摘要： Examples described herein include a printhead assembly that includes a housing having a printing material reservoir and a print nozzle array disposed in a side of the housing. The print nozzle array is coupled to the printing material reservoir through a first channel. The printhead assembly can also include a pressure equalization element disposed in the side of the housing and coupled to the printing material reservoir through a second channel to allow air to enter the printing material reservoir when a pressure in the printing material reservoir changes.

摘要： In one example in accordance with the present disclosure a printer cartridge is described. The printer cartridge includes at least one backpressure chamber to provide backpressure to a fluid during deposition of the fluid onto a print medium. The printer cartridge also includes multiple fluid chambers in fluid communication with the at least one backpressure chamber. A fluid chamber provides fluid to a portion of a printhead. Adjacent fluid chambers are selectively in fluid communication with one another via valves.

摘要： Printheads and methods of fabricating printheads are disclosed. An example printhead includes a substrate and a printhead die disposed on a surface of the substrate, where a top surface of the printhead die projects a first distance from the surface of the substrate. The example printhead also includes a barrier at least partially surrounding the printhead die. A top surface of the barrier projects a second distance from the surface of the substrate, where the first distance is less than the second distance.

摘要： In one example implementation, a printing device may comprise a number of media skewing rollers to skew a print medium to a predetermined angle with respect to a media feed path and a print engine to print an image on the skewed print medium, the print engine skewing a digital representation of the image based on the predetermined angle such that the image printed is aligned with the print medium. In another example implementation, a printing device may comprise a number of skewing rollers to skew a print medium to a predetermined angle with respect to a media path, a number of pinch rollers to receive the skewed print medium prior to printing, and a print engine skewed to the same predetermined angle as the skewed print medium.

摘要： A print head die may include a substrate, an electrical connector and at least three liquid feed slots. The electrical connector is on a first side of the substrate and extends along the major dimension of the substrate. The electrical connector is connectable directly to an electrical interconnect to connect the print head die to a controller. The at least three liquid feed slots are formed in the substrate and extend along the major dimension of the substrate. Wherein at least one and less than all of the at least three liquid feed slots has an associated temperature sensor connected to the electrical connector.

摘要： A system for drop detection of fluid drops ejected by a printing device includes a drop detector comprising a radiation source and radiation sensor for illuminating a region in which drops are ejected by a print bar and detecting radiation from the radiation source that is reflected by backscattering from the drops to the radiation sensor; and a controller for controlling the drop detector and the print bar, wherein the controller uses a signal output by the drop detector to determine whether nozzles of the print bar are operating properly.

摘要： In one example in accordance with the present disclosure a printhead is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium and an ink delivery system to deliver the amount of fluid from an ink tank to the number of nozzles. The printhead also includes an attachment feature to removably couple a removable printhead cover to the printhead. The printhead further includes a removable printhead cover removably coupled to the printhead at the attachment feature.
