Caution Symbol
This symbol is placed near the thermal head to indicate that it may be hot.
Never touch the thermal head immediately after the printer has been used.
Let the thermal head cool for a few minutes before touching it.
This symbol is placed near the thermal head to indicate that it is easily damaged.
Observe the precautions for handling electrostatic sensitive devices.
WARNING
1) Do not touch the cutter blade.
• There is a cutter inside the paper outlet slot. Not only should you not put your hand in the
paper outlet slot while printing is in progress, never put your hand into the outlet even
when printing is not in progress.
• The printer cover can be opened when replacing the paper. However, since the cutter
blade is on the inside of the printer cover, be careful not to place your face or hands too
close to the cutter blade.
2) During and immediately after printing, the area around the thermal head is very hot. Do
not touch it, as you could be burned.
CAUTION
1) Do not operate the cover open lever while pressing on the printer cover with your hand.
2) Do not push the cover open lever and open the printer cover when printing is in progress
or when the auto cutter is operating.
3) Do not push out paper while the printer cover is closed.
4) The heating element and the driver IC of the thermal head are easily damaged. Do not
touch them with metal objects, sandpaper, etc.
5) Printing quality may suffer if the thermal head heating element becomes soiled by being
touched with your hands. Do not touch the thermal head heating element.
6) There is a risk of damage to the driver IC of the thermal head from static electricity. Never
directly touch the IC.
7) The printing quality and working life of the thermal head cannot be guaranteed if any paper
other than that recommended is used. In particular, paper containing [Na+, K+, C1-] may
drastically reduce the working life of the thermal head. Please exercise caution.
8) Do not operate the printer if there is moisture on the front surface of the head from con-
densation, etc.
9) A printed piece of thermal paper may become electrically charged. If the printer is placed
vertically or mounted on a wall, the cut piece of paper may stick to the printer, instead of
falling. Beware that this could cause a problem if you use a stacker that stores the pieces
of paper that fall freely.
10) Do not change the paper width during use. The thermal printing head, rubber roller, and
cutter wear differently according to the paper width. This can cause the printing or cutter
movement to malfunction.
11) Do not transport the printer with its cover open and holding it by the cover.
12) Do not forcibly pull on the interface cable, power cable, or cash drawer cable that is con-
nected. To detach a connector, make sure to grasp it at the connector portion, without ap-
plying excessive stress on the connector at the printer.
