Image Capture does not recognize my Canon Pixma MP150 printer

To scan with Image Capture you need an ICA driver. Looking through the CanonDevices list in the /Library/Image Capture folder I cannot see an entry for the MP150. And I checked Canon Australia's web site and there is no ICA driver for the MP150. There is a scanner driver and MP Navigator for OS X 10.7. You may be able to install and use the driver and application on 10.9, although you will have to get past Gatekeeper to install both items as they are not digitally signed. To do this, you can hold down the Control key and click on the installer. A pop-up menu will appear and you can select Open. You will then be able to install the driver and then the application. If they do install then see if you can open MP Navigator and scan from the MP150.
