4、g completion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1

5、 terminal side. ( if LPS1 signal is low level ). In the Service mode the interlock mechanism will not function. Laser diode oscillation will continue, if pin 41 of TC94A15FG (IC201) on the MAIN Assy is connected to GND, or else the terminals of Q201 are shorted to each other (fault condition). 2. Wh
