Plustek OpticSlim 1180 A3 Flatbed Document Scanner

This is Plustek's large-format A3 flatbed scanner, built for digitizing oversized documents, two-page book spreads, blueprints, and delicate artwork that can't go through an automatic feeder. It uses a CIS sensor with an LED light source for instant warm-up, capturing an A3 page in just 8 seconds at 300 dpi. The trade-off is that it's a flatbed-only design with no ADF, and it connects via USB 2.0 only. But if you need to scan bound materials or large-format media without risking damage, this is a reliable, purpose-built solution.
