Abstract
In one example in accordance with the present disclosure a flexible printhead is described. The printhead includes a number of printhead die, a printhead die including a number of nozzles to deposit an amount of fluid onto a print medium. The printhead also includes a fluid delivery system to deliver the amount of fluid from a fluid supply to the number of nozzles. The printhead also includes a number of electrical circuits to electronically couple the number of printhead die with a printing device. The printhead also includes a flexible substrate on which the number of printhead die and the number of electrical circuits are mounted.
Claims20
A printhead comprising:
- multiple printhead dies, the printhead dies comprising a number of nozzles to deposit an amount of fluid onto a print medium;
- a fluid delivery system to deliver the amount of fluid from a fluid supply to the number of nozzles;
- a number of electrical circuits to electronically couple the multiple printhead dies with a printing device;
- and
- a flexible substrate on which the multiple printhead dies and the number of electrical circuits are mounted, wherein the flexible substrate is curved to follow a contour of a media transport assembly.
A method for forming a printhead comprising:
- forming a first layer of the printhead, the first layer comprising:
- a printhead die that includes a number of nozzles;
- and
- flexible electronic circuitry to provide electrical signals to the printhead die, the electrical signals to control ejection of fluid from the number of nozzles;
- forming a second layer of the printhead, the second layer comprising a flexible substrate on which the printhead die and the flexible electronic circuitry are to be mounted;
- and
- attaching the first layer of the printhead to the second layer of the printhead to form a flexible printhead.
A printhead comprising:
- a number of nozzles in a printhead die, the number of nozzles to deposit an amount of fluid onto a print medium, each nozzle comprising;
- a firing chamber to hold the amount of fluid;
- an opening to dispense the amount of fluid onto the print medium;
- and
- an ejector to eject the amount of fluid through the opening;
- a number of flexible electrical circuits to electronically couple the printhead die with a printing device;
- and
- a flexible substrate on which the printhead die and the number of flexible electrical circuits are mounted, wherein the flexible substrate is curved to follow a contour of a media transport assembly.
