Brother ADS-4550W document scanner A4, 600 dpi, Wi-Fi, LAN, USB 3.0

A document scanner is built for sheets, not for books or photos like an ordinary flatbed. The ADS-4550W is made for digitising invoices, contracts, waybills and other A4 paperwork. Documents end up in your archive, accounting software or a shared folder, and nobody has to retype them by hand or dig through a binder on the shelf to find them again.

An optical resolution of 600 dpi leaves plenty of headroom for documents: an ordinary office letter often needs a lower setting, while the higher resolution pays off for fine print, stamps and signatures. Because the figure is optical rather than interpolated by software, the detail is genuinely in the scan. That also helps text recognition when scans are turned into searchable files.

Over USB 3.0 the scanner connects straight to a computer. The LAN port lets the ADS-4550W sit on the office network permanently, available to everyone without being tied to one person's PC. Wi-Fi (802.11n) means you can place it where a network cable will not reach, such as a lobby or a shelf in the corridor.

The scanner handles documents up to A4, which covers most office paperwork: contracts, invoices, letters and forms. At 2.7 kg it stands firmly on a desk, yet it is easy to carry to another room when needed. Larger drawings and posters are beyond this model.

Accounting teams and agencies that archive invoices and contracts digitally; small and mid-sized offices where one networked scanner serves several people; and organisations that want to shrink their paper archive and keep documents where they are easy to search and share.
