Control description
1. The Y/M Laser Driver PCB forcibly emits the Bk laser diode of the C/Bk Laser Driver PCB by setting the Bk laser control
signal to APC mode.
2. The laser beam of the Bk laser has a BD circuit in the scanning light path, and is incident on the BD Circuit.
3. The BD Circuit detects the laser beam and generates a BD signal, and sends it to the Main Controller.
4. The Main Controller synchronizes with this signal, and sends video signals (Y_VDO, M_VDO, C_VDO and Bk_VDO) to the
Y/M and C/Bk Laser Driver PCBs while regarding the reference BD signal as the vertical scanning synchronous signal (BD)
for each line. This enables each Laser Driver PCB to emit a laser beam from a fixed position for each line.
NOTE:
• As the BD signal is the horizontal scanning synchronous signal of the Bk color, the Bk color serves as each color's
reference for horizontal scanning.
• With this machine, the reference in the horizontal scanning direction for Y and M colors is the right edge (right-to-left)
while that for C and Bk colors is the left edge (left-to-right).
