CompTIA A+ Core 1 (220-1101) — Question 166

Users report that all copies produced on a copier have a solid black line, but printing is unaffected. Which of the following is the MOST likely cause?

Answer options

• A. Failing imaging drum
• B. A scratch on the scanning bed
• C. Bad output tray
• D. Damaged fuser

Correct answer: B

Explanation

The presence of a solid black line on copies typically suggests that there is a physical imperfection on the scanning bed, such as a scratch, which directly affects the copying process. In contrast, the imaging drum, output tray, and fuser are more likely to impact printing quality rather than the appearance of copies.
