* Note for assembling the copy lamp unit
Move the copy lamp unit to the paper exit side, and fix the copy lamp
unit with the harness guide so that the distance between the copy
lamp harness and the lower frame is about 24±2mm, (25 ~ 30mm)
with the copy lamp harness extended.
After fixing, manually shift the copy lamp unit a few times to check
that it moves smoothly.
If the copy lamp harness is loosely fixed, the copy lamp unit may jump
up when reading, resulting in abnormal reading.
