LD Safety Switch
A relay on the PSU ensures technician and user safety. It also prevents the laser beam from turning on during servicing. This relay turns off when the front cover, upper left cover, or right door is opened. At this time it cuts the power (+5V) supplied to the LD board for each color through the BICU.
Two safety switches are turned on or off by the front door or right door, and this opens the relay.
LD Driver: Precise Pulse Modulation ASIC on C-MOS technology
LDB: LD Drive Board (included in the LD Unit)
