Controlling the Laser Scanner Motor
From when the laser scanner motor starts and the laser scanner motor reaches the number of target rotation to before image formation starts, the machine controlsthe rotation speed by referring to the laser scanner motor rotation speed signal (FG signal).
During image formation, it controls the laser scanner motor rotationspeed based on BD signal.
Laser scanner motor rotation speed is controlled by speed-up signal (ACC signal) and speed-down signal (DEC signal).
