Do not use this area
because paper feed error
may occur because of
motor torque
1)
Upper table is the value of ts+tm at 65
µ
recommended thermal paper, resistance rank B, RC+rc=0.05, and N=64.
2)
In the shaded area, the drive pulse width is greater than the period of the motor drive. Therefore, use a lower
frequency than that in the shaded area.
