8.
Loosen the 2 hexagon socket screws [3] of the
drive pulley on the side so that the drive pulley [1]
can rotate freely against the pulley shaft [2].
9.
Drop the metal ball [5] provided at the intermedi-
ate section of the scanner wire [4] into the drive
pulley installation hole and, with this as a starting
point, wind the wire 6 turns [6] outwards and 5
turns [7] inwards.
Note
• The scanner wires are color-coded. Be sure
to use the one painted black on the front side
with the one with no paint on the rear side.
• For each scanner wire that is wound around
the pulley, be sure to use on the outside the
one at the end of which the metal ball [8] is
provided and on the inside the one at the end
of which the screw thread [9] is provided.
• For each scanner wire, be sure to pull out the
one that is wound on the outside in the paper
feed direction [10] from the upper side of the
drive pulley and the one wound on the inside
in the paper exit direction [11] from the upper
side of the drive pulley.
10.
After completion of the winding of the scanner
wire, be sure to fix it with the tape [12] so that it
does not come off.
11.
Pass the scanner wire [2] provided with the metal
ball [1] through the pulley [4] on the paper exit side
after passing through under the V-mirror unit [3],
and pass further through the pulley [5] inside the
V-mirror unit. And then hook it to the notch [6] of
the frame.
12. Pass the scanner wire provided with the screw
thread through the pulley [7] on the paper feed
side. And then pass it from above through the pul-
ley [8] on the outside of the V-mirror unit and fur-
ther through under the V-mirror unit and, with the
nut [9] and the washer [10], fix it at the tension of
1.3 kg to 1.7 kg.
