Asiakirjansyöttölaite

Asiakirjansyöttölaite, also known as a document scanner or document imager, is a hardware device that captures images of documents. These images are then typically converted into digital files, such as PDFs, JPEGs, or TIFFs. This process allows paper documents to be stored, accessed, and shared electronically.

Document scanners vary widely in their capabilities and form factors. Small, portable scanners are designed for individual users or mobile professionals, while larger, high-volume scanners are used in office environments for bulk scanning. Multifunction printers often include integrated document scanning capabilities.

The scanning process involves passing a document through the device, where light is shone onto the page and reflected light is captured by an optical sensor. This sensor converts the light into an electrical signal, which is then processed into a digital image. Resolution, color depth, and scanning speed are key specifications that determine a scanner's performance.

Document scanners are essential tools for digitization efforts, enabling businesses and individuals to reduce paper clutter, improve document retrieval times, and enhance data security. They play a crucial role in workflows such as archiving, record management, and digital transformation initiatives.
