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
!
This printer has no platen position detector. Attach a detector to the outer case to monitor
whether or not the platen block is properly secured. Also, design the product so that the
thermal head is not driven when the platen block is open.
Warn the user not to touch the thermal head or its periphery as they are very hot during and
immediately after printing.
Also, allow cooling by designing clearance between the head and the outer case.
!
Preventing the user from touching the motor
Design the outer case so that the user cannot touch the motor as the motor are very hot
during and immediately after operating.
Also, allow cooling by designing clearance between the motor and the outer case.
Drive the motor within the continuous drive time and pause time described in Section 3.4.3.
!
Preventing the user from touching the rotary drive portion
This printer has no platen position detector. Attach a detector to the outer case to monitor
whether or not the platen block is properly set. Also, design the product so that the motor
does not operate when the platen block is open, to prevent the user from getting caught in the
motor because the drive gear is exposed.
!
Preventing the user from touching the sharp edges of the printer
Design the product so that during handling the user cannot touch the edges of the printer,
particularly the cut surfaces of metal parts because of the risk of injury. Implement a design
that prevents such contact, or provide ample warnings.
