To adjust the Micro-adjustment:
The micro-adjustment setting regulates the fluid volume for the dot or line. The higher up the setting, the
more fluid is dispensed.
NOTE The preload screw must be adjusted before performing this procedure. Refer to the “To
adjust the Preload:” procedure earlier in this section.
1. Using a 0.05-inch hex key, loosen the setscrews on the preload screw.
2. Rotate the inner micro-adjustment column so the numbered markings face the solenoid valve.
3. Using the 0.05-inch hex key, tighten the preload set screws, locking the preload screw in place.
4. Using your fingers, loosen the micro-adjustment lock nut by turning it counterclockwise.
5. Turn the outer micro-adjustment collar down and clockwise until it stops.
CAUTION! Do not continue to turn the outer micro-adjustment collar once it stops, or you may
damage the DispenseJet.
6. Use a 1.5-mm hex key to loosen the micro-adjustment collar set screw.
7. Raise and turn the outer micro-adjustment collar clockwise so that the vertical zero (
0) marking
aligns with the vertical centerline on the inner micro-adjustment column.
NOTE The bottom of the outer micro-adjustment collar should align with the horizontal zero
(
0) marking on the inner micro-adjustment column.
8. Using the 1.5-mm hex key, tighten the micro-adjustment collar set screw.
9. Rotate the outer micro-adjustment collar counterclockwise to set the micro-adjustment to the
desired parameter.
NOTE Every ten marks on the outer micro-adjustment collar equal 0.10-mm. For example, a
movement of five marks equals 0.05-mm relative to your starting position. Only the
increment marks on the outer micro-adjustment collar are relevant for adjustment.
10. Finger-tighten the micro-adjustment lock nut.
