■ Laser scanner motor control
Purpose To rotate the scanner mirror by the specified speed.
Execution timing At power-ON, per printing
Execution time Approx. 3s (at power-ON), approx. 1s (at printing)
Operation 1) The motor speed control area on the DC controller PCB forcibly rotates
the motor.
2) The DC controller detects the speed detection signal (FG, BD) and
compares it with the reference signal generated at the reference signal
generation area, and then controls the acceleration signal (ACC) and
deceleration signal (DEC) to keep the specified speed.

DC controller
MEMO :
To reduce the time for scanner motor speed control, this machine switches the speed
detection point depending on the printer status.
FG signal are the detection signals for roughly adjust the motor speed and used at the
power ON.
BD signal are the detection signals for finely adjust the motor speed and used at the
printing.
