As a high -tech product that integrates photoelectric and mechanical integration, the scanner has become a must -have for daily office and life with its unique digital "image" collection capabilities, low prices and excellent performance.Lets take a look at how to buy scanners with Xiaobian!
Introduction to scanner
The scanner is a digital input device that can be displayed, edited, stored, and output by capturing images and converting it into a computer.The principle of the scanner is to use photoelectric technology and digital processing technology to convert graphics or image information into digital signals by scanning.
Scanner use
The scanners three -dimensional objects such as photos, text pages, drawings, art drawings, photographs, Philippines, Filin soft films, and even textiles, sample panels, and printed board samples can be used as scan objects., Graphic physical converted into editing and adding files.The scanner is suitable for office automation (OA), and is widely used in signboard panels, printed boards, and printing industries.
(1) You can organize art and pictures in the document;
(2) Enter the printed text scan into the text processing software to avoid the trouble of re -typing;
(3) Scanned and entered the computer on the print version and panel samples, you can design and copy the board diagram on the board to solve the problem of copying the board and improve the efficiency of the board.
(4) The automatic entry, editing, and realization of Chinese character panels and complex icons can be realized by the printed sketching.
(5) Add images to multimedia products;
(6) Integrated visual information in the literature makes it more effectively exchanged and communicated.
Scanner classification
Platform/tablet style
Advantages: fast scanning speed, good quality, most commonly used disadvantages: large volume, limiting the area of ??scan files (A4 large)
Roller
Advantages: Establishing design, which can handle the disadvantages of various size files: slower than the platform type, the price is more expensive than the platform type, be careful when placing
Portable
Advantages: convenient, small volume, fast scanning speed disadvantages: scanning is relatively small
Gao Pianzi
Advantages: small volume, easy to carry, fast scanning speed, both printing function disadvantages: more expensive
Business card scanner
Advantages: small volume, convenient carriers, limited scanning speed, limited use, disadvantages: price is not cost -effective
Paper scanner
Advantages: can be automatically scanned in paper, good color treatment effect good disadvantages: can only be performed on a single page
Photo scanner
Advantages: High image quality, expensive prices of digital cameras, and disadvantages: can only handle photos
3D scanner
Advantages: Able to restore 3D scene scanning speed of high efficiency and high precision, disadvantages: expensive price
How to choose a scanner
Performance parameters
See the performance parameters first, including: scanning amplitude (size), optical resolution (mostly positioning at 600x1200 DPI and higher), color bits (the higher the number of digits, the richer the color), the light sensing element (CCD technologyAt present, the most mature and superior performance, CIS is suitable for mobile office environment).
Supporting software
Used users who are not familiar with graphics can choose to provide a simple scanner.There is a certain difficulty in choosing improper choice, and it is best to provide a more detailed Chinese instruction manual.The selection of OCR software is very important for office users. When choosing, pay attention to whether it can identify various printed handwriting, tables and whether they can identify mixed Chinese and English rows.
Common SCSI interfaces, EPP interfaces, and USB interfaces (USB1.1 and 2.0), fire lines (1394).It is recommended to buy a USB2.0 interface, fast speed, support is plug and play, which is very convenient to connect with the computer.
Machine detection
First look at the appearance, and then detect, including the test of the scanners adaptive ability, the sensitivity element, the transmission mechanism, the gray level, the color and the OCR text recognition input detection.
Brand selection
The scanner should choose a good quality and durable.The brands scanner is not only guaranteed, but also complete after -sales service.
