CompTIA A+ Core 1 (220-1001) — Question 162

A user is having difficulty using a personal all-in-one printer. When the user scans a single-page document in flatbed mode, the scan appears correctly; however, when using the printer's document feeder, the scan has a vertical line going across the page. Which of the following should a technician perform FIRST to resolve this issue?

Answer options

• A. Replace the printer's ADF.
• B. Install a pickup roller replacement kit.
• C. Clean the separation pad.
• D. Use a microfiber cloth to clean the glass.

Correct answer: B

Explanation

The correct answer is B, as a faulty pickup roller can cause paper misfeeds or improper feeding, leading to scanning issues like vertical lines. While cleaning the glass (D) or separation pad (C) are helpful maintenance tasks, they are not the primary solution for the specific document feeder problem. Replacing the ADF (A) is also unnecessary if the issue is related to the pickup mechanism.
