Overview
Basic Sequence
Initial rotation (INTR):After the control panel key is ON, the machine starts the polygon motor and rotates the laser polygon motor until it reaches the number of target rotation while keepingall laser OFF.
Once it reaches the target, the machine enters stand-by mode(FG control).
If pressing the start key before the control panel key is ON*, standby time gets shorter after the polygon motor reaches the target.
Print (PRINT):When copy start key is ON, the machine drives A laser.
After BD PCB detects A laser, the machine performs the APC (laser intensity) control of each laser.
Oncethe BD signal reaches the specified cycle, the machine is ready to print.
Image data is output from the main controller based on the synchronous signal and laser isemitted corresponding to it.
But iR4025 is based on a C laser(The substitute of the A laser) for 2 beam (C, a D laser).
