scanning

I've registered to receive WIA notifications for all devices through RegisterEventCallbackInterface for WIA_EVENT_DEVICE_CONNECTED and WIA_EVENT_SCAN_IMAGE events. However I only receive notifications when scanner device is plugged in - I don't receive notification when I scan (for example with mspaint which uses WIA). Am I supposed to receive scanning notifications from applications or only when Scan button is pressed on a device? (I haven't tried the latter since I use a multifunction printer without Scan button). Is there any other way to be notified about successful scans through WIA? Thank you.
