Ricoh MP C3004 - LD Safety Switch

• 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.
LD Safety Switch
To prevent the laser beam from turning on when the front cover or right door is open, the 5V supply to
the LD drive board is interrupted when the interlock switch is open.
