CompTIA A+ Core 1 (220-1101) — Question 18

Several users who share a multifunction printer in an office have reported unintended, thin, vertical lines that cover the entire height of every page printed from the printer. Which of the following steps should a technician complete in order to MOST likely resolve this issue?

Answer options

• A. Replace the printer paper with a new ream.
• B. Clear the print spooler on each computer.
• C. Reinstall the printer driver on each computer.
• D. Perform the drum-cleaning procedure.

Correct answer: D

Explanation

Performing the drum-cleaning procedure is the most effective way to address the issue of vertical lines on printed pages, as it directly targets the printer's drum, which may be dirty or malfunctioning. Replacing the printer paper, clearing the print spooler, and reinstalling the printer driver are unlikely to resolve print quality issues related to the drum itself.
