This is an older ScanSnap model. I was using it actively until recently, replacing consumable parts. I'm selling it because I got rid of my computer. There were no particular problems, but sometimes it makes a "kyu" sound when scanning. The part in photo 6 is worn, so I think it's probably here or around the roller in photo 5 (sorry if I'm wrong). Both are consumable parts. It's an old model, so it only connects via wired connection, which can be a hassle, but it worked perfectly fine as a scanner. Thank you.
