5-1. Replacing the Transport Belt
(1) Loosen the transport belt tension adjustment pulley.
Figure 5-1-1
(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%.
To carry out the adjustment, use a pencil or similar tool to put two marks on the belt, which are
200 mm apart from each other.
Move the transport pulley to exert tension so that the distance increases to 201 mm.
Take care with the CENTER buffer so that the transport rails FC and RC do not lift as a result of
the increased belt tension.
