2b. Pull the motor toward yourself to reduce belt tension.
3. Remove the shuttle
3a. Rotate the belt until the shuttle is accessible and unscrew the two
SHCSs (socket-head cap screws) on the inboard side of the car-
riage clamp (2 mm Hex Key).
4. [Tape Output only] Remove the belt cover.
4a. Unscrew three SHCSs attaching the Tape Out belt cover to the
Option Bay (1/8 in. Hex Key). See Figure 4-33.

4b. Viewing the
belt cover
from the
Taping Sys-
tem Opera-
tor’s view, if
you see two
screws on
the left side
of the cover
skip the next
step.
If you see
two screws
on the right

4c. (Some assemblies only) Unscrew two SHCSs mounting the Tape
Out PNP head Assembly to the Option Bay for access to more
cover screws (3/16 inch Hex Key). See Figure 4-34. Without dam-

6c. Connect the belt ends to the shuttle clamp as shown in Figure
4-36. Ensure that the teeth on the shuttle clamp are engaged with
the holes on the belt. If the belt is too long, cut off excess length.
Re-attach the shuttle clamp to the shuttle.
