The laser printing process is an advanced process that is much more intensive than inkjet printing, in which ink is just sprayed on paper. When an image is sent to a laser printer, a roller begins to spin to build up static electricity. A laser then places the to-be-printed image or text on the roller, so it is electronically grafted on the roller. Toner is then released, and the roller attracts toner in the shape of the image. Paper passes by the roller and finishes the laser printing process by picking up the toner.

Laser printer.

After the user sets a document to print, the laser printing process begins by making an internal roller spin. This spinning causes the roller to build up static electricity, which is needed for later parts of the laser printing process. At this stage, the roller does not have anything on it; it is just a blank piece of equipment. Another way the roller builds up electricity is through light, because the roller also is photoconductive.

Lasers come into play next, as a laser is responsible for disrupting the static electricity and causing a reaction with the toner later. The laser contains a negative electrical charge, and it temporarily grafts the image on the roller. This negative charge is very important because, otherwise, the rest of the printing process would not work correctly. This image will disappear after the laser printing process is complete, allowing the roller to take on another image.

Toner — black and color — is released according to the image being printed. For example, if a magenta image is being printed, then magenta toner will be released. The toner has an opposite, or positive, charge that is attracted to the parts of the roller that the laser touched. This means an exact duplicate of the printed image is now printed on the roller. In most cases, the toner will wipe off very easily.

Paper is then introduced as the last step of the laser printing process. The paper is given a negative charge as it passes through the printer but, because the charge is stronger than that on the roller, the toner lifts from the roller and goes onto the paper. This results in the paper taking on the image and leaving the printer. After this, a strong light shines on the roller to erase the grafted image, so a new image can be grafted onto it for the next print.

Throughout the decades, laser printers have become so efficient and affordable that they have become a staple in almost every office environment. Numerous workplaces across various industries tend to favor laser printers over inkjets for their printing needs. 

Most people know what they get from a laser printer: a quiet and reliable machine that can print large volumes of high-quality documents with exceptional speeds. However, only a handful of users know exactly how a laser printer works.

If you’re curious about how documents go from screen to page using a laser printer, you came to the right place. We’ll explain to you in detail how a laser printer works and the key steps involved in the process. And if you’re in the mood for reading, we at YoyoInk have also prepared a brief overview of the types of laser printers, a breakdown on the advantages and disadvantages of a laser printer, and a discussion on whether a laser printer is better than an inkjet.

How a Laser Printer Works: YoyoInk Explains

After the computer sends your print file to the laser printer, the latter beams, an outline of your print job on a metal cylinder drum. The drum draws out fine toner powder from its cartridge through static electricity and then rolls the powder into the paper in the form of your print outline. The heat generated from a fuser melts and embeds the toner powder pattern onto the paper as it slides through the printer. The laser printer ejects the final printout, and the process is complete. 

Step by Step Working Process

We have just talked about how a laser printer works using heat, static electricity, toner, and moving parts to create your desired print. However, numerous other moving parts and components work harmoniously inside a laser printer to create your final document or photo. Here’s how a laser printer works step by step:

Step 1: Image Processing

Once you click on the print command on a certain document or image, the computer immediately sends the information to the laser printer’s internal memory. Here, the printout data is stored and prepared for processing.

Step 2: Charging

The laser printer starts warming up. The corona wire heats up and gets ready to transfers its positive static charge to the metal cylinder drum. 

Step 3: Exposing

While the drum rotates, it receives a positive charge throughout its entire surface. Some laser printers, particularly all-in-one color models, have four drums, catering to each color: Cyan, Magenta, Yellow & Black. A laser is then activated and beamed to a chain of mirrors and reflected throughout the drum surface. The reflected laser beam creates an outline of your print through an opposite negative electrical charge.

Step 4: Developing

Positively charged carbon toner powder is gradually released from the toner cartridge onto the drum while it rolls. The positively charged toner powder sticks to the negatively charged, laser beamed areas since opposite charges attract (static electricity). Meanwhile, positively charged areas on the drum are left without any trace of toner.  

Step 5: Transferring

The paper or media slides across the printer and receives a positive charge via the transfer belt. While it moves through the drum, the negatively charged toner gets drawn to the paper’s surface and conforms to your print outline.

Step 6: Fusing

Heated rollers called the fuser unit melts the toner onto the paper. Your document or image is imprinted into the page and is then ejected from the printer as the final printout.

Step 7: Cleaning and Recharging

Before the drum completes its revolution, it is subjected to an electrically neutral soft plastic blade and cleaned from residual toner. The excess toner is then deposited into a waste reservoir. Finally, the newly cleaned drum receives a fresh negative charge on its surface from a charge roller, preparing it for another laser beam round.

Types of Laser Printers

Laser printing technology was first invented in 1969 by Gary Starkweather during his time with the product development team of Xerox. Since then, laser printers have made their way into the workplace, evolving into highly efficient printing machines for large and small industries. Today, you will generally find three types of laser printers: monochrome, color, and multifunction.

(a) Monochrome Laser Printer

The simplest of all laser printers is the monochrome model, which prints in black and white. They are cheaper than color laser printers and only need black cartridges to work. There are various monochromes laser printers available in the market designed to cater to different consumer needs and preferences.

If you’re looking for the best budget-pick, there’s the Brother HL-L2350dw with its $100 pricing alongside a 32 page per minute print speed and a paper tray that can house 250 sheets. And with its TN760 toner cartridge and DR730 drum unit, you can print more than 4,000 pages before running out.

(b) Color Laser Printer

Laser printers were originally built exclusively for monochrome (black and white) printing, and it’s only recently that models capable of printing in color were made. Today, however, the laser color printer has become an increasingly popular choice in office environments due to its practical advantages and reliable performance. The best laser printer models can give you unrivaled printing speeds and efficiency and allow you to take on high-volume projects with ease. They are also cheaper to maintain in the long run than inkjet printers.

(c) Multifunction Laser Printer

Multifunction laser printers combine numerous devices, including a copier, fax, printer and scanner. Also known as “all-in-one printers,” these laser printer models give you unmatched convenience for everyday scanning and faxing operations at home or the office. It’s the ideal option if you’re looking for a versatile printer that gives you all the advantages of laser printing.
