B-3. CHECK OF THE PHOTODIODES
7 ;
B-4 CHECK OF LASER SUPPLY
The laser, the lasersupply plus the monitor diode form a feedback system.
A
defect
in
the
lasersupply
may
result
in
the
destruction
of
the
laser.
If,
in
that
case,
the
laser
is
replaced,
(=
complete
C.D.M.-unit)
the
new
laser
will
also
become
defective.
However,
it
is
impossible
to
check
and
repair
a
feedback
system
if
a
link
is
missing.
For
this
reason
the
laser
supply
can
be
checked
with
the
replacement
circuit
for
laser
assembly.
