WARNING
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which
may cause birth defects or other reproductive harm (California Health & Safety Code
,
Section 25249 .5).
When servicing or handling circuit boards and other components which contain lead in
solder,
avoid unprotected skin contact wi
th
the solder. Also
,
when soldering do not inhale any smoke or fumes produced.

1.
Laser Interlock Mechanism
The position of the switch (S902) for detecting loading
completion is detected by the system microprocessor,
and the design prevents laser diode oscillation when the
switch (S902) is not in CLMP terminal side (when the
mechanism is not clamped and CLMP signal is high
level.) Thus, the interlock will no longer function if the
switch (S902) is deliberately set to CLMP terminal
side.
(if
CLMP signal is low level).
In the test mode
*
the interlock mechanism will not
function.
Laser diode oscillation will
continue,
if pin 4 of TA2066F
(IC204) on the MOTHER board assy connected to GND,
or pin 19 is connected to high level (ON), or else the
terminals of 0206 are shorted to each other (fault
condition).
