3. Replace and tighten the screws and perform the 1 mil test again. Even after
this procedure is done it's possible that the disks may still fail the 1 mil test.
In this case you need to adjust the left and right side disks of the same
spindle so that they have equal (error) space.
4. To adjust the right side disks loosen the two screws securing the spindle
select motor to it's motor housing bracket. Twist the motor back and forth
to close the gap between the spindle disks on the right side of the rollers.
If the spindle disks still don't touch then make the space between the left
and right disks on the same roller equal. By doing this you can get the
disks to touch by adjusting the sensors.
The A/B selector sensors should be adjusted so that when the mechanisms
leaves one sensor the flag moves directly towards the other sensor. It should not
move in the opposite direction first and then move towards the other sensor. If it
does the sensors need adjustment.
To adjust the sensors:
1. First adjust spindle "A" sensor. To adjust loosen the two larger 5/16th
screws below the flags. (See Figure 5-5).
Move the assembly until the spindle "A" adjustment works correctly. When
this adjustment is completed spindle "B" sensor may not be detected
because you have move the flag assembly.
2. Adjust spindle "B" by loosening the two small 3/16th screws (see figure 5-
5) and move the flag. Adjust the flag so the flag assembly moves directly to
spindle "B" without moving to spindle "A" first. Moving the flag should not
change the spindle A adjustment.
