● Excitation Setting Adjustment 7-30
7.13 Excitation Setting Adjustment
(1) Overview
● Excitation V-ref. are from 0 to 19.
● To maintain good printing quality, it is necessary to input an optimum excitation
V-ref..
● Conduct a nozzle property test, and set a center value in a range capable ofgood
printing as the optimum excitation V-ref..
(ex.) In the case where the good printing is performed when the excitation
V-ref. is 5 to 15 in the nozzle property test, the optimum excitation
V-ref. is 10 at the center.
● An ambient temperature when updating the excitation V-ref. is stored as a reference
temperature. If the difference between the ambient temperature and the reference
ambient temperature exceeds a certain value, a warning "Excitation V-ref. Review"
arises. Update the excitation V-ref. in that case.
