5-1. Replacing the Transport Belt
1) Loosen the transport belt tension adjustment pulley. (Locations indicated by arrows in the
figure below)
Figure 5-1-1 PWB Transport Block and Transport Belt
2) Replace the belt with the one shown in Table 5-1-1.
3) To provide appropriate belt tension, measure the length of the belt with no tension exerted, and
adjust the position of the transport pulley along the slot so that the belt length increases by
0.5%.
<Adjustment procedure>
Use a pencil or similar tool to put two marks, which are 200mm apart from each other, on the belt.
Move the transport pulley to exert tension so that the distance increases to 201 mm.

5-2. Replacing the Transport Pulley
Two kinds of transport pulleys are available. If the mounting position is changed or the pulley is
mounted incorrectly, this may cause incorrect pulley rotation or incorrect alignment of the transport
belt, resulting in wear on the belt.
Always refer to relevant mounting procedure when mounting the transport pulley.
