Guangzhou State Association - scanner (recommended), scanning gun wholesale, scanner provided by the Guangzhou State Association. We are Guangzhou City State Association Information Technology Co., Ltd. (www.gzdb899.com) located: Guangzhou specializes in: cash register, scanner, bar code machines, management software, small ticket machines, cash registers, shredders we usually when in contact with what brand supermarket scanner scanner is good, 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 so on. 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, let us look at the following parameters of the scanner to us how important it is. 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 contain 5,100 photosensitive elements of the original, the optical resolution of 5100 ÷ 8.5 英寸 = 600dpi . Common optical resolution is 300 × 600dpi, 600 × 1200dpi, 1200 × 2400dpi or higher. Ma Jie MS5145 one-dimensional laser scanner with the more common shell ABS plastic material, shape and ergonomic grip shape designed to fit to take. In performance, the use of Metrologic's most advanced scanning technology, pda scanner compared with conventional CCD scanners, scanning depth Ma Jie MS5145 scanner wholesale longer, wider scan area, the farther the distance from the bar code scanner , the wider the width of the scan lines. With Metrologic's other target sensor using infrared scanners different, MS5145's CodeSense to its normal operating state will set the laser pulse flashing type, when aligned with a barcode scanner, laser line will automatically switch to the long bright mode to facilitate Users scan only simplifies the operation, but also improves the efficiency. Besides the laser flash mode due to shortened working hours continuous laser head, so the scanner to work longer hours, and higher reliability.
