CompTIA A+ 220-1101 Practice Question

If a laser printer is leaving streaks on the output, the most likely culprit is the imaging drum. Over time, the photosensitive drum may become worn or damaged, which could cause issues with image quality, such as streaks or spots. Users should check this part first for any signs of wear or debris. Checking the fuser assembly would be relevant if the toner on the prints is not fusing correctly, meaning it could smear when touched. Replacing the toner or refilling it would be required when prints are consistently faint across the whole page or when the toner is low or empty, not for streaks specifically. The pickup rollers are involved in paper handling, pulling the paper from the tray into the printer—if these fail, one might experience paper jams or multiple sheets being pulled at once, not streaks on the output.
