3. OPERATION AND TIMING
C. Laser Scanner Motor
The laser scanner motor (M4) is a DC motor, and the motor starts to rotate at a specific speed when the
laser scanner motor drive signal (SMON*) goes '0'. If the rotation speed of the motor is at a specific value, the
laser scanner motor ready signal (SMRDY*) goes '0', indicating to the DC controller that the condition is
normal; if the rotation speed of the motor deviates because of an error, SMRDY* goes '1', displaying error
code 'E110' on the control panel.
