CompTIA A+ Core 1 (220-1001) — Question 274

A technician is repairing a laser printer because its print jobs have a narrow, faded line running along the length of the page from top to bottom. The faded line is always in the same place. Which of the following will MOST likely resolve the issue?

Answer options

• A. Empty the excess toner bottle.
• B. Update the printer firmware.
• C. Replace the corona wire.
• D. Replace the transfer drum.

Correct answer: D

Explanation

Replacing the transfer drum is the most likely solution because a worn or damaged drum can cause consistent fading along the length of the page. Emptying the excess toner bottle, updating the firmware, or replacing the corona wire would not specifically address the issue of a permanent faded line in the same location.
