: No camera or scanner detected.

Scanner worked with Mountain Lion, but is not working with Mavericks.
On Canons website, this is the message on Canon's MP780 for Mavericks OS:
"There is no driver for the OS Version you selected. The driver may be included in your OS or you may not need a driver."

I know the hardware (Canon MP780) works as I tried VueScan, and the hardware scanned with this program - but I would have to pay $40.00 for VueScan.
Hoping there is a driver that would allow me to use my current software, without purchasing VueScan.
There are four options at present and being told you can't have the new thing without paying for an old thing to work means many people will resent the $40 option and be angry:


Pay the money and keep running Mavericks with VueScan to scan.
Don't pay the money and revert to Mountain Lion (or whatever previous OS works with your peripherals).
Get a new scanner.
Wait for someone else to provide a driver that either does more than VueScan or costs less than VueScan.
