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.
