1.1 Overview
This chapter describes how to troubleshoot problems. Be sure to see the tables
provided in this chapter to identify the component that caused the problem you face.
And follow the instructions in the table to troubleshoot the component. Also refer to
the Motor Wire-Wound Resistor and Sensor Check Points.

NOTE:As the CR Motor and the APG Motor are DC motors, the resistance between the pins
fluctuates. So checking them if they work properly or not is made only by observing them
visually (if they rotate or not). It is, however, sometimes difficult to judge, so when in
doubt, replace the motor.
