Explanation
Correct answer: B) Drum.
Vertical streaks on the output of a laser printer are commonly caused by a problem with the drum (also known as the imaging drum). The drum is responsible for transferring toner onto the paper, and if it becomes damaged or dirty, it can result in streaks or lines on the printed pages.
Here’s why the other options are less likely:
-
A. Roller: While a roller issue could cause paper feeding or smearing problems, it typically does not cause vertical streaks in the print output.
-
C. Transfer belt: The transfer belt helps move the paper and apply toner in color laser printers, but streaks are more commonly associated with a problem in the drum.
-
D. Ribbon: A ribbon is used in dot-matrix printers, not laser printers, so it is not relevant in this case.
