Reassembling Notes
• When setting the document tray on the scanner unit, pass the bound harnesses (ADF motor
harness, document sensor harness, document tray open sensor harness, and grounding wire)
through the front section of the opening provided in the left rear corner of the document tray,
with its bound section facing up (see the illustration given on page 4-25).
Move those bound harnesses to the rear section of the opening. Route the bound section
through the cable guide so that the cable binder comes into contact with the cable guide as
illustrated on page 4-25. Refer to Subsection 4.1.26 "Harness routing A."
• When putting the scanner unit on the scanner mount, take special care not to bend, wrinkle, or
scratch the CCD flat cable or not to break the boss of the main cover by the bottom of the
scanner unit. (See the illustration given on page 4-24.)
• Connect the document sensor harness, document tray open sensor harness, ADF motor harness,
and panel harness to the relay PCB, and secure the two grounding wires to the main cover as
shown in Subsection 4.1.26, "Harness routing B."
