5-10. Replacing the Centering Pin (Optional)

1) Loosen the screws c, d and e of the guide block A and guide block B to detach the centering

pin together with the guide blocks.

2) At this time, also detach the T-PIN sensor (together with its bracket) from the reference side.

Removing the E ring

allows you to pull the centering pin

from the damper block.

Removing the E rings

(two in total, top and bottom) allows you to remove the centering pin

When installing a new centering pin, reassemble the components in the reverse order. The

E-rings must also be replaced with new ones.

After the components have been reassembled, adjust the sensor position in the same manner

as described in 5-10, Replacing the T-PIN Sensor.

5-11. Replacing the Support Table Motor (BU Motor)

1) Remove the support table as described below.

1. Stretch the transport width as much as possible.

2. Remove 12 (∗) pan head screws d from the support table c to detach the table.

∗ For the number of screws, the L-specification uses 12 pcs. while the XL-specification

uses 14 pcs.

Figure 5-11-1 Support Table

2) Loosen the tension support fixing screw f, and move the tension support assembly e in the

arrow direction to loosen the tension of the support table ball screw driving timing belt

3) Loosen the set screws h to take out the support table BU motor assembly g together with the

torque support.

4) Loosen the set screws i to detach the torque support assembly from the shaft of the BU motor

5) Assemble the parts and components in the reverse order of above steps 1) to 3). When

assembling the parts and components, perform the following adjustments.

• Adjust the gap between the torque support and BU motor assembly. (section 5-11-1)

• Adjust the tension of the support table driving timing belt. (section 5-11-2)

• Place the support table surface horizontally. (section 5-11-3)

• Obtain the support table offset. (section 3-11 in MS Parameter)

5-11-1. Adjusting the Gap between Torque Supporter and Support Motor

The gap between the torque supporter and support table motor must be adjusted to 1.1 mm.

5-11-2. Adjusting the Tension of the Support Table Driving Timing Belt

To adjust the tension of the support table driving timing belt, loosen the screw of the tension

supporter assembly and move the assembly in the arrow direction, input the said values to the sonic

belt tension meter (manufactured by UNITTA), measure the tension at the locations shown below,

and then adjust the tension within the required range.

• Values to be input to the sonic belt

5-11-3. Placing the Support Table Surface Horizontally

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 four positions is within 0.02 mm.
