A.4 Other Notes
1) Printer mechanism handling
• Do not pull the paper out when the cover is closed.
• Because the thermal elements of the print head and driver IC are easy to break, do not touch
them with any metal objects.
• Since the areas around the print head become very hot during and just after printing, do not touch
them.
• Do not use the cover open button except when necessary.
• Do not touch the surface of the print head because dust and dirt can stick to the surface and
damage the elements.
• Thermal paper containing Na
+
, K
+
, and Cl
-
ions can harm the print head thermal elements.
Therefore, be sure to use only the specified paper.
• Label paper cannot be used.
2) Thermal paper handling
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
temperature, humidity, and light, both before and after printing.
a) Store paper away from high temperature 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.
3) Others
• Because this printer uses plated steel, the cutting edges may be subject to rust. However, this
does not affect the printer performance.
