What Type of Data Does a Scanner Handle?


Scott Campbell

Scanners are incredibly useful devices that allow us to convert physical documents into digital format. They work by capturing an image of the document and then converting it into a digital file that can be stored, edited, and shared.

But have you ever wondered what type of data a scanner handles? Let’s dive into it!

The Basics

Before we discuss the specific types of data that a scanner can handle, let’s cover some basics. Scanners are primarily designed to capture two types of data: text and images. These two types of data can be further classified based on their characteristics and the way they are handled by scanners.

Text Data

When it comes to text data, scanners are capable of handling both printed and handwritten text. They use optical character recognition (OCR) technology to convert the scanned text into editable and searchable digital text. This means that you can easily copy, paste, edit, and search for specific words or phrases within the scanned document.

Image Data

In addition to text, scanners also handle image data. This includes photographs, illustrations, diagrams, signatures, and any other graphical elements present in the document. Scanners capture these images with great precision and detail, ensuring that the digital version closely resembles the original document.

Types of Documents

Scanners can handle a wide range of documents, each with its own unique characteristics. Let’s take a look at some common types:

Text Documents

This category includes printed documents such as letters, contracts, invoices, reports, and more. Scanning these documents allows you to create digital copies that can be easily archived or shared electronically.

Newspapers and Magazines

If you’re interested in preserving articles or stories from newspapers or magazines, scanners come to the rescue. You can scan these documents and save them as digital files, making it easy to access and share them with others.


Scanners are also handy when it comes to digitizing books. Whether you want to preserve an old book or create an electronic version of a new one, scanners can capture the pages and convert them into readable digital files.

Additional Features

Modern scanners offer a range of additional features that enhance their capabilities. These features include:

Resolution Control

Scanners allow you to adjust the resolution at which the document is scanned. Higher resolution results in more detailed images but also increases file size.

Color Depth

You can choose whether to scan documents in color or black and white. Color scanning is ideal for capturing photographs or colorful illustrations, while black and white scanning is often preferred for text documents.

Duplex Scanning

Duplex scanners have the ability to scan both sides of a document simultaneously, saving you time and effort when dealing with double-sided documents.

In Conclusion

In summary, scanners are versatile devices that can handle various types of data. They excel at capturing both text and image data, allowing you to create digital versions of physical documents with ease. Whether you need to convert text documents, preserve newspapers or books, or digitize photographs, a scanner is an essential tool in today’s digital world.
