Computer scanners are devices used to digitize physical documents and images into digital formats that can be stored, edited, and shared electronically. They work by using sensors to capture the image or text on the document and converting it into a digital file. Scanners can be flatbed, sheet-fed, handheld, or specialized for specific types of documents like film or slides. Flatbed scanners are the most common type of scanner and are similar in appearance to photocopiers. They have a flat glass surface where the document is placed face-down and scanned. Sheet-fed scanners, on the other hand, are designed to scan multiple pages at once and are commonly used in offices for document management. Handheld scanners are portable and can be used to scan documents on the go, while specialized scanners are used for specific types of documents like film or slides. Scanners are commonly used in offices, libraries, and homes to digitize documents, photos, and artwork. They are also used in industries like healthcare, where they are used to scan medical records and images for diagnosis and treatment. In recent years, scanners have become more advanced with features like automatic document feeders, duplex scanning, and OCR (optical character recognition) technology. OCR technology allows scanned documents to be converted into editable text, making it easier to search and edit documents.
