Can it scan both sides at once?

Yes. It has single-pass duplex scanning, so both sides of a sheet are captured in one pass at up to 16 ppm in color.

Does it work without a computer?

It can scan over Wi-Fi to a phone or tablet using the Brother iPrint&Scan app, and to cloud services. A PC is only needed for USB or desktop workflows.

What paper sizes does it take?

It accepts sheets from small receipts up to legal size, 8.5 by 14 inches. It cannot scan bound pages, books or thick cards.

Is it good for photos?

Not really. It is a sheetfed document scanner capped at 600 dpi, so it suits text and receipts better than photo-quality work.

Does it have a battery?

No. It is USB-powered, so it needs a USB port or power source while scanning, though the Wi-Fi link frees it from a cable to the computer.

How does it compare with a flatbed portable?

It is faster and smaller for loose sheets and does duplex, but a flatbed handles books, photos and fragile paper that this cannot.

About the Brother DS-940DW Compact Wireless Duplex Mobile Document Scanner

The Brother DS-940DW duplex and wireless compact mobile document scanner is ideally suited for on-the-go, small office/home office professionals featuring its compact, mobile design and simple workflow applications. The DS-940DW features single-pass duplex scanning and a color scan speed of up to 16ppm(1) (a single page in as little as 4 seconds)(1). This scanner can wirelessly scan to PC’s, mobile devices, and with the Brother free iPrint&Scan app, scan to cloud services and network destinations(2). The DS-940DW is compatible with the way you work. Its compact size and mobility combined with fast scan speeds and image optimization features, make it a perfect fit for usage on the road, in the home or small office. Open the DSD (Desk Saving Design) scan lid on the Brother DS-940DW document scanner to reduce the space needed to operate the scanner. The Brother DSD saves up to 11 inches of desk space(3). The DS-940DW uses the Brother “iPrint&Scan for desktop” app. Not only does this app make setting scan settings and adjusting the output super easy but, it also eliminates the “lost document.” Every scan initiated in the app goes directly to the app. The user then has the option of where to save the document, whether that be directly to their PC, to a network location or to the cloud. If a user often saves a certain type of document to the same location using the same scan settings, they can save it as a workflow and with one click the hardcopy document will be scanned and saved to the location and in the format the user wants. For added simplicity, the DS-940DW can scan directly to an installed micro SD card(4). With the DS-940DW also featuring scan to mass storage capabilities, a user can scan without installing any software on their PC. The scanned document goes to the SD card and the user’s PC looks at the scanner itself as if it is the SD card. Simple.
