Introduction

Multifunctional devices combine the functionality of several different pieces of office equipment into a single machine. Instead of purchasing a separate fax, copier, scanner, and printer, offices can buy a single machine to perform all these functions.

How MFDs Work
Multifunctional devices (MFDs) combine several core technologies, including image scanning, document printing, and fax signaling, into a single unit. Depending on how the technologies are combined, a multifunctional device can perform a variety of functions. For example, connecting an MFD to a computer allows you to scan and print. If you scan a document and then print the resulting digital image, the MFD acts as a copier. And by scanning, printing, and using fax software, the MFD can serve as a fax machine.
