Canon document scanner supporting duplex scanning. - Brand: Canon - Model: imageFORMULA DR-2510C - Type: Document Scanner - Features: Supports duplex scanning - Scanning Method: CCD sensor - Accessories: Power adapter, a set of spare replacement rollers No manuals included. Thank you for viewing. I used to use this, but I'm selling it because I switched to a new model. I was using it until recently, so I think it works, but I haven't reconfirmed its operation, so I'm selling it as junk. Please be aware that there are changes due to sun exposure. I'm also including a set of spare replacement rollers that I had left over.
