4. Using pliers or a flat-head screwdriver, compress the plastic retaining clips holding both
switches in the frame and carefully remove the switches.
5. Using needle-nose pliers, gently compress the plastic retaining clips holding the low-voltage
cable in the frame and remove the connector plug from the frame.
6. Using a Phillips screw driver, remove the screw holding the plastic cover entry shield in place.
Remove the power entry shield.
7. Using needle-nose pliers, remove the two wires at the top of the power entry module —
gently! Grip the plastic connectors and pull away from the power entry module. Be aware that
the green (or green/yellow) ground wire is still attached at the bottom of the module.
8. Compress the top and bottom plastic retaining clips holding the power entry module in place
and remove the module.
NOTE: Use extreme caution, as the clips are breakable. Use a machinists scribe
to compress the retaining clip on the bottom of the module.
9. Using a Phillips screwdriver, remove the screw securing the green and yellow ground wire
running from the power entry module to the electrical housing. Note that there is a star
washer under the screw clip on the wire. This must be in the same position when the ground
wire is reattached.
10. Remove the two screws which attach the electrical housing to the right upper frame.
11. To remove the left upper frame, first remove the upper drive roll motor (see page C–21 for
removal of the upper drive motor and cover and release of the upper drive shaft), then the
electrical cord, and then the spring assembly.
a. To remove the connector from the electrical cord, use an AMP
t
Pin Pusher 458994.2 or
equivalent. Push the two pins through and remove the connector plug. Using a strain
relief plier, release the strain relief securing the upper drive roll electrical cord to the left
upper frame and pull the cord through. Be sure to disconnect the ground wire and retain
the star washer for reassembly. (See Figure C–20)
b. Remove the two screws which hold the spring assembly in place. Complete the removal
of the spring assembly by releasing the tray support cable from the front of the paper tray.
WARNING: The cable is spring loaded and may cause injury.
