2.6.4 Control of Printing Pulse Width
Superior print quality can be maintained by controlling the print pulse width by the print pulse width
control circuit. This is an oscillating circuit in which the frequency varies depending upon the voltage
and ambient temperature, and provides a specified pulse width by counting a certain number of pulses
with the CPU.
The leading edge of the pulse is synchronized with the timing signal. Control the leading edge of the
pulse by the pulse width control circuit to obtain the rated applied energy.

• Avoid continuous energizing.
• When driving the same dot successively, reduce the applied energy to 80% of the rated applied
energy and slow down the rise of the head driving signal.
