I am trying to scan photos on my Epson XP-820. I like the easy options from the Office Mode. However, I am unable to scan adjusting to the size of the photo. It is scanning at 8 1/2 x 11, and I don't see any way to scan to size. I didn't see this option in the Home Mode either. Is there anyway to scan my photos where the scanner will detect the object and scan to that size? The photos are all different sizes and I want the scanner to scan each one by detecting the size.
