3-9 Pulse Width Control of the Head
3-9-1 Head Voltage and the pulse width when temperature changes
Control the width of the pulse depending on the operating voltage to maintain stable
printing quality. 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
℃
.
Refer to below table to check pulses width for temperature.

※ Caution
1) Controlling above the max conditions in upper table causes shorter head life.
Please make sure to control it based on the table provided.
2) The head pulse value by temperature in the above conditions is the standard for
density of paper recommended by BIXOLON.
