Reassembling Notes
• Take care not to mistake the upper LF roller ASSY (gray) for the lower LF roller ASSY (black).
• When setting the document sensor PCB back into place, do not push it down straight, but first
fit the PCB in the large latch and then fit it in the small latch (see the illustration given on page
IV-20).
• Be sure to route the document sensor harness through the three harness guides so that it will
not interfere with the document rear sensor actuator. (See the illustration given on page IV-20.)
• Reinstall the ADF motor with its connector side facing up. (See the illustration given on page
IV-19.)
• Reinstall the ADF side covers so that the tabs of the ADF side plates become fitted inside the
ribs provided on the ADF side covers. (See the illustration given on page IV-18.)
• When reinstalling the ADF side cover R, be sure to route the document sensor harness, ADF
motor harness, and grounding wire between the boss and the ADF side cover R. (See the
illustration given on page IV-18.)
• When reinstalling the ADF unit, first set the ADF support onto rear pin "x" of the ADF unit, set
the ADF unit back into place, set the other ADF support onto front pin "y," then secure those
ADF supports with two screws "c." (See the illustration given on page IV-17.)
