Scanner Frame ASSY
(1)
You can remove the following parts from the top of the scanner frame ASSY without
taking out the ASSY from the main cover:
• Cover glass. Turn the cover glass up towards you.
• Ejection leaf springs. Remove them while slightly pulling up the front edges.
• Document take-in roller ASSY. Unhook the latch of the gear, take it off, and lift up the
ASSY.
• Separation roller ASSY. First unhook the latch of the adjacent gear and take it off,
and then remove the separation roller ASSY in the same way as for the document
take-in roller ASSY.
• Pressure roller ASSY. While pressing down the leaf springs, remove the ASSY.
• Bar lens and LED array.
• Document front sensor actuator.
• Document rear sensor actuator. While pressing down the leaf spring and pulling the
boss "X" provided on the scanner frame ASSY to the front, slightly move the actuator
to the left and lift it up.
• Document sensor PCB. Disconnect the CCD harness and LED array harness from
the document sensor PCB. Take the main-sensor harness out of the three clamps
(see the illustration on the next page) and then disconnect it from the PCB.
