The Basics Of A Printer Fuser

What is a laser printer fuser and how long will it last? If you are looking for the answer, we have got it for you. The fuser is a key component of laser printers. We wouldn’t be anywhere without the pressure and heat of the fuser. Laser printers require a fuser, which is basically two heated rollers that are there to melt the toner powder onto paper. Read on to learn more about the basics of a printer fuser!

What is a Printer Fuser?

Laser printers that can print on only one side of paper come with a fuser that has one heated roller. The second roller is a pressure roller that pushes the paper onto the heated roller. A laser printer that is able to print two-sided will come with a fuser that has two rollers. Both rollers will melt the toner powder onto the two sides of the paper at the same time.

How Does a Fuser Work?

Towards the end of the printing process, the paper will pass through the fuser after the toner powder is placed on the paper.

The Fuser Rollers

In the fuser melting process, the paper goes through the rollers of the fuser unit. You will find that the heated top roller melts the toner into the paper. Meanwhile, the roller that the bottom might be heated up too. The bottom roller is often a solid tube that has a rubber coating. Clean the fuser rollers using a clean, lint-free cloth. Make sure the fuser has completely cooled before handling it.

Heater Lamp

The heated roller is hollow and it will come with a heating element inside of it. If the heater lamp needs to be replaced, you will receive an error message. You can tell if the heater lamp has stopped working as the printer fuser will not get hot. The heater lamps are some of the most common fuser parts to fail.

Thermistor

The thermistor controls the heat that is inside the fuser. You can use a cotton swab to clean the toner off the thermistor.

Thermostat

You will also find a thermostat in the fuser that prevents it from overheating. Clean the surface using a clean, dry cloth.

When Do I Replace the Fuser?

Fuser units will have to be replaced after they are used often. Most laser printers will tell you when the fuser unit has to be replaced. One way to tell when a fuser unit needs to be replaced is when there is smearing or smudging on your printout. This happens because the fuser does not heat the toner particles enough to completely melt them onto the page.
