You are troubleshooting a laser printer in the office. Users are complaining that while the printer seems to be functioning, the output is smearing easily. Which laser printer component is malfunctioning?
  1. The Transfer Corona Wire
  2. The Fusing Assembly
  3. The Print Drum
  4. The Laser
Explanation
Answer: B - If printer output is easily smearing on a laser printer, most likely the fuser assembly is malfunctioning.

Key Takeaway: The fuser assembly is responsible for fusing the toner to the paper by passing it through a heating element that can reach 400 degree F. If this component is not functioning properly, the toner will easily smudge off the paper. If the transfer corona wire or laser were faulty, there would be no image at all, and a failure in the print drum would in paper jams and vertical/horizontal lines.
