What is a Laser Printer?

 

Since laser printers have become more economical to purchase, they have become common place in both large and small businesses and also home offices. Laser printers offer long term value for money, with higher capacity toner cartridges and lower ‘price per page’ printing than inkjet printers.

 

Although many people use laser printers in their day to day office lives, few know or think about what takes the text or image from your computer screen to the finished printed document, but here’s how it works:

 

Within the printer there are a few key components that bring the science together to make a printed document:

 

  • The toner cartridge houses the loose toner powder, an individual cartridge is inserted into the printer for each colour (black, cyan, magenta and yellow). Your printer will tell you when each cartridge needs to be replaced.

 

  • The drum unit, with the help of static electricity, is responsible for transferring the toner on to the paper in the form of text or image.

 

  • The fuser unit is responsible for heating the toner, melting the plastic polymer content and applying pressure to fuse it to the paper.

The drum is given a positive charge by the corona wire or charging roller. While the drum rotates, a laser shines over the surface after being deflected by a rotating mirror, drawing the image on and negatively charging points of the drum to form the image to be printed. Once the negatively charged image is in place, the drum rotates and passes by the developer roller which is loaded with positively charged toner powder. The negative charge of the drum attracts the toner which sticks to it. The drum continues to turn and deposits the toner powder on to the positively charged sheet of paper that is being moved through the machine by the roller assembly. The paper then passes through the heated fuser rollers, which melts the toner to bond it to the paper surface. Once the drum has deposited the toner powder on to the paper, the drum surface is cleaned by the drum cleaning blade and in some machines passes the discharge lamp which erases the electrically charged image and the process begins again.

 

Benefits of a Laser Printer…

 

  • Low price per page due to high yield toner powder
  • Fast printing speeds for monochrome and colour printers
  • Sharp text and images, no risk of smudging or bleeding ink
  • Quiet operation, beneficial in a busy office
 

On the other hand…

 

  • Initial outlay can be high as laser printers and cartridges are quite expensive
  • Laser printers are quite bulky therefore take up more space, however, they are getting smaller and lighter with every new model.
  • There are more components to replace, not only toner cartridges, but drum units and fuser units will also need replacing at some point.
