■ Reassembling Notes • Make sure that the power supply PCB is completely fitted in the resin PCB supports of the main frame. If it is loosely mounted so that it comes into contact with the bottom plate, a short circuit may occur. • For the FAX-270MC/290MC/520DT/520MC/MFC370MC/390MC: After putting the scanner frame ASSY back onto the main frame, route the harnesses and arrange the cores as follows, referring to the illustration given on the previous page. - Hook the power supply harness core on boss "C." - Check that the cutter HP sensor harness runs through a core, and then hook the core on boss "D." - Push the CIS harness core and the recording head harness core to the left of rib "E" and behind relay "F." - Route all these harnesses under boss "D." If any of these harnesses and cores are out of the specified position, the scanner frame ASSY or ROM cover may not be put back into place. • For the FAX-270MC/290MC/520DT/520MC/MFC370MC/390MC: After connecting these harnesses, check that neither the electrolytic capacitor nor resistors are tilted towards the PE sensor actuator. If tilted, they may interfere with normal operation of the sensor actuator.

Reassembling
Notes
•
Make
sure
that
the
power
supply
PCB
is
completely
fitted
in
the
resin
PCB
supports
of
the
main
frame.
If
it
is
loosely
mounted
so
that
it
comes
into
contact
with
the
bottom
plate,
a
short
circuit
may
occur.
•
For
the
FAX-270MC/290MC/520DT/520MC/MFC370MC/390MC:
After
putting
the
scanner
frame
ASSY
back
onto
the
main
frame,
route
the
harnesses
and
arrange
the
cores
as
follows,
referring
to
the
illustration
given
on
the
previous
page.
-
Hook
the
power
supply
harness
core
on
boss
"C."
-
Check
that
the
cutter
HP
sensor
harness
runs
through
a
core,
and
then
hook
the
core
on
boss
"D."
-
Push
the
CIS
harness
core
and
the
recording
head
harness
core
to
the
left
of
rib
"E"
and
behind
relay
"F."
-
Route
all
these
harnesses
under
boss
"D."
If
any
of
these
harnesses
and
cores
are
out
of
the
specified
position,
the
scanner
frame
ASSY
or
ROM
cover
may
not
be
put
back
into
place.
•
For
the
FAX-270MC/290MC/520DT/520MC/MFC370MC/390MC:
After
connecting
these
harnesses,
check
that
neither
the
electrolytic
capacitor
nor
resistors
are
tilted
towards
the
PE
sensor
actuator.
If
tilted,
they
may
interfere
with
normal
operation
of
the
sensor
actuator.
