Explanation
Inkjet printers have physical print heads with tiny nozzles that must be calibrated and aligned to ensure accurate ink placement and print quality.
Common mistakes.
- A. Impact printers use a print head with pins that strike an ink ribbon against paper - there are no spray nozzles to calibrate.
- C. Laser printers use a photosensitive drum, toner, and fuser assembly with no liquid nozzles, so nozzle calibration is not applicable.
- D. Thermal printers produce images by applying heat directly to thermal paper and have no ink nozzles that require calibration.
