CompTIA A+ (220-901) — Question 16

A computer technician is responding to a call about a printer that is causing streaks to appear on every printout. Which of the following is the MOST likely cause?

Answer options

• A. Duplex unit
• B. Toner cartridge
• C. Imaging drum
• D. Pickup rollers

Correct answer: C

Explanation

The imaging drum is responsible for transferring toner to the paper, and if it's damaged or worn out, it can cause streaks on the printouts. The toner cartridge could also cause issues, but it typically leads to different symptoms such as fading or blotching, not streaks. The duplex unit and pickup rollers are less likely to be the cause of streaks specifically.
