Brother DS-940DW Reviews

The perfect balance between performance, quality and portability at an affordable price

Design and Features

Let's talk about the design of the scanner. The entire scanner measures 1.8 x 12.6 x 2.5 inches and weighs about 1.5 pounds. It has wireless support and an internal power supply that allows the DS-940DW to work without wires or cables. This feature is critical, especially when you are on the go.

It supports swipe cards, allowing you to scan autonomously without linking to a laptop, desktop or smartphone. When you get home or to the office, simply transfer the scan results to your PC and you're done.


With the DS-940DW, you get Brother's iPrint&Scan (for Windows, macOS, iOS, and Android) for connecting to the scanner; BR - for scanning and storing receipts for financial data; Kofax Power PDF standard for creating and editing PDFs; Nuance PaperPort SE 14 for document management; and Nuance PaperPort SE 14; and Presto!BizCard for scanning and archiving business cards.

These applications should provide everything you need to scan, save, convert and manage your scans. In fact, many of them have overlapping functionality. You may find yourself trying to decide which program best meets your needs - it's a matter of quality.

Scan to local or shared destinations

Wirelessly scan to mobile devices, PCs, and if you use Brother's free iPrint&Scan,4 you can scan documents to network destinations and cloud services.

Optimize images and text with ease

The bundled software suite includes document management and OCR software, so you can optimize scans and convert hardcopy documents into editable Microsoft Word files.

Scans a wide range of materials

Scan documents up to 72 inches long and weighing up to 72 pounds of securities paper. You can also scan business cards and plastic ID cards in the same location.

Simple, fast and stand-alone scanning

There are many single-page portable scanners available, and in most cases they are so similar that I went into this review with buzzed expectations. But the DS-940DW essentially raises the bar in several key areas, including speed and accuracy. The package is complete, though not unique, and the ability to scan to a microSD card makes carrying the scanner around and scanning on the go less cumbersome and complicated. Add it all up, and the Brother DSmobile DS-940DW's advanced manual-feed portable scanner technology is enough to win Editor's Choice.

Main Features

One-way duplex scanning: To save time and help avoid document spoilage, the DS-940DW scans both sides of a document at once, eliminating the need to rescan the document.
