If the AIO device follows the standards, Windows should be able to communicate with the scanner part of the printer through WIA (Windows Image Acquisition). I use always the Irfanview application to detect the scanner section from our (HP AIO) device. It pops up, I select it and then use the (Batch) scanning functionality from Irfanview to make the scans.
Till now that worked well enough for the (very) occasional use I have regarding scanning. Your mileage may...nay will vary. Especially if you need special features that are built-into the scanner section of your device.
