6.11 Excitation V adjustment
(1) Overview
● The Excitation V set value is 0 to 19. The state of the ink drops is different for each setting.
● The optimum Excitation V set value must be input to maintain good print quality.
● Perform nozzle property test printing, and the center value of the range where printing is good is the optimum
Excitation V set value.
(Example) When printing is good at the Excitation V set value 5 to 15 range at nozzle property test, the
optimum Excitation V set value is the center value 10.
● Memorizes the ambient temperature when the Excitation V set value was updated as the reference ambient
temperature.
If the ambient temperature and the reference ambient temperature difference exceeds a certain value during
use, "Check Excitation V set value" warning will be generated. In that case, readjust the Excitation V setting.
(2) Operation
● For Excitation V setting, select the optimum set value from the result of test printing for each set value and
input the selected value from the operation panel. Perform operation in accordance with the following
procedure:
At the Maintenance menu, press Excitation V update (nozzle test) .
