5-10 Pulse Width Control of the Head
5-10-1 Voltage pulse width
Control the width of the pulse depending on the operating voltage to maintain stable
printing quality. The head pulse width can be obtained using the following equation.

5-10-2 Calibration of the pulse width when temperature changes
Detect temperature changes by reading the thermistor resistor values built into the thermal
head. It is advisable to calibrate the pulse width to adjust the energy with the thermal head
for the temperature changes of the thermal head and installation environment temperature.
Stop printing if the detected temperature exceeds 60
℃
. Pulse width per period is
calculated using the following equation.
