Scanners are important equipment for obtaining high-quality images in OCR. Earlier we introduced flatbed scanners and also briefly mentioned paper-fed scanners. So, what kind of scanner is a paper-fed scanner? What does it look like?
Automatic Document Feeder (ADF) is a scanning device specially used to process large quantities of paper documents. It allows users to continuously place multi-page documents into the device for scanning without having to manually work page by page.
Paper-fed scanners usually consist of the following parts:
1. Automatic document feeder (ADF): This is the core component of a paper-fed scanner. The ADF is usually located on top of the scanner and has a lid that opens and closes. Users can put paper into the input slot or paper tray of the ADF, and then the paper will be automatically fed into the scanning area through a mechanical device for scanning.
2. Scanning sensor and light source: Paper-fed scanners are equipped with optical sensors and light sources to detect and capture the image content on the paper. The optical sensor is responsible for acquiring the image, while the light source provides the necessary illumination.
3. Control panel and buttons: Sheet-fed scanners usually have a control panel and buttons on which users can adjust scan settings, start scanning, select target file formats, and other operations.
When using a paper-fed scanner, users only need to place paper into the feed slot of the ADF and start the scanning process through the control panel or buttons. The device automatically grabs the paper from the feed slot and scans the contents of the paper using sensors and light sources. After the scan is completed, the scan results can be obtained on your computer or other storage device.
Paper-fed scanners are widely used in office environments, corporate document management, file archiving, and various scenarios that require processing large amounts of paper documents. It provides an efficient, fast and convenient way to scan and digitize large quantities of documents, saving a lot of labor and time costs. #Automated 3D Scanner#
