A.2 Notes on Printer Installation
• Connect the external power supply to the power supply connector of the printer. Then plug in the
external power supply and turn it on if necessary. Be sure not to connect the external power
supply with the wrong polarity. If it is connected incorrectly, the internal circuit fuse of the printer
may be blown or the external power supply may be damaged.
• The power supply voltage is within the range of 24 V ± 7%. If the power supply voltage drops to
the outside of the range above during printing, the printer stops printing and waits until the voltage
returns to normal and then automatically begins printing again. Therefore, printing speed may
slow, the print pitch may not be correct, and some dots in some characters may not be printed.
• Both high and low voltage errors are shown in table 3.7.3. The blinking patterns are shown in the
table.
• When either a high or low voltage error occurs, turn off the power as soon as possible.
A.3 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.
