[2021 Edition] Which Scanner is Recommended? How to Use, How to Choose, and Popular Rankings

What is a Scanner?

A scanner, as you may know, is a device that captures printed text, images, or photos on paper as digital images and transfers them to a computer. It allows you to easily convert accumulated photos and paper documents into digital data, helping you organize your surroundings and save space. Not only is it useful for sharing with colleagues or friends via email or social media, but also for making copies. Along with PCs and smartphones, it is becoming an essential piece of equipment. Once you start using it, you’ll find it incredibly convenient, though it often gets overshadowed by printers. In this article, I’d like to introduce the different types of scanners and their appeal.

The Difference Between Scanners and Multifunction Printers or Copiers

Although It's Called a Scanner, There Are Actually Different Types.

Broadly speaking, there are two main types of scanners: multi-functional devices combined with printers and single-function scanners dedicated to scanning. Multi-functional devices are more commonly available, but dedicated scanning machines offer higher precision. Types of dedicated scanners include flatbed scanners, which are ideal for illustrations and diagrams, stand scanners for thick books, handheld (mobile) scanners, transparent scanners for film, and those specialized for business cards. It's a good idea to choose based on your intended use, frequency of use, and purpose.

How to Use a Scanner

The basic operation common to all scanners is to use the scan head to read the item you want to scan. For most models, you need to download the driver software and set it up and operate it from your PC. The format of the scanned data, resolution, storage methods, and various correction functions to enhance the image quality vary greatly depending on the model. Therefore, learning how to utilize these features is the key point.
