Canon PIXMA 860 and 560 not recognized by Image Capture

Question

I can scan from the printers to my MacBook. And I go to System Prefernces / Printers and Faxes and both are shown as printers and as scanners. I can open from their and scan but when I open image capture it doesn't find any scanners.
I down loaded and installed both the newest canon printer and scanner drivers as well as the newest ICA driver. Still they are not recognized.
What am I missing?

Just for testing purposes, I removed the canon printer, removed all canon software and updates from my system and then used the original CD that came with my 870 to reinstall the printer and lo and behold, Image Capture started working again for wireless scanning.
Hello and thanks for the feedback.
There are two scanner drivers available for many of the new models of Canon AIOs. There is the ICA driver and the Canon scanner driver.
During my tests on clean builds of 10.6.x I found that my Canon AIOs were able to print and scan via wireless by simply installing the Canon update provided by Apple. This update consisted of the then latest printer driver for many models of Canon AIO and inkjet and the ICA driver. Canon's scanner driver was not included as part of this download from Apple.
The ICA driver is installed in HD > Library > Image Capture > Devices and the package is called Canon IJScanner1. Later versions of the ICA driver also installed another package, Canon IJScanner2. These ICA drivers provide a minimal amount of scanning selections and only appear to work with Image Capture and Preview. Other applications like Canon's own MP Navigator and Adobe Acrobat Pro will not scan with just the ICA driver installed. The Canon scanner driver for the respective model is required.
From what you have said and from my own testing I propose that the original CD did not contain the ICA driver but the Canon scanner driver for the MX870. And with only this driver installed you were able to scan using Image Capture via the wireless. I don't recall ever testing a 10.6 build where only the Canon scanner driver was installed and not the ICA driver (it is present by default on 10.6 but only has older models of Canon AIO's - your MX870 is not there). Had I tested this I believe that I would have been able to scan via wireless using Image Capture.
I also propose that once you installed the Canon v2.4.1 update, which contains a version of the ICA driver package that is also available from Canon web sites, then Image Capture stopped using the Canon MX870 scanner driver and used the ICA driver instead, thus stopping you from wireless scanning.
Right now I am using a new build of 10.6.6 on my MBPro. So that I could print to my MP990 at home and an MG6150 at work I simply installed the v2.4.1 update and have printer and scanner queues in Print & Fax for both. I have not installed scanner drivers for either device and at home with my MP990 Image Capture does not show any device being available, while Preview does show the MP990 once I select 'Import from Scanner > Include Networked Devices'. Also, Acrobat Pro 9 does not show my MP990 being available.
And with regards to the v2.4.1 update, the drivers included are provided by Canon to Apple, just as the other vendor drivers are provided to Apple, to make life easier for us Mac users. The drivers are available individually and get downloaded and installed automatically when the respective model is connected to the Mac and no local driver is present. As for the package including all these individual vendor drivers, this would be created by Apple.
