CHAPTER 1

PRECAUTIONS

Read through this manual to design and operate the printer properly.

Pay special attention to the precautions noted in each section.

1.1 SAFETY 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.

Preventing 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 3.6.10 to monitor the temperature of the thermal

head to prevent overheating.

Turn the printer off immediately if any abnormal conditions occur.

Preventing 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.

Preventing the user from touching the rotary drive portion

Design the product so that the motor does not operate when the outer case and platen block

are open. The user could be caught in the motor when the drive gear is exposed.
