Which of the following best describes the function of the fuser in a laser printer?

It melts the toner onto the paper
It transfers images to the drum
It cleans the drum
It cools the printer after use

The correct answer is: It melts the toner onto the paper

The fuser in a laser printer is a critical component designed to permanently bond the toner to the paper. It achieves this by using a combination of heat and pressure, which essentially melts the toner particles, allowing them to adhere to the paper's surface. This process ensures that the printed image is durable and resistant to smudging. While there are other components in a laser printer that serve different purposes—such as transferring the image from the drum to the paper or cleaning the drum after printing—the fuser specifically focuses on the final step of the printing process: securing the toner onto the paper to create a lasting print. This distinction is important to understanding how laser printers operate and the role each component plays in achieving high-quality prints.
