A user reports that the printouts from a laser printer have lines and smudges on them. The printer is also intermittently misfeeding the paper. Which of the following components should a technician replace to address this issue?
Correct Answer: B
Comprehensive and Detailed In-Depth Explanation:
A maintenance kit for a laser printer often includes rollers, fuser, and other parts that wear out over time.
If the printer is smudging and misfeeding, it's a sign that multiple components are failing, which a maintenance kit is designed to resolve.
* Option A (Fuser): May cause smudging if it's not heating correctly, but it won't resolve paper misfeeds alone.
* Option C (Corona wire): Can cause poor image quality if dirty but doesn't affect paper feeding.
* Option D (Toner cartridge): Can cause streaks if defective, but not paper feed issues.
