Abstract: In some examples, a cartridge includes a printhead comprising a fluid feed slot, a fluid chamber formed between a nozzle layer and a passivation layer, the fluid chamber fluidically coupling the fluid feed slot and a nozzle of the nozzle layer, and a printhead-integrated sensor to sense a property of a fluid in the fluid chamber, the sensor including a ground electrode exposed to the fluid chamber through an opening in the passivation layer.

Abstract: An inkjet printing system, fluid ejection system and method thereof are disclosed. The fluid ejection system includes a fluid ejection device and a determination module to determine a supply condition based on the count value output by the converter module. The fluid ejection device includes a fluid supply chamber to store fluid, an ejection chamber including a nozzle and a corresponding ejection member to selectively eject the fluid through the nozzle, a pressure sensor unit having a sensor plate to output a voltage value corresponding to a cross-sectional area of an amount of fluid in the ejection chamber. The fluid ejection system also includes a converter module to output a count value corresponding to the voltage value output by the pressure sensor unit.

Abstract: A printhead includes an address line, data lines, a fire pulse line, and a plurality of primitives, each primitive corresponding to a different data line and including a plurality of activation devices, each activation device corresponding to a different address of a set of addresses. A buffer receives data packets, each data packet including address data representative of an address of the set of addresses and print data for each primitive corresponding to the address. For each data packet, the buffer directs the address data to address logic and places the print data on the respective data line, and the address logic encodes the address represented by the address data onto the address line. For each primitive, the activation device corresponding to the address on the address bus activates a corresponding primitive function based on the corresponding print data when a fire pulse is present on the fire pulse line.

Abstract: In an embodiment, a fluid level sensor includes a sensor plate and a current source. The fluid level sensor also includes an algorithm to bias the current source such that current applied to the sensor plate induces a maximum difference in response voltage between a dry sensor plate condition and a wet sensor plate condition.
