CompTIA A+ Core 1 (220-1001) — Question 178

A user reports a laserjet printer is not printing properly. A technician prints a test page and notices the toner is smeared on the page. The technician confirms the toner cartridge is installed correctly and the paper in the tray is the right size. Which of the following printer components is the MOST likely cause of the problem?

Answer options

• A. Fuser
• B. Roller
• C. Memory
• D. Toner

Correct answer: A

Explanation

The fuser is responsible for bonding the toner to the paper, and if it is malfunctioning, it can cause smearing. The roller primarily helps in feeding the paper and would not cause toner smearing. Memory issues typically affect print jobs not printing at all, and the toner itself is confirmed to be correctly installed.
