The Fujitsu fi-8150 (PA03810-B101) is a document scanner with both an automatic document feeder and manual feed, so it can handle batches as well as individually fed documents.
Its feeder holds 100 sheets, and duplex scanning captures both sides of a page. The optical resolution is 600 × 600 DPI. For A4 black-and-white scanning, the listed speed is 50 pages per minute.
The scanner measures 170 × 163 × 300 mm (width × depth × height) and weighs 4 kg, giving a clear sense of its desktop footprint and weight.
