Abstract:
A method of connecting a cartridge comprising a fluid composition with a microfluidic delivery system is provided. The method includes the steps of: providing a housing comprising electrical contacts, wherein the electrical contacts of the housing are disposed on a first plane; providing a cartridge comprising a reservoir for containing a fluid composition, a die comprising a nozzle, and electrical contacts that are in electrical communication with the die, wherein the electrical contacts of the cartridge are disposed along a second plane that is parallel with the first plane; and connecting the cartridge with the housing by moving the cartridge in a direction parallel with the second plane toward the housing until the electrical contacts of the cartridge are in electrical communication with the electrical contacts of the housing.
Abstract:
Printing apparatus and methods of producing such a device are disclosed. An example printhead die includes a first resistor (404) to cause fluid to be ejected out of a first nozzle (142; 205; 305) and a second resistor (405) to cause fluid to be ejected out of a second nozzle (142, 205, 305). The example printhead die also includes a first cavitation plate (408) to cover the first resistor (404) and a second cavitation plate (412) to cover the second resistor (405), the first cavitation plate (408) spaced from the second cavitation plate (412).
Abstract:
A printhead with a number of silicon nitride non-volatile memory devices is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium. Each nozzle includes 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. The printhead also includes a memory array with a number of silicon nitride non-volatile memory devices. In one example, the number of silicon nitride non-volatile memory devices are a number of memristors with a silicon nitride switching layer. Each memristor includes a bottom electrode, a silicon nitride switching layer, disposed on a top surface of the bottom electrode, and a top electrode disposed on a top surface of the switching layer.
Abstract:
A print cartridge including a cartridge body, a fluid reservoir disposed within the cartridge body that receives and contains fluid, a fluid ejector chip comprising a plurality of heating elements that eject the fluid from the print cartridge, and a memory device that stores first data related to information regarding the number of times the print cartridge was remanufactured and second data related to information regarding the print yield of the print cartridge for each instance of cartridge remanufacture.
Abstract:
An inkjet printhead (101) includes a packaging label (50) including a first label portion (52) adapted for adhesion to a first surface (181) of the inkjet printhead (101), and a second label portion (54) adapted for adhesion to a second surface (221) of the inkjet printhead (101). The second label portion (54) has a forked configuration including a first outer portion (56), a second outer portion (58) and a central portion (60) disposed between the first and second outer portions (56,58) and adapted for adhesion to a packaging tape (11) adhered to a nozzle plate (21) of the inkjet printhead (101). The adhesion between the second label portion (54) and the second surface (221) of the inkjet printhead (101) is higher than the adhesion between the first label portion (52) and the first surface (181) of the inkjet printhead (101).
Abstract:
Examples of a container assembly are disclosed herein. An example of the container assembly includes a first body to supply printing composition and a second body to store reserve printing composition. The example of the container assembly additionally includes an interconnect having a storage position to fluidically isolate the first body from the second body and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body as needed to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body.
Abstract:
A muzzle cap for a printhead assembly including a main body comprising a side wall, a top wall and a bottom wall, a vent seal disposed within an opening in the top wall, a nozzle plate seal disposed within an opening in the bottom wall, and a nozzle plate seal retainer that holds the nozzle plate seal within the opening in the bottom wall.
