5 Key Functions of Multifunction Printers (MFPs)

Multifunction printers, commonly referred to as MFPs or all-in-one printers, have revolutionized the way businesses and homes manage their printing needs. 

These versatile devices can print, scan, copy, and even fax documents, combining multiple office equipment into one compact machine. 

But how do these remarkable machines work? 

Let's delve into the inner workings of MFPs.

1. Printing Function

The core function of an MFP is printing, as the name implies. 


MFPs may use either inkjet or laser technology, each with a unique operation process.

Inkjet printers print by spraying small droplets of ink onto paper. 

The printer's control system directs the printhead where and when to release the ink based on the document's data. 

On the other hand, laser printers use a laser beam to produce an image on a photosensitive drum. 

The image attracts toner particles, which are then transferred onto the paper through heat and pressure.

2. Scanning Function

Scanning is another crucial feature of MFPs. 

The scanner uses a light source (usually a light-emitting diode or a cold cathode fluorescent lamp) that moves across the document. 

As the light reflects off the document, it hits a sensor array that converts the light into electrical signals. 

These signals are then digitized and stored in the computer as an image file.

3. Copying Function

The copying function is essentially a combination of scanning and printing. 

When you place a document on the scanner bed and select the copy option, the MFP first scans the document to create a digital image. 

This image is then sent to the printer component, which prints a replica of the original document.

4. Faxing Function

Faxing might seem outdated in the era of emails and instant messaging, but many businesses still use it for secure document transmission. 

When you feed a document into the MFP's fax component, the device scans the document and converts the information into audio frequency tones. 

These tones are transmitted over a phone line to another fax machine, which decodes the tones back into a document.

5. Connectivity and Control

Modern MFPs offer various connectivity options, including USB, Ethernet, and Wi-Fi. 

These connections allow the MFP to communicate with computers, smartphones, and other devices. 

The user sends a print command from their device, and the MFP's internal processor interprets the command and initiates the appropriate action.


Multifunction printers are marvels of modern technology, combining several essential office functions into one efficient device. They operate through a series of complex processes, from interpreting digital commands to deploying mechanical components. 

Understanding how these machines work can help users troubleshoot issues and better appreciate the technology they use daily. Whether you're a business owner seeking to streamline your office operations or a tech enthusiast curious about everyday gadgets, MFPs are a fascinating study of technological integration and innovation.
