※ Safety Precau tio n s
Take precautions with the following items when you design terminals or other products
using the printer mechanism. Include the required precautions in the user’s manual so that
users can use the products such as terminals safely.
a) Precautions to prevent overheating of thermal head
When heating device of the thermal head is activated continuously due to malfunction,
it may cause fire due to overheating of the thermal head. Design the system to prevent
malfunction of the thermal head in case of abnormal conditions.
b) Precautions on temperature increase of the thermal head
The temperature of the thermal head and peripheral devices may increase significantly.
Design the system to prevent burn injuries that could occur when user touches the
thermal head. Attach a warning label so that users can use the device safely. Give
warning to users so that they clean the thermal head only after it has cooled down.
Leave sufficient space between the thermal head and the external case when
designing the external case for faster cooling of the thermal head.
c) Precautions on the increase of motor temperature
The temperature of the stepping motor and peripheral devices may increase significantly
during and right after printing. Design the external case to prevent burn injuries to users
that could be caused when they touch the motor. Attach a warning label so that users
can use the device safely. Leave sufficient space between the motor and external case
when designing the external case for better motor cooling.
d) Precautions for motor drive
User’s hair may get caught between the platen roller and gear if they get too close.
Design the system to prevent printer motor drive when the external case and platen
roller block are open. Design the system to prevent contact between the external case
and the platen roller and gear, and prevent the object jamming. Attach a warning label
so that users can use the device safely.
