Ld Safety Switch - Ricoh G190 Service Manual

Laser Exposure

6.4.4 LD SAFETY SWITCH

A safety switch turns off when the front cover or the right door is opened. As a result, the
relay on the PSU cuts off the power supply (+5V) to the four LD boards. (The electric
circuits go through the EGB and IOB.)
The LD safety switch system stops the laser beam when the cover is open.
