Visioneer RoadWarrior 4D Duplex Mobile Color Scanner

Get quality scans anywhere you take your mobile computing device

Visioneer's RoadWarrior 4D Mobile Scanner

The Printer / Scanner section of has looked at mobile scanners from three of the top imaging companies (Epson, Canon, and HP) recently, and while they all worked well enough, feature sets and capabilities were somewhat diverse. In addition, considering how small they are and what they’re capable of, unless you have an application that requires (or benefits from) the ability to setup and scan in seconds—no matter where you are—there are better choices. If you do need to scan on the road, though, here’s another good choice, the $149.99 MSRP RoadWarrior 4D Duplex Mobile Color Scanner from a Northern California company that specializes in scanners, Visioneer.

Design and Features

Since the RoadWarrior 4D pulls power through its mini-USB port, you must connect it to a computing device with a hot, or charging, USB 2.0 port. In other words, your laptop or tablet must have a charging USB port to use the scanner.

At 11.5 inches long, 2.6 inches wide, 1.6 inches tall, and weighing a slight 1.1 pounds, the RoadWarrior 4D isn’t much to carry. It’s smaller, in fact, than some competing models. Epson’s $179.99 (MSRP) DS-40 Color Portable Scanner, for example, measures 11.7 inches wide, by 2.8 inches from front to back, and only 1.7 inches tall, but it too weighs only 1.1 pounds.

Like most mobile scanners, this one has a OneTouch button on the machine itself. Typically, these buttons initiate the scan and, with instructions you provide beforehand, determine settings such as resolution and destination. The RoadWarrior 4D’s OneTouch software can send the scanned document in various formats to multiple locations, such as your hard drive, an email, the cloud. If the page is double-sided, the single-pass scanner scans both sides simultaneously.

Performance and Software

Compared to most other scanners in general, the RoadWarrior 4D’s daily duty cycle is low—100 pages. But then it’s not designed to be a volume workhorse. Instead, it’s designed to help you capture and organize data on the road, using as few resources as possible to do so.

Otherwise, it scanned my test documents and images plenty fast enough.

In addition, the RoadWarrior 4D comes with some of the industry’s best optical character recognition (OCR) and document management software, as follows:

  • Nuance OmniPage Pro: One of the first and most accurate OCR programs available, OmniPage Pro turns your scanned text into editable, formatted text.
  • Nance PaperPort: One of the industry standards in document management software.
  • Nuance Power PDF: This is, in effect, a PDF authoring tool similar in concept anyway to Adobe Acrobat, although not quite as powerful and developed.

Visioneer also throws in Visioneer Acuity, which, according to the company, “enables your scanner to instantly improve the visual clarity of the scan, plus auto-crop, auto-straighten and auto-rotate, all with the touch of a button.” This is a rather bold claim. Like most dust and scratches and other seemingly magic filters, Visioneer Acuity worked well on some problems and not-so-well on others, but it worked often enough to be useful.

The End

I’ve looked at a few of these mobile scanners, and it always amazes me at well these miniature devices work—especially their accuracy. The RoadWarrior 4D is no exception, and in that regard it hold up well to mobile scanners offered by Canon, Brother, HP, and Epson. In addition, it’s also the least expensive, and some cases by quite a bit.

To be fair, though, most of those also had batteries, in one form or another. The Epson WorkForce DS-40, for example, uses AA batteries, but then it supports Wi-Fi and therefore is not dependent upon USB for power.

In any case, the Visioneer RoadWarrior 4D is a great little scanner, well worth the price.
