CHAPTER 1
PRECAUTIONS
Read through this manual to design and operate the printer properly.
Pay special attention to the precautions noted in each section.
1.1SAFETY PRECAUTIONS
Follow these precautions when designing a product using the printer, and include any necessary precautions and warning labels to ensure the safe operation of your product by users.
zPreventing the thermal head from overheating
When electricity is continuously supplied to the thermal head heat element by a CPU or other malfunction, the thermal head may overheat, causing smoke and fire.
Follow the method described in Section 3.6.7 to monitor the temperature of the thermal head to prevent overheating.
Turn the printer off immediately if any abnormal conditions occur.
zPreventing the user from touching the thermal head and motor
Warn the user not to touch the thermal head, its periphery or motor as they are hot during and immediately after printing. Failure to follow this instruction may lead to personal injury including burns.
Also, allow cooling by designing clearance between the head, motor and the outer case.
zPrecautions for sharp edges of the printer body
Design the outer case so that the user cannot touch sharp edges of the printer body or the cutting surface of metal parts. Or, provide warnings concerning this matter.
