On other Pixma devices, the button-controlled scan is used to be able to start scanning when in front of the device. You select in Xsane for instance, button-controlled scan, then click the scan button on Xsane. At that point, scanning is on hold, and does not start. You must go in front of the device, select the scanner mode, and hit the copy button to enable scanning by Xsane. This way, you can more easily scan documents that require some manipulations on document or scanner cover (e.g. for books)

And obviously, if I can't detect the scanner then I can't scan. Maybe there's some new trick added by Canon in the scanner network protocol, this would need to be checked. Do you have the possibility to take a Windows Wireshark log, and send it back to me ? Nicolas
