Each company does things a little differently, though, so you'll need to follow the manufacturer's instructions to set up the connection. In the article above, we've detailed which connections are available for which models. Many will connnect wirelessly to your phone or tablet too. Most document scanners can be connected to a computer via USB, Wi-Fi, or Ethernet. How do I connect a scanner to my computer? This can then be transferred to a computer or phone, or in the case of a multifunctional device, printed out directly. The sensor converts these readings into data, which is then processed to create a digital image. Scanners typically use a combination of an internal light source and a moving image sensor, such as a charge-coupled device (CCD) or a contact image sensor (CIS), to capture an image.Īn internal light illuminates the object being scanned as the sensor moves across the object, taking multiple readings at different point. They typically connect to your computer or phone, either wirelessly or via USB. There are several types, including flatbed scanners, sheet-fed scanners, hand-held scanners and drum scanners, but they all work using similar principles. What is a scanner?Ī scanner, also known as an image scanner, is a device that captures images of documents, photos, and other objects and converts them into digital form. And the app makes it easy to scan directly to PC, network, cloud services and email. But on the positive side, it’s lovely and portable, at less than a foot long and weighing just over a pound. Want a portable document scanner, and don't want to pay much for it? Then you'll be pleased by the price of the Brother DS-640. Admittedly, it's pretty basic, feature wise: it’s not suitable for photos, there’s no Wi-Fi or automatic document feeder, and the maximum resolution is fairly low at 300dpi. So while it would be overkill for a home office, it's a great choice for any workplace where a lot of scanning is the norm. In short, this is very much the Rolls Royce option of document scanners, with a price to match. The 2.7-inch touchscreen provides easy access to scan jobs, settings, and maintenance features, and you can use on-board software to turn scans into searchable PDFs. You can scan folded pages, plastic cards, sealed envelopes, passports, and more, and resolution goes up to 600 dpi. Double-feed detection prevents missing pages from being scanned, and there's a slow mode for delicate sheets too. When it comes to normal letter-sized documents, it scans in both black-and-white and colour at a speedy 70 ppm in simplex mode and 140 ipm. And that's not all: in long scan mode, it scan documents up to a whopping 12 x 220 inches (30.48 x 558.8 cm). A duplex ADF scanner with tray that holds up to 120 sheets at a time, the DS-30000 Large-Format Document Scanner can capture scans as small as 2 x 2 inches (5.08 x 5.08cm) and as large as 12 x 17 inches (30.48 x 43.18 cm). If you regularly scan huge numbers of documents, including at large-format sizes, you'll love this scanner from Epson. It works quickly, too, zipping through a steady 35 pages per minute. Other scanners on the market can beat some or all of these specs, but they're more expensive, and overkill for most people's needs. And it can also scan both side of each page if you wish. It has a capacity of 50 sheets, so you can leave a big report to scan without constantly reloading pages. It comes with Wi-Fi connectivity, scans text accurately, and reproduces all kinds of media well, from business cards to photos, thanks to its high resolution of 1200dpi (dots per inch). If you don't need Wi-Fi connectivity, though, you may prefer the otherwise identical (and cheaper) Epson WorkForce ES-400 or the Canon imageFORMULA R40 (below). If so, we'd recommend the Epson WorkForce ES-500WII. Need to digitize long reports, or lots of individual documents? Then you want a scanner with an automatic document feeder (ADF), which allows you to add a bunch of pages at once, and leave the scanner to get on with it.
