Abstract
An example provides a fluid ejection apparatus including a fluid feed slot along a length of a print head die of the fluid ejection apparatus to supply a fluid to a plurality of drop ejectors, control circuitry adjacent to at least one side of the fluid feed slot to control ejection of drops of fluid from the plurality of drop ejectors, and a single power supply connector at an end of the print head die to supply power to the control circuitry.
Claims20
A fluid ejection apparatus comprising:
- a fluid feed structure along a length of a print head die of the fluid ejection apparatus to supply a fluid to a plurality of drop ejectors;
- control circuitry adjacent to at least one side of the fluid feed structure to control ejection of drops of fluid from the plurality of drop ejectors, the control circuitry comprising logic for controlling individual or sets of the drop ejectors;
- a single power supply connector at a first end of the print head die to supply power to the control circuitry;
- and
- a ground connector at a second end, opposite the first end, of the print head die to connect the control circuitry to ground.
A fluid ejection apparatus comprising a printhead die;
- and
- a fluid feed slot to a first plurality of drop ejectors and a second plurality of drop ejectors;
- the printhead die comprising:
- first control circuitry adjacent to at least one side of the first fluid feed slot to control ejection of drops of fluid from the first plurality of drop ejectors, and second control circuitry adjacent to at least one side of the second fluid feed slot to control ejection of drops of fluid from the second plurality of drop ejectors;
- and
- a single power supply connector adjacent to an end of the plurality of fluid feed slots to supply power to the first control circuitry and the second control circuitry, the single power supply connector disposed in a corner of the printhead die.
A fluid ejection apparatus comprising:
- a fluid feed structure along a length of a print head die of the fluid ejection apparatus to supply a fluid to a plurality of drop ejectors;
- control circuitry adjacent to at least one side of the fluid feed structure to control ejection of drops of fluid from the plurality of drop ejectors, the control circuitry comprising logic for controlling individual or sets of the drop ejectors;
- a single power supply connector at a first end of the print head die to supply power to the control circuitry;
- and
- a ground connector at both the first end and a second end, opposite the first end, of the print head die to connect the control circuitry to ground.
