Difficulty: EasyPrinter Technologies and Consumables Maintenance

A technician is performing routine maintenance and replacing consumables on a direct thermal printer used at a point-of-sale station. Which of the following items are required for maintaining and operating this specific type of printer? (Select TWO.)

  1. Isopropyl alcohol cleaning swabs to remove residue from the thermal printheadAnswer
  2. Heat-sensitive thermal paper rollsAnswer
  3. C
    Replacement powdered toner cartridges
  4. D
    High-voltage corona wire cleaning brushes

Answer

Isopropyl alcohol cleaning swabs to remove residue from the thermal printhead and heat-sensitive thermal paper rolls.
Direct thermal printing uses a heated printhead that applies heat directly to specialized heat-sensitive paper. Performing maintenance on direct thermal printers involves cleaning the thermal printhead with isopropyl alcohol swabs to remove burnt-on paper residue and installing replacement heat-sensitive thermal paper rolls.

Step-by-Step Solution

1
Identify the core printer technology specified in the scenario
The scenario specifies a direct thermal printer used for receipts.
Direct thermal technology relies on a heated printhead applying direct heat to chemically treated thermal paper without using ribbons, ink, or toner.
2
Determine appropriate maintenance items and consumables for direct thermal printers
The correct items are isopropyl alcohol cleaning swabs for printhead maintenance and heat-sensitive thermal paper rolls as the sole consumable.
Keeping the thermal printhead clean ensures clear print quality, while thermal paper is the required media.
