An IT support technician is resolving several printer hardware issues across different departments. Match each observed printer symptom to its most likely hardware cause.
- Toner easily smudges or rubs off the paper after printing on a laser printer.Fuser assembly failing to reach or maintain proper operating temperature.
- A thermal receipt printer feeds paper continuously but produces completely blank output.Thermal paper loaded backwards with the heat-sensitive coating facing away from the heating element.
- A laser printer produces pages with a sharp, continuous vertical black streak down the entire page length.Scratched or damaged photosensitive drum (OPC drum) surface.
- An inkjet printer produces printouts with missing color bands and uneven horizontal streaks.Clogged printhead nozzles requiring a cleaning cycle.
Answer
Toner smudging matches the fuser assembly failing to reach operating temperature; blank thermal receipt output matches thermal paper loaded backwards; a continuous vertical black line matches a scratched photosensitive drum; missing color bands on an inkjet printer match clogged printhead nozzles.
Each symptom directly corresponds to the fundamental physical component responsible for that stage of the printing process: fuser heat melts toner, thermal paper coating reacts to heat contact, drum charge integrity dictates vertical line defects, and nozzle cleanliness ensures even ink dispersion.
