To check flatness of the support table, attach a lever dial to the head's OCC camera bracket and
measure flatness near the center of each area circled in the figure below. Adjust the height of the
table so that the difference in flatness at the three positions is within 0.02 mm.

2) Select [Manual Control] → [Transport Control] to set the support table to a position of −27mm.
3) Based on the lowest point of three measured points, turn the adjustment screw in the down
direction (screw tightening direction) to make the adjustment so that the difference among
three measured points is 0.02mm or less.
∗ If all of three screws (screws around the adjustment screws) fixing the ball screw are loosened,
the table may be lowered. To prevent such trouble, always tighten the screws temporarily
after the adjustment with the adjustment screws has been completed.
∗ After the adjustment has been completed, make sure that the center of the rail guide shaft is
aligned with that of the side beam.
