A head substrate including a plurality of arrays in each of which a plurality of heaters for ejecting a liquid are disposed, the head substrate comprising:
- one or more first reception units configured to receive communication data including heater selection data on a plurality of arrays, the heater selection data being for selecting the heaters;
- one second reception unit configured to receive communication data including heater selection data on a single array and setting data;
- and
- a second driving unit configured to drive a plurality of sub-heaters so as to reach a predetermined temperature in order to eject the liquid,
- wherein the second reception unit receives setting data for selecting the sub-heaters for the second driving unit.
A head substrate including a plurality of arrays in each of which a plurality of heaters for ejecting a liquid are disposed, the head substrate comprising:
- one or more first reception units configured to receive communication data including heater selection data on a plurality of arrays, the heater selection data being for selecting the heaters;
- one second reception unit configured to receive communication data including heater selection data on a single array and setting data;
- and
- a plurality of detection elements configured to output an analog signal,
- wherein the second reception unit receives setting data for selecting the detection elements.
A head substrate including a plurality of arrays in each of which a plurality of heaters for ejecting a liquid are disposed, the head substrate comprising:
- one or more first reception units configured to receive communication data including heater selection data on a plurality of arrays, the heater selection data being for selecting the heaters;
- and
- one second reception unit configured to receive communication data including heater selection data on a single array and setting data,
- wherein the first and second reception units include a receiver configured to receive a differential signal, an input buffer, and a control circuit configured to analyze the heater selection data and the setting data.
