CompTIA A+ Core 1 (220-1101) — Question 426

After a heavily used color laser printer was serviced to remove excessive dust, the image quality decreased. Which of the following should a technician most likely check on the printer?

Answer options

• A. Toner
• B. Calibration
• C. Fuser
• D. Drum

Correct answer: D

Explanation

The drum is critical for image quality as it transfers toner onto the paper. If the drum was not properly cleaned or is damaged, it can lead to poor print results. The other components, while important, are less likely to be directly affected by dust removal and would not typically cause a decrease in image quality in this context.
