Utilizing a large-format scanner is a superb way to handle the acquisition or archiving of pictures, books, and other documents. Those looking to buy wide-format scanner units, though, may end up wondering what distinguishes one system from another. If you're in the market to buy large-format scanner systems, you'll want to pay close attention to these four areas of interest.

Sensor Technologies

There are two basic ways a scanning system can acquire an image. The first is using what is called a contact image sensor, frequently referred to as a CIS. If you have a flatbed scanner or a multifunction printer that does scanning, you're familiar with this sort of setup. In the case of dealing with wide-format materials, you'll simply be working with a much larger configuration. These models are considered ideal for handling photos and other kinds of images that require high fidelity in terms of colors and details.

A charge-coupled device, often called a CCD, operates more like how the image sensor in a digital camera works. These are more commonly employed in scanning drafting documents, technical specs, patents, and other products that require contrasting line precision. They're also frequently used for acquisition of texts.

Media Loading

Virtually all systems on the market can handle the loading of standard papers and cardstocks. If you're trying to scan something thicker, such as a painting, you may need to look into a system that accepts thicker media. At a certain stage, you'll likely have to employ a CCD scanning system that has a sensor at a point away from the media in order to do the job well.

LED vs. Other Light Sources

Particularly when scanning thousands or millions of documents, operating cost becomes a factor. When looking at models that operate cost-efficiently, it's a good idea to check whether they employ LED sources. These will help you to cut down on electric costs.

Instant-On Capability

Especially in a production or office environment where a system is being utilized all day, you want to know that it'll turn on instantly. Some units have power-saving features that cool the lamp off when the setup is not in use. If you're worried about having immediate access to the scanner at all times during the workday, look for one that has an instant-on function. Once it has been turned on in the morning, the lamp won't require a warm-up period.
