Plustek MobileOffice S400

No. Plustek's own S400 documentation describes a USB bus-powered, manual-feed CIS scanner that scans one side at a time, so it is not a battery-powered duplex ADF model. [The official S400 datasheet identifies it as simplex and USB-powered](https://plustek.s3.amazonaws.com/downloads/english/leaflet/plustek_catalog_03006_v1.1.pdf).

It has a 600 dpi optical resolution and is rated at about 20 seconds for an A4 grayscale scan at 300 dpi. That is suitable for occasional document capture, but it is much slower than a modern office scanner with an automatic feeder. [Plustek lists the resolution and scan speed](https://plustek.s3.amazonaws.com/downloads/english/leaflet/plustek_catalog_03006_v1.1.pdf).

Yes. Its published maximum scanning area is 216 by 910 mm, or about 8.5 by 36 inches, which covers long receipts, forms, and banners narrower than A4. Paper must be fed manually because the S400 has no ADF. [The official datasheet gives the long-paper limit](https://plustek.s3.amazonaws.com/downloads/english/leaflet/plustek_catalog_03006_v1.1.pdf).

The S400 included Plustek DocAction, NewSoft Presto! PageManager, and ABBYY FineReader 9.0 Sprint, with TWAIN support for compatible imaging programs. Its published operating-system list is from the Windows 2000, XP, Vista, and Windows 7 era, so modern compatibility should be checked before purchase.
