2.1.2 Precautions for Use

• When the two-dimensional barcode or ladder barcode is printed at high speed, it may reduce the
barcode's reading accuracy. In that case, print after switching the print speed to Middle (Quality).
Use Memory Switch or "Set Print Speed" command (GS 's') to change the print speed.
• When the line such as a ruler line is printed, at least 2 dots are needed for configuration.
By configuring with 1 dot only, the printed lines may be hard to see.
• Always use the printer within the shadowed range shown in the graph below for the relationship
between temperature and humidity.
• When handling the printer, be aware of static electricity. When the static electricity is discharged,
this could cause USB communication failure. When this problem occurs, unplug the USB plug that
is connected to the printer and wait a few seconds before connecting it again.
• When the printer is left unused for a long period of time, white powder may appear to the surface
of platen. (This is the powder that an ingredient of thermal paper recrystallized.)
When the powder appears to the platen, wipe the platen with ethanol and use the printer after
ethanol has dried completely.
Also, do not use ethanol on the parts except the platen. When it adheres, wipe it off immediately.
• When printing at high print ratio under a low temperature or high humidity environment, steam
may be generated from thermal paper. This may cause the thermal paper to be contaminated, or
condensation may occur on the printer.
Stop printing when water drops are produced on the thermal head. It causes galvanic corrosion of
the thermal head. If condensation occurs, do not apply current until dewdrops disappear.
• Install the printer on the smooth surface because the rubber feet that adheres to the printer
installation surface are used. When the printer is installed on the uneven surface, it may move
during operation, or its surfaces may peel.
• When the printer is moved from the installation site, hold the printer main body tightly with both
hands, then lift it upward slowly to leave the rubber feet from the installation surface. Lifting it
rapidly or moving it horizontally may peel the entire rubber feet, peel their surfaces, or damage the
outer case.
• Paper feeding may be confused a few dot-lines when printing is started or when printing and paper
feeding are resumed from a pause state. When printing bit images and so on, always feed the
thermal paper for at least 24 steps at the start of printing, and print without interrupting.
