Cevap

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.

Adım Adım Çözüm

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.
