摘要： A technique includes coupling outlets of a first ink supply and a second ink supply together to provide ink to a printhead of a printer; and pressurizing the first ink supply and the second ink supply with air so that an air pressure of the first ink supply has a different air pressure than an air pressure of the second ink supply. The technique includes monitoring an ink-to-air differential pressure of the first ink supply or the second ink supply; and detecting an ink state for the printer based on the monitored ink-to-air differential pressure.

摘要： A print module includes a printhead die, an input regulator to regulate input fluid pressure to the die, and an output regulator to regulate output fluid pressure from the die. A method includes receiving fluid at an input regulator to a print module, creating a fluid pressure differential within the print module between the input regulator and an output regulator, flowing fluid from the input regulator through a printhead die and to an output regulator using the pressure differential, and drawing fluid from the output regulator.

摘要： A fluid injection module may include a fluid ejection die, a die carrier, a bypass fluid passage in at least one pressure regulator. The fluid ejection die may include nozzle orifices on a front face of the die, first and second fluid passages extending through the die and a microchannel extending from the first fluid passage to the second fluid passage proximate the nozzle orifices to circulate fluid from the first fluid passage to the second fluid passage. Third and fourth fluid passages may extend through the die carrier. The bypass fluid passage may extend from the third fluid passage to the fourth fluid passage while being connected to the first fluid passage and the second fluid passage. The at least one pressure regulator is to induce pressure differential driven fluid flow across the microchannel and across the bypass fluid passage.

摘要： In one example, a processor readable medium has instructions thereon that when executed cause a printer to: introduce an unsaturated printing fluid into a channel through which fluid may pass to a printhead; dispense unsaturated printing fluid with the printhead to remove air from the channel; and then introduce regular printing fluid into the channel; and dispense printing fluid with the printhead until regular printing fluid is dispensed from the printhead.

摘要： A print module may include a printhead die. The printhead die may include a chamber layer having ink chambers and micro-channels formed in the chamber layer. The print module may further include a die carrier including manifold passages through which ink flows to and from the printhead die and dual pressure regulators to flow fluid through the micro-channels of the printhead die.
