3.6.5 Determination of Activation Pause Time and Activation Pulse Period
Dot lines may be activated in succession to the same thermal dot in order to protect thermal head
elements. Determine the activation period (the time from the preceding activation start to the current
activation start) which conforms to equation (7) to reserve the pause time.
Equation (7):
W > t + 0.5(ms)
W : Activation period of 1-dot line (ms)
3.6.6 Head Activation Pulse Term Coefficient
Make adjustments using the head activation pulse term coefficient (motor drive frequency or equivalent)
as the printing density changes by the printing speed.
According to equations (8), calculate compensation coefficient C of the heat pulse.
Equation (8):
C = 1 -1.15/(1.9+W)
W = 2000 / motor drive frequency
