It has its own distinctive scent

Every page you print from the central networked laser printer has a single black line that extends from the top of the page to the very bottom. What is the most likely cause of this issue?

A) The corona wire is damaged

B) The printer does not have enough memory to properly render the page

C) The photosensitive drum is damaged

D) The toner is low

E) The printer is tagging each page with its own personal visual marker

The answer: C) The photosensitive drum is damaged

A scratch that extends around the length of the photosensitive drum will result in a thin dark line that extends from the top to the bottom of every page. If the damage was not over the entire drum, you would see intermittent print problems that occur in regular intervals down the page.
