What component in a laser printer applies heat to fuse the toner onto the paper?
Transfer belt
Fuser assembly
Pickup rollers
Imaging drum
Transfer roller
Duplexing assembly
The fuser assembly is the correct answer because it's responsible for heating the toner powder, allowing it to melt and bind to the paper to create a permanent image. The imaging drum is what receives the image from the laser in preparation for applying toner, but it does not fuse the toner to the paper. The transfer belt also is involved in the imaging process as it transfers the toner from the drum onto the paper, but again, it doesn’t provide the heat to fuse it. The transfer roller helps to apply an electrical charge to the paper, enabling the toner to be pulled onto the paper from the drum. Pickup rollers are responsible for feeding paper into the printer, and separation pads help separate individual sheets of paper. A duplexing assembly allows for printing on both sides of the paper but has no role in fusing toner.
