(5) Lift up the ACS grounding spring. • Reassembling Notes • Before putting the scanner frame ASSY back onto the main frame, be sure to set the ACS grounding spring as illustrated on the previous page. • Make sure that tabs "A" of the scanner frame ASSY are fitted in cutouts "B" provided in the main frame. (See the illustration on the previous page.) • 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 below. - 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 into position, 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
•
Before
putting
the
scanner
frame
ASSY
back
onto
the
main
frame,
be
sure
to
set
the
ACS
grounding
spring
as
illustrated
on
the
previous
page.
•
Make
sure
that
tabs
"A"
of
the
scanner
frame
ASSY
are
fitted
in
cutouts
"B"
provided
in
the
main
frame.
(See
the
illustration
on
the
previous
page.)
•
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
below.
-
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
into
position,
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.
