LD Drive Board (PCB14) (PCB15)

The LD Unit is provided with two LD Drive Board. The beam system is a 1 beam type for IM C2000/C2500/C3000/C3500, and 4 beam type for IM C4500/C5500/C6000.

The LD Drive Board comprises an LD (laser diode), PD (photodiode) and LD control unit.

• The LD outputs the laser light to the PCU.
• The PD continuously detects laser light from LD and outputs it to the LD control unit.
• The LD control unit adjusts the light amount of the LD based on the output signal of the PD.

LD control board adjustment is not required in the field.
