9.2 Motor Drive
The MLT-288 uses a 4-phase bipolar stepping motor. It feeds the 1 dot line worth of paper in
two steps by 2-to-2 phase excitation.
9.2.1 Motor Drive Features
1) Drive at an optimum drive speed by the VP voltage.
2) Prevents heat generation of the motor by PWM control to restrain current consumption.
3) Provides acceleration control at the time of start.
9.2.2 Maximum Motor Drive Speeds at Major Voltage
Caution:
The maximum drive speed depends on the VH voltage.
A printing speed may slightly differ depending on a processing time or voltage
detection accuracy. During the course of printing, a motor drive speed may be slower
than the maximum drive speed, depending on what is printed or the head divided drive
system.
