I finally got an answer back from Canon – very interesting – here is what they had to say. So not 100% unequivocal – it’s possible but unlikely that your scanner might have a WIA driver.
From my POV, the interesting new information is that WIA is used to monitor for button presses.
Thank you for your recent enquiry regarding your Canon product.
Please be advised Canon stand-alone scanners use a TWAIN driver. In some cases a regional Canon company may also make a WIA driver available. However, this is not the case often since WIA has limitations which apply to scanning resolutions and not being able to scan film / negative.
The WIA service is used together with other services to monitor button presses from a scanner in Windows XP. This is the replacement for the still image monitor found in Windows 2000.
If you occasional see the scanner as a WIA device in an application then this is most likely an issue with the application being used. We advise you always use the TWAIN listing.
