Excitation Setting Adjustment
¡
During the nozzle characteristic test, the condition of ink particle generation
may deteriorate depending on the excitation V-ref., and an abnormality such
as "Ink Drop Charge Too High" may arise and stop the ink. In such a case,
clean the print head and then eject the ink again.
¡
During the nozzle property test, the continuous printing mode becomes
invalid. You can print only once by inputting a signal once.
¡
During the nozzle property test, the product speed matching setting becomes
invalid. Character width may be different from the reality.
CAUTION
In the case where the "Automatic update" is "2: increment":
The excitation V-ref. automatically increases by 1 each
time the printing is performed.
[ex.] Number of printing times : 1st time
→
2nd time
→
3rd time
Excitation V-ref. : [11]

Check the range capable of good printing.
¡
The optimum set value is the center value in the good printing range.
¡
Summarize the printing results as in the following table, and check
excitation voltage capable of printing.
