1. Position the blue wire [1] as shown in the figure (opposite the Allen
screws) and wind it halfway around the pulley. (The upper half of the
round ball at the end of the wire should be in the hole.)
2. Position the silver wire [2] in the hole on the Allen screw side.
3. Wind the blue wire six times and the silver wire six and a half times, as
seen from the opposite side of the Allen screw. (Do not count the one half
turn on the blue wire from step #1, and make sure to make the extra
wrap on the silver wire.)
4. Position the blue wire [3] in the hole on the Allen screw side and wind it
halfway around the pulley.
5. Position the silver wire [4].
6. Wind the blue wire [3] one and a half times and the silver wire [4] once.
NOTE: a) The blue and silver wires alternate on the pulley (blue uppermost).
b) The wires are not wound on two of the grooves of the pulley as
shown above.
7. Clamp wires onto pulley wires with the fixing jig [A].
8. Set the scanner pulley on the shaft and tighten 2 Allen screws.
NOTE: Maintain 1 mm of clearance as shown in the above figure.
As the thickness of the scale is about 1 mm, put it between the
pulley and the motor and tighten the Allen screws.
