INSTRUCTED PERSON.
The AEL(accessible emission level) of the laser power output is less then CLASS 1
but the laser component is capable of emitting radiation exceeding the limit for
CLASS 1.
A specially instructed person should servicing operation of the apparatus.

1. Laser Interlock Mechanism
The position of the switch (S1) for detecting loading
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
terminal side. ( if LPS1 signal is low level ).
Bottom Plate
In the test mode
Laser diode oscillation will continue, if pin 33 of CXA1782CQ
(IC101) on the MOTHER BOARD ASSY is connected to
GND, or pin 43 of IC701 (LDON) is connected to low level
(ON), or else the terminals of Q101 are shorted to each
other (fault condition).
