Some large format printer with Seiko print heads have this function, JV3 have no this function, I think

in hiden menu i have seen the voltage but how many should i have to increase +1 volt or +0.5

My question is why do you want to do this?
I thought heads were delicate enough without increasing the voltage to them!

Because magenta doesn't spray very well, when i make test magenta line are dentate and i think that, if I increase voltage a little
will spray stronger. Increasing voltage we have make in seiko h74s but in seiko we have increased +3 volt and the head improved spraying.
What do you think should I try? We have and one strajet chinese and the technician increase the voltage of wipe and the contact between head and wipe was stronger.
