Reassembling the Rear Scanner Wire
1. Position the center ball [A]
in the middle of the forked
holder.
2. Pass the left end (with the
ball) [B] through the drive
pulley notch, and the right
end (with the ring) [C]
through the drive pulley
hole.
3. Wind the left end
counterclockwise (viewed
from the machine’s front)
five times; wind the right
end clockwise three times.
NOTE: The two red marks [D] meet when you have done this. Stick the wire to
the pulley with tape, so you can handle the assembly easily during
installation.
4. Install the drive pulley on the shaft.
NOTE: Do not secure the pulley on the shaft with the screw yet.
5. Install the wire.
NOTE: The winding of the wire on the three pulleys at the rear of the scanner
should be the same as the winding on the three pulleys at the front,
except that it should appear as a mirror image.
Example: At the front of the machine, the side of the drive pulley with
the three windings should face the front of the machine. At the rear of
the machine, it should face the rear.
6. Perform steps 7 through 13 in the “Reassembling the Front Scanner Wire”
Section.
