9.2 Motor Drive

The LT-286 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 VH 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

VH Voltage Motor Drive Speed

5V 300pps

6V 490pps

7.2V 800pps

Note ) The maximum drive speed depends on the VH voltage.

A printing speed may slightly differ depending on a processing time o r 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.
