Liquid ejection apparatus, recording medium, and liquid ejection head

A non-transitory computer readable recording medium storing a program causing a computer included in a liquid ejection apparatus that comprises a driving substrate;

• a liquid ejection head connected to the driving substrate via a cable;
• a converter that converts a signal received via the cable from a serial signal to a parallel signal, and a generator that generates a control signal for driving a predetermined driver,
• to function as:
• a measurer that measures a conversion delay time of the signal at the converter based on a reference signal which is received by the liquid ejection head from the driving substrate and is converted by the converter together with the signal, and
• an adjuster that adjusts a timing at which the control signal is outputted from the generator, based on the conversion delay time measured by the measurer.

A liquid ejection head that is connected to a driving substrate via a cable and causes a plurality of nozzles to eject liquid based on a signal for causing each of the plurality of nozzles to eject liquid, the liquid ejection head comprising:

• a converter that converts a signal received via the cable from a serial signal to a parallel signal,
• a driver that drives an actuator that causes the nozzles to eject liquid when the signal subjected to parallel conversion by the converter is inputted in the driver, and
• wherein the converter outputs a reference signal, which is part of the signal converted by the converter, to the driving substrate where a conversion delay time of the signal at the converter is measured based on the reference signal, and
• wherein the driver is driven by a control signal having a timing adjusted based on the measured conversion delay time.
