Ld Safety Switch - Ricoh G165 Service Manual

Laser Exposure

6.3.3 LD SAFETY SWITCH

A safety switch turns off 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.
