Match each printer symptom on the left with its most likely underlying cause on the right.
- Thermal printer outputs completely blank pages despite feeding paper normally.Paper was loaded upside down or standard non-thermal paper was used.
- Laser printer output smudges and rubs off the page easily.Fuser element is failing to reach the temperature needed to permanently melt toner.
- Impact (dot-matrix) printer produces faint, barely legible characters across the entire page.Fabric ink ribbon is dried out or worn down.
- Inkjet printer output has horizontal lines missing across text and images.Printhead nozzles are clogged and require a cleaning cycle.
Answer
Thermal blank output matches paper loading/type issues; laser toner smudging matches fuser heat failure; impact faint text matches a dried ink ribbon; inkjet horizontal streaking matches clogged printhead nozzles.
Each printer technology relies on unique components and consumables: thermal printing requires correctly oriented heat-sensitive paper, laser printers depend on a working heating fuser to melt toner powder, impact printers require an inked ribbon for pin transfers, and inkjet printers need clear nozzles to spray liquid ink without streaking.
