What you should look for when buying a document scanner depends on what you’ll be doing with it. If you’re tackling photos, you’ll want to look for the highest definition (6400 DPI) available and a scanner that can take on a variety of image sizes. If you’re doing a moderate amount of document scanning, you should prioritize a scanner that can identify and organize documents. If you’re doing office-level scanning you’ll want an automatic feeder, the ability to scan a wide array of documents and photos, and blazing fast scan speeds. The fastest scanners can do hundreds of pages a minute but they carry a higher price tag.
