CompTIA A+ Core 1 (220-1101) — Question 419

A technician is troubleshooting poor printing quality on an inkjet printer. The pages have white lines running through the text and graphics. Which of the following is the most likely cause?

Answer options

• A. Worn out rollers
• B. Clogged printhead
• C. Faulty ink cartridges
• D. Poor quality paper

Correct answer: B

Explanation

The correct answer is B, as a clogged printhead can prevent ink from being applied properly, resulting in white lines in prints. While worn out rollers (A) can cause feeding issues, they are less likely to create white lines. Faulty ink cartridges (C) could lead to inconsistent color but are not specifically linked to white lines, and poor quality paper (D) typically affects the finish rather than creating gaps in the print.
