An IT technician is auditing a facility's printing infrastructure and documenting common hardware defects across various printer types. Match each specific printer symptom on the left with its most likely root cause on the right.
- A thermal transfer label printer feeds media properly but produces completely blank labels.The thermal ribbon is loaded backward with the ink-coated side facing away from the media.
- A monochrome laser printer outputs pages featuring a sharp, continuous black vertical line down the entire length of every page.A physical scratch exists on the photosensitive drum unit or primary charge roller.
- A high-resolution inkjet printer produces photos with white horizontal streaks and missing color bands.One or more printhead micro-nozzles are clogged or dry.
- A network MFD produces copies with a vertical line when using the ADF, but flatbed scans of the same document are clear.Dust, smudges, or white-out residue on the narrow ADF scanner glass strip.
Answer
Thermal transfer blank labels match backward ribbon installation; Laser printer continuous vertical black line matches photosensitive drum surface scratch; Inkjet horizontal missing streaks match clogged printhead nozzles; MFD ADF vertical line vs clear flatbed matches dirty ADF scanner glass strip.
Each print technology exhibits distinct physical breakdown characteristics: thermal transfer ribbons must have their wax/resin side against the media; damaged laser drum surfaces continuously attract toner; blocked inkjet nozzles prevent ink flow along sweep lines; and fixed ADF glass debris creates static image lines as paper moves.
