We usually when in contact scanner, often encounter many arcane technical terms: optical resolution (optical resolution), the maximum resolution (maximum resolution), color resolution (color depth), scan mode, the interface mode (connection interface) and the like. I will introduce the basic knowledge of these scanner, giving readers popularize knowledge about the scanning gun. So that we can better understand the scanner, when we buy scanner can be used as a reference. First we need to know what the resolution. Various types of scanner are marked its optical resolution and maximum resolution. Resolution unit is dpi, dpi is the abbreviation of the English Dot Per Inch, meaning the number of pixels per inch. After understanding the meaning of the resolution of radium code scanner, let us look at the following parameters of these scanner important to us how much. Optical resolution is the actual optical scanner system information can be collected, that is, the resolution of the scanner of the photosensitive member. For example, the maximum scan range of the maximum width 216mm × 297mm (for the A4 paper) of the scanner can scan for 8.5 inches (216mm), which contains a photosensitive original scanner unit 5100, the optical resolution of 5100 ÷ 8.5 英寸= 600dpi. Common optical resolution is 300 × 600dpi, 600 × 1200dpi, 1200 × 2400dpi or higher.
