Assembling Notes
• For MFC: When attaching a new LCD back film on the control panel base, face the black
side of the film upwards.
• Before mounting the color LCD unit onto the control panel base, set the latch spring with its
convex section facing upwards, fitting its hole and cutout over the front and rear bosses of the
control panel base, respectively.
• A new color LCD unit is covered with a protection sheet. Before setting it, remove the
protection sheet.
• When mounting the color LCD unit, route the LCD flat cable through the square opening of
the control panel base.
• After setting the color LCD unit back into place, wipe fingerprints or dust off the LCD surface
with a soft cloth.
• After mounting the scanner cover sensor actuator and the ink cartridge cover sensor actuator,
check that each actuator springs back if pressed with a finger.
• When mounting the control panel PCB ASSY, first fit it below the four tabs (see the
illustration on the previous page) on the control panel base and then secure it with three
latches "x."
