11. [DC685-4] Rotate the Screw with the Adjustment screw as required. (Fig. 5)
The UI indicates the rotation amount and direction of the LSU (ROS) skew adjustment
screw. The number indicates the rotation amount, + meaning to turn the screw clockwise,
and - meaning to turn it counter--clockwise.
For adjustment amount, one click of the adjustment screw (rotate it until it makes a click
sound) is equivalent to 0.05 in number. One rotation is equivalent to 20 clicks.
When the number that cannot be divided by 0.05 is displayed, round it up to 0.05 to reduce
the variation, and rotate it for as many times as the numbers rounded up.
E.g.
When 1.08, 1.09, 1.11, 1.12: make 22 clicks as they are rounded up to 1.10.
When 1.13, 1.14, 1.16, 1.17: make 23 clicks as they are rounded up to 1.15.
(1) Open the Front Cover and remove the collection bottle.
(2) Adjust the adjustment amount read from the UI display with the adjustment screw.
(3) Return the collection bottle and cheat the Interlock.
