How to adjust the tension of the short belt (two belts)
1. Loosen the tension-adjuster-holding bolt.
Loosen the bolt for the section to be adjusted. Do not loosen the two bolts at the same time.
2. With 18.5 +/- 1.5N-pressure applied to one belt with tension gauge, rotate the θ-axis motor five
turns manually, and tighten the tension-adjuster-holding bolt.
With 10-N tension applied to the belt, fix the tension adjuster.
However, to release the excessive tension applied, rotate the θ-axis motor approximately five turns.
3. Repeat the procedures for the other belt.

1. Mount the nozzle holder (B) onto the holder (A).
2. Fit the nozzles (C) onto the nozzle holder (B).
3. Loosen the holder (A)-holding setscrews.
Loosen the two setscrews on each position of A so that the nozzle can be rotated.
4. Adjust the nozzles (Cs: 1 to 6 and 7 to 12) with the jig, and tighten the holding setscrews.
Adjust 1 to 6 first, and then adjust 7 to 12 with 1 to 6 kept adjusted.
Adjust the direction of Cs with the jig.
5. Once 1 to 6 and 7 to 12 have been adjusted, check the jig can be set correctly.
* If adjustment fails, the jig cannot be set.
