Faded images from previous jobs appear on each page of output from an office printer. Which of the following should a technician do first to resolve this issue?

The correct answer is D. Clean the corona wire. Ghosting, where faint images from previous print jobs appear on new pages, is commonly caused by a dirty corona wire. Cleaning the corona wire restores proper charge distribution so toner does not remain on the drum between print cycles.
