This item is brand new and unused. The outer box has been opened for photography, but the inner packaging is as it was when purchased. I purchased it about six months ago from an electronics retailer for around 30,000 yen, but I haven't had the opportunity to use it, so I'm putting it up for sale. It scans A4 color double-sided documents at a high speed of approximately 40 sheets/80 sides per minute*1. You can set up to 80 A4 documents*2 at once, allowing for smooth scanning of large volumes of documents.
