4.2.3. Using Thermal Paper
a. Chemicals and oil in the thermal paper may cause discoloration and faded printing. Therefore,
pay attention to the following;
b. When gluing thermal paper, use water paste, starch paste, polyvinyl paste, or CMC paste.
c. Volatile organic solvents such as alcohol, ester, and ketone can cause discoloration.
d. Some adhesive tapes may cause discoloration or faded printing.
e. If thermal paper touches diazo copy paper immediately after copying, the printed surface may be
discolored.
f. If the surface of thermal paper is scratched with a hard metal object such as a nail, the paper may
become discolored.
g. Thermal paper containing Na, K, and Cl ions can harm the print head thermal elements.
Therefore, be sure to use thermal paper that meets the right specifications.
4.2.4. Storing Thermal Paper
a. Since color development begins at 70C (158F), thermal paper should be protected from high
temperature, humidity, and light, both before and after printing.
b. Store paper away from high temperatures and humidity. Do not store thermal paper near a
heater or in enclosed places exposed to direct sunlight.
c. Avoid extended exposure to direct light as it may cause discoloration or fading.
d. If thermal paper touches anything which includes phthalic acid ester plasticizer for a long time, it
can reduce the image formation ability of the paper and can cause the printed image to fade.
Therefore, when storing thermal paper in a card case or sample notebook, be sure to use only
products made from polyethylene, polypropylene, or polyester.
e. Thermal paper must not be stored with the printed surfaces touching against each other because
the printed material may be transferred between the surfaces.
Because this tear bar uses steel, the tear bar may be subject to rust. However, this does not affect
printer performance.
