Document scanners play a crucial role in any office. These devices process and deliver images to a computer where they’re converted into a data file. It’s an invaluable resource for bookkeeping, storing financial documents, and sharing physical content. Below is everything you need to know about how these devices work and the benefits you can expect when you invest in one.

How Document Scanners Work

The concept of document scanners was first developed in the mid-1800s. The system used a series of electromagnets to capture and reproduce basic images like handwriting, signatures, and drawings. This led to the development of photocell scanners in the early 1900s. These devices scanned data and then transmitted it over phone lines—a system that was used for decades and is the foundation for modern printers.

There are several types. Flatbed scanners shine a bright light beneath a document and capture the image based on the intensity and color of the light’s reflection. It then sends the image to a computer wirelessly or through a USB cable. These devices are best for simple opaque images and text documents.

Sheet-fed scanners work similarly, though the document is actively drawn from a tray and passes over a light and translucent surface that captures the image. These don’t capture the same quality as flatbed printers, though work much more quickly since sheets are auto-fed into the scanner.

Drum scanners are the most sophisticated. These systems capture highly detailed images by reflecting an image and capturing it similar to a camera. It uses an analog light to detect fine color details. While larger and more expensive, these scanners are the industry standard in marketing, publishing, photography, and related fields.

The Benefits of a Multifunctional Device
