(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.
