(1) Disconnect the carriage motor harness, registration sensor harness, ink empty sensor harness,
head flat cables, and paper feed motor harness from the main PCB if you have not removed
the main PCB.
Remove those harnesses from the cable guides provided on the lower cover.
(2) Remove screw "x" from the lower end of FG plate R (see the next page) if you have not
removed it on page 4-40.
(3) Remove screws "y" and "z" from the upper ends of FG plates R and L, respectively, then
remove those plates. Removing the FG plate L releases the head flat cables.

NOTE:
If vibration absorbers (black rubber bushings) are left in the lower cover, pull them
out.
