Epson ES-C320W scanner, sheet-fed, duplex, 600 dpi, A4, Wi-Fi

The ES-C320W joins a wireless local network (Wi-Fi) or connects directly to a device via Wi-Fi Direct, with no router. It can sit on a reception desk, a shelf or in a corridor where everyone can reach it. A Hi-Speed USB cable connection remains available when the scanner needs to work with one specific computer.

In a sheet-fed scanner the pages travel through the device, so there is no need to place each one on the glass. Duplex scanning captures the front and back in a single pass. Invoices, contracts and forms are digitised quickly, with the page order kept correct. A sheet-fed scanner cannot scan books or bound documents.

An optical resolution of 600 × 600 dpi leaves plenty in reserve for documents: small print, stamps and signatures stay legible in the file. The maximum paper size is A4, which covers standard office documents, letters and forms. For digitising a paper archive, this quality is entirely sufficient.

Wi-Fi Direct creates a direct link between the scanner and a device, so no local network or network password is needed. That is handy when the scanner is used in a room without office Wi-Fi, or when a guest needs to scan a document without joining the network. The manufacturer does not specify which apps are used for scanning.

Small offices where several people share one scanner over Wi-Fi; reception and customer service desks digitising documents on the spot; accountants scanning invoices and receipts; and home offices where the scanner should not have to sit beside the computer. All of them benefit from a scanner whose location does not depend on where the computer is.
