■ Basic Sequence
When the control panel power switch is turned on, the laser scanner starts to rotate; when the motor rotationreaches its target
revolution, the machine turns on the laser unit. Thereafter, when the Start key is turned on, themachine generates the image
request signal (PVREQ) on the printer side, and turns on the laser beam withreference to the generated signal.
