Abstract: A method of operating a printer includes identifying a region of a print medium located between marks formed by a first plurality of inkjets in the printer and an edge of the print medium. The printer activates a second plurality of inkjets to print ink drops into the region during a printing operation. The method enables full-bleed or near full-bleed printing for different media sizes.

Abstract: A method of operating a printer to detect errors in an optical sensor includes forming a printed line across a first side of a print medium and generating first image data corresponding to the printed line with the optical sensor. The optical sensor generates second image data of the second side of the print medium as the print medium passes the optical sensor a second time. A detect in the optical sensor is identified with reference to a difference between process direction alignments of the line in the first image data and the second image data.

Abstract: An inkjet printer is configured with capping stations for storing printheads in the printer during periods of printer inactivity so the viscosity of the ink in the nozzles of the inkjets of the printheads does not increase significantly. Each capping station has a printhead receptacle that encloses a volume, a planar member configured to move between a first position at which the planar member is located within the printhead receptacle and a second position at which the planar member is external of the printhead receptacle, a first actuator operatively connected to the planar member, the first actuator being configured to move the planar member from the first position to the second position, and a controller configured to operate the first actuator to move the planar member from the first position to the second position to mate the planar member with a face of a printhead.

Abstract: A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. A heated evaporator is connected to the cap and is adapted to evaporate an ink-compatible liquid to form a water and/or solvent vapor and supply the water and/or solvent vapor to the sealed space to protect the liquid ink in the nozzles. An insulator thermally insulates the heated evaporator from the printhead. This prevents the ink in the nozzles from drying and prevents the nozzles from clogging.

Abstract: Ink stabilizing material is applied to rotatable panels within a cap of an inkjet cartridge resting structure. The rotatable panels then rotate to contact an inkjet printhead when the printhead contacts the cap. Continuous periodic flushing of the printhead is performed while the rotatable panels are contacting the printhead by periodically and repeatedly alternating between ejecting a mixture of the ink stabilizing material and ink from the nozzles, and drawing the mixture of the ink stabilizing material and the ink back into the nozzles.

Abstract: A jet recovery print process is performed each time before printing a print job, when an inactivity period of non-printing has been exceeded, or during a long print job, where the jets might clog with debris. The jet recovery print process ejects the ink from the inkjets by printing (using the inkjets) a sacrificial page in a jet recovery pattern, while operating the actuators in the inkjets at their maximum voltage rating. The jet recovery pattern is designed to purge all the ink from all the inkjets. Thus, in the jet recovery print process, the controller operates the actuators at their maximum voltage rating so as to provide a higher driving force for the ink to be ejected from the inkjets and thereby make the purge process more effective.

Abstract: A print strategy periodically inserts sacrificial print media, such as a small number of sacrificial sheets of paper into a print job to exercise underused print head jets and prevent nozzle dry-up and/or degraded jetting integrity. This can be implemented with sacrificial sheets out of a tray used by a current print job or from another paper tray housing, for example, the widest stock currently installed in the image forming device. Jets that need to be exercised can be determined by using Feed-Forward image content from the Image Path, and those jets are exercised to print ink on the sacrificial sheet(s). The sacrificial sheet may be diverted to a bypass tray as scrap. Without the need for a purge cycle, or a cycle-down, the image forming device can continue seamlessly to the next print job without performance loss from using the previously under-used print head jets.

Abstract translation: 打印策略定期将牺牲打印介质（例如少量牺牲纸）插入打印作业中以锻炼未使用的打印头喷射并防止喷嘴干燥和/或降低喷射完整性。 这可以用当前打印作业使用的托盘中的牺牲片或来自另一个纸盘外壳（例如当前安装在图像形成装置中的最宽的货物）来实现。 可以通过使用来自图像路径的前馈图像内容来确定需要执行的喷气机，并且执行那些喷射以在牺牲片上打印墨水。 牺牲片可以作为废料转移到旁路托盘。 不需要清洗循环或循环下降，图像形成装置可以无缝地继续下一个打印作业，而不会使用先前使用不及的打印头喷射而造成性能损失。

Abstract: In an inkjet printer, a first printhead forms a first mark on a print medium using a high-contrast ink. A second printhead forms a second mark on the first mark using a low-contrast ink. The printer generates image data of the low-contrast ink mark and the high-contrast ink, and a controller in the printer identifies a cross-process direction offset between the first printhead and the second printhead with reference to a distance between the center of the first mark and the second mark in the image data.

Abstract: A method for printing on a continuous print medium having a plurality of pages includes identifying a location of a feature in image data that are generated from a portion of a first page in the print medium. The method includes modifying a time of operation of a marking unit to form an image on each page in the plurality of pages at a predetermined distance from the edge of each page with reference to the location of the identified feature in the image data. In one configuration, the method enables precise placement of printed images over preprinted forms.
