A scanner is a device that converts physical documents, images, or objects into digital data or electronic format. It is commonly used to create digital copies of printed documents or to capture images for various purposes. Scanners work by capturing an image of the document or object using optical sensors and then converting that image into a digital file that can be stored, edited, or shared electronically.
Flatbed Scanners: These scanners have a flat glass surface on which you place the document or image to be scanned. The scanner’s sensor moves underneath the glass to capture the image. Flatbed scanners are versatile and can handle various document sizes.
Sheet-fed Scanners: These scanners are designed to handle multiple pages at once. You feed a stack of documents through the scanner, and it processes each page individually.
Handheld Scanners: Portable and lightweight, handheld scanners can be moved manually over the surface of the document or image to capture the data. They are suitable for scanning small or irregularly shaped objects.
Drum Scanners: These scanners use a rotating drum to scan images. They are known for their high-quality scanning capabilities, especially for professional graphic design or photography work.
Document Scanners: Document scanners are optimized for quickly scanning large volumes of documents, typically in office environments.
