➀
Notes on using thermal paper
Chemicals and oil on thermal paper may cause discoloration and faded printing. Therefore,
pay attention to the following:
a) Use water paste, starch paste, polyvinyl paste, or CMC paste when gluing thermal
paper.
b) Volatile organic solvents such as alcohol, ester, and ketone can cause discoloration.
c) Some adhesive tapes may cause discoloration or faded printing.
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) If thermal paper touches diazo copy paper immediately after copying, the printed
surface may be discolored.
f) Thermal paper must not be stored with the printed surfaces against each other,
because the printing may be transferred between the surfaces.
g) If the surface of thermal paper is scratched with a hard metal object such as a nail,
the paper may become discolored.

Notes on thermal paper storage
•
Since color development begins at 70
°
C {158
°
F}, thermal paper should be protected from
high temperatures, humidity, and light, both before and after printing.
a) Store paper away from high temperatures and humidity.
Do not store thermal paper near a heater or in enclosed places exposed to direct
sunlight.
b) Avoid direct light.
Extended exposure to direct light may cause discoloration or faded printing.
•
When the printer is not used for one week or more, it is recommended not to leave the
thermal paper between the platen and the print head.
3) Others
•
Because this printer uses plated steel, the cutting edges may be subject to rust.
However, this does not affect the printer performance.
