3.9.3 Scanner Cover (Scanner Unit) and Scanner Cover Support
The scanner cover should be removed together with the ADF & document cover ASSY whose
removal procedure is given in Section 3.9.4. The disassembly of the ADF & document cover
ASSY is detailed in Section 3.9.5.
(1) Disconnect the white CIS flat cable (for second side scanning)* from the main PCB and
remove the two flat cores from the cable.
*For duplex scanning models
(2) Disconnect the black CIS flat cable (for first side scanning) from the main PCB and pull it
to the rear through the two flat cores* (single flat core for the simplex scanning models),
and then release it from the cable guides. Unlatch the flat cores and take them out of the
upper cover.
Note
: After disconnecting the flat cable(s), check that each cable is not damaged at its end
or short-circuited. When connecting the flat cable(s), do not insert it at an angle. After
insertion, check again that it is not at an angle.
(3) Release the two CIS flat cables from the cable guides together with the flat cable support.
(4) Release the two grounding wires by removing the screw.
(5) Disconnect the following harnesses from the main PCB.
- ADF motor harness (4-wire)
- CIS motor harness (4-wire)
- Document detection/width & scanning position (first side) sensors harness (7-wire)
- Document scanning position sensor harness (second side) (3-wire)*
- ADF cover switch harness (2-wire)
