Abstract: In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

Abstract: According to an example, an apparatus may include a fluid coverage engine to determine which pixels of an image are to receive print fluid. The apparatus may also include a pixel count engine to compute a count of pixels at which print fluid is to be applied onto a media from the determined pixels of the image that are to receive print fluid, a target temperature engine to determine a target temperature for a dryer based upon the computed count of pixels, and a dryer engine to cause the dryer to become heated to the determined target temperature.

Abstract: Example implementations relate to print medium processing. For example, a non-transitory computer readable medium may store instructions executable by a processing resource to determine an attribute of a print medium and adjust a print processing parameter based on the attribute of the print medium. The non-transitory computer readable medium may further store instructions executable by the processing resource to process, with a page processing mechanism, the print medium based on the print processing parameter.

Abstract: In one example, a processor readable medium having instructions thereon that when executed cause a printer controller to monitor a temperature of a dryer in the printer, continue to apply power to a heating element in the dryer after executing a first print job and before executing a second, next consecutive print job, and turn off the power applied to the heating element if the temperature of the dryer exceeds a threshold temperature while the printer is not printing.

Abstract: A ferro-fluidic inkjet printhead sealing and spitting system is provided for maintaining inkjet printhead health, prior to and after installation in an inkjet printing mechanism. As a ferro-fluidic capping system for sealing printhead nozzles which eject ink having either polar properties or non-polar properties, the system includes a support structure engageable with the printhead, and a magnetic element supported by the support structure. A ferro-fluidic fluid overlays the magnetic element to seal against the printhead nozzles when the support structure is engaged with the printhead. The ferro-fluidic fluid has polar properties when the ink has non polar properties, and non-polar properties when the ink has polar properties. The ferro-fluidic fluid may be used to receive ink spit from the printhead, or when used with an adhesive tape, to protect an inkjet cartridge during shipping. An inkjet printing mechanism having such a ferro-fluidic system, along with associated methods are also provided.

Abstract: An inkjet printhead service station for cleaning an inkjet printing mechanism includes a printhead wiping system having a grooved wiper blade tip for wiping ink residue from the printhead, which is especially useful for cleaning printheads having surface irregularities such as encapsulant beads, which are required to assemble the printhead. The wiper blade is supported by a sled to engage and wipe the printhead in a wiping direction, with the blade having a wiping tip which defines a transverse groove running transverse to the wiping direction. The wiper blade has opposing leading and trailing surfaces between which the groove runs, preferably without intersecting either the leading surface or the trailing surface. An inkjet printing mechanism having such a wiping system, and a method of cleaning an inkjet printhead are also provided.

Abstract: Document characteristics such as print media and selectable print quality variations are used to determine printhead servicing, e.g., service spitting of ink-jet nozzles. If the next sweep contains the next color in the pen or printhead set, and the next sweep would be greater than the number of sweeps since the last firing of that color ink—whether on page or at the service station—and the last sweep did not fire droplets of the color, a decap service spit and nozzle firing tracking reset is triggered. All service calls spit fire all nozzles, so all timer values are reset whenever at a service spit. Reaching or exceeding a fail-safe limit similarly triggers a decap service spit or other known manner service station operations.
