Study Notes
Thermal Printer Operation
- Thermal printers use heat to create images on specially coated white paper.
- No ink or toner is used; heat directly changes the paper's color (black).
- Printers are very quiet.
- Commonly used for receipts.
Thermal Paper Sensitivity
- Thermal paper is highly sensitive to heat.
- Exposure to sunlight or heat sources causes the entire page to darken.
- Clear tape applied to thermal paper lightens the area covered.
- Thermal paper is unsuitable for archiving due to its sensitivity to heat.
Paper Feed Mechanism
- A feed assembly, a long cylinder, holds and moves paper through the printer.
- Gears on the assembly rotate the cylinder, moving the paper.
Heating Element
- A silver heating element creates the printed output.
- The heating element doesn't move—the paper passes over it.
- Different parts of the heating element heat up different parts of the paper.
Thermochromic Paper
- The chemical change causing the color change is termed "thermochromatic" or "thermal" paper.
- When heated, specific areas of the paper change color.
- The printing process is very fast and quiet.
Paper Type Importance
- Thermal paper differs significantly from standard paper.
- Ensure correct paper type when buying/replacing paper in a thermal printer.
- Receipts are a common application of thermal printing technology.
