1. As the BU table moves up and down, the transport rail CF and CR move up and down smoothly.
Check procedure:
Check to see if the transport rails follow the up-and-down movement of the transport rails.
Push up the rail guide shaft with a finger to determine if the transport rails lightly move up.
PWB guide set screws
If the PWB guide interferes with the rails, loosen the screws shown
below and adjust.
Press with a finger.
1. To clamp the PWB smoothly in the vertical direction
1. Interference with the PWB guide prevents the transport rail from moving up.
The right and left shaft support assemblies do to run parallel with each other, causing the rails to bind.
A defective shaft support bearing causes the rails to bind.

Directly concerned with the settling time (damping characteristics) at the placement and pickup positions, it greatly affects the
placement accuracy.
1. Degraded placement accuracy
2. Pickup failure resulting in a standing chip and laser error
3. Hunting at stopping
4. Abnormal oscillation during operation
5. Degraded stopping accuracy
