Abstract
The invention achieves efficient use of generation circuits of drive signals COM. The invention provides a liquid ejection method that includes: causing a certain drive signal generation unit to generate a first drive signal and a second drive signal; causing another drive signal generation unit to generate a first drive signal and a second drive signal; supplying the first drive signal generated by the certain drive signal generation unit and the second drive signal generated by the other drive signal generation unit to a certain head unit, the certain head unit being one of a plurality of head units arranged in an intersecting direction that intersects a transport direction of a medium; and ejecting liquid from the certain head unit in accordance with the first drive signal and the second drive signal.
Claims11
A liquid ejection method comprising:
- causing a certain drive signal generation unit to generate a first drive signal and a second drive signal;
- causing another drive signal generation unit to generate a first drive signal and a second drive signal;
- supplying the first drive signal generated by the certain drive signal generation unit and the second drive signal generated by the other drive signal generation unit to a certain head unit, the certain head unit being one of a plurality of head units arranged in an intersecting direction that intersects a transport direction of a medium;
- and
- ejecting liquid from the certain head unit in accordance with the first drive signal and the second drive signal.
A liquid ejection apparatus comprising:
- a transport mechanism that transports a medium in a transport direction;
