DESIGN PRECAUTIONS To maintain the initial level of performance of the printer and to prevent future problems from occurring, observe the following precautions. ◆ If too much energy is applied to the thermal head, it may overheat and become damaged. Always use the printer with the specified amount of energy. ◆ When turning the power on or off, always DISABLE (put in “Low” state) the DST terminals. ◆ To prevent the thermal head from being damaged by static electricity: ◆ Keep the Vp power off when not printing to prevent the thermal head from becoming electrically corroded. ◆ When turning the power on or off, perform the Vp and Vcc simultaneously or in the order of 1) and 2) as follows: At power ON: 1) Vcc (5 V) On → 2) Vp On At power OFF: 1) Vp Off → 2) Vcc (5 V) Off ◆ Always monitor the output of the platen position sensor and paper detector. Incorrect activation of the thermal head may damage and reduce the longevity of the thermal head and the platen. Design the outer case so that the paper detector is not affected by light from outside. Since a reflection type photo interrupter is used in the paper detector, the detector may be affected by light from outside. ◆ Allow for movement of the FPC when designing the outer case because the FPC will shift 2 to 4 mm from the thermal head moving. Also, design the outer case so that it prevents the paper feed out from being caught in the platen. SMP640UKC SPECIFICATION SHEET REVISION A SHEET NO 2 2. GENERAL SPECIFICATIONS 2-1.

Pulse width calibration on temperature change It detects a temperature change by reading a Thermistor Resistance value built in thermal Head. It is recommended to control energy and calibrate the Pulse width into thermal Head based on the installation environmental temperature and a temperature change of thermal Head. When it detects the temperature higher than 60℃, stop the printing process. Pulse per width is calculated the following formula.

Detecting Abnormal Temperatures of the Thermal Head To protect the thermal head and to ensure personal safety, abnormal thermal head temperatures must be detected by both hardware and software as follows: ■ Detecting abnormal temperatures by software Design software that will deactivate the heat elements if the thermal head thermistor(TM) detects a temperature 60°C or higher and reactivate the heat elements when a temperature of 50°C or lower is detected. If the thermal head continues to be activated at a temperature higher than 60°C, the life of the thermal head may be shortened significantly. ■ Detecting abnormal temperatures by hardware If the Control unit malfunctions, the software for detecting abnormal temperatures may not function properly, resulting in overheating of the thermal head. Overheating of the thermal head may cause damage to the thermal head or injury. Always use hardware in conjunction with software for detecting abnormal temperatures to ensure personal safety. (If the Control unit malfunctions, it may be impossible to prevent damage to the thermal head even if a detection of abnormal temperature is detected by hardware.) Using a window comparator circuit or similar detector, design hardware that detects the following abnormal conditions: 1) Overheating of the thermal head (approximately 100°C or higher). 2) Faulty thermistor connection (the thermistor may be open or short-circuited). If (1) and (2) are detected, immediately deactivate the heat elements. Reactivate the heat elements after the temperature of the thermal head has returned to normal.

Note that the maximum period for the ON time is 45 seconds (when the duty cycle is not 100%). SMP640UK SPECIFICATION SHEET REVISION A SHEET NO 15 5. PAPER DETECTOR The printer has a built-in paper detector (reflection type photo interrupter) to detect whether paper is present or not. An external circuit should be designed so that it detects output from the paper detector and does not activate the thermal head and motor when there is no paper. Doing not so may cause damage to the thermal head or platen roller or shorten the life of the head significantly. If the motor is drove when it is out-of paper, a load is put on the reduction gear and the life of the gear may be shortened 5-1.
