Nearly as important as whether a portable scanner accepts one or multiple pages is whether it has two sensors, one for each side of a two-sided page. If you don't need an ADF, there's no reason to shell out for one. Manual-feed scanners cost less than their sheetfed counterparts, sometimes a lot less. A few have lower capacity.Ī substantial majority of portable scanners, such as PCMag favorites the Epson DS-80W and Brother DSmobile DS-940DW, are manual-feed or single-sheetfed machines. Most of these, including the Editors' Choice award-winning Epson WorkForce ES-300W, the Brother ADS-1250W, and the Epson WorkForce ES-300WR Accounting Edition, come with ADFs that hold up to 20 pages. If you'll do lots of scan jobs consisting of more than three pages, you should opt for a sheet-fed model. Portable scanners come in two basic flavors: manual-feed models (left) accept only one sheet at a time, while sheetfeds (right) accept multipage scan jobs, usually up to 20 sheets. Sheetfed scanners come with ADFs for scanning multipage documents. Manual-feed portables accept only one sheet, be it one- or two-sided, at a time. Portable scanners come in two basic types: manual-feed and sheetfed. Let's take a closer look at what features make specific types of portable scanners best suited for particular tasks. On the other hand, if you mostly scan invoices, sales receipts, applications, and other short documents, a more costly portable with a 20-page automatic document feeder (ADF) may be overkill. If you're scanning documents, you'll need good optical character recognition (OCR) to turn printed pages into editable text if you scan at high volume, you'll want to consider the scanner's duty cycle, which is the recommended number of pages it can scan per day, week, or month. Frequent business travelers will need to balance wanting the smallest and lightest scanner with the need for particular features such as two-sided scanning, high resolution, and high scanning speed. Many factors to consider come into play when choosing a portable scanner. Truly wireless scanners transmit data to your computer, phone, or tablet over Wi-Fi, and some support memory cards that allow you to scan without a computing device of some sort present. A few have batteries, and others get their juice via a USB tether to a desktop PC or laptop. Most portable scanners don't need to be plugged into an AC outlet to function.
