LD Safety Switch
A safety switch stops the machine operation when the front cover or the top cover is opened. As a
result, the relay on the PSU cuts off the power supply (+5V) to the two LD boards. (The circuits go
through the EGB.) This system prevents unexpected laser emission, and ensures user safety and
technician safety.
Synchronizing Detector
The machine has one synchronizing detector board. The board detects four colors. The synchronizing
detector board detects the start of the main scan.
