摘要： Systems and methods are provided for enhanced flushing of printing systems. One embodiment is a printing system that includes an ink flushing controller. The ink flushing controller is able to identify an overlap region wherein nozzles at adjacent printheads of a marking engine overlap along a widthwise direction, to detect primary nozzles that print image data within the overlap region, and to detect overlap nozzles that do not have firing instructions to eject ink within the overlap region. The ink flushing controller is further able to analyze nozzle firing data for each overlap nozzle to determine inactive firing spans for each overlap nozzle, and in response to determining that an inactive firing span for an overlap nozzle exceeds a threshold, to generate a firing instruction directing the overlap nozzle to eject ink.

摘要： A system is disclosed. The system comprises one or more print controllers to generate print interrupt instructions in response to receiving a web splice signal indicating that a web splice on a web print medium has been detected, wherein the print interrupt instructions indicate a first side sheet image and a second side sheet image within a print job to pause prior to stopping printing, wherein the print interrupt instructions comprise gap instructions to open a first printhead gap at the first print engine and to open a second printhead gap at the second print engine, control printing of the first side sheet image on a first side of a web at a first print engine based on the print interrupt instructions, control printing of the second side sheet image to a second side of the web at a second print engine based on the print interrupt instructions, wherein the print interrupt instructions are generated based on a determination of an interrupted first side sheet image to be paused prior to opening the first printhead gap and a determination of an interrupted second side sheet image to be paused prior to opening the second printhead gap.

摘要： Systems and methods for adjustable path length of print media in a dryer of a printing system. In one embodiment, the dryer includes a drum that applies heat to a web of print media. The dryer also includes first rollers positioned in an arc around the drum to define a path of travel of the web along the arc when the web is between an entrance of the dryer and the drum. The dryer further includes second rollers positioned inside the arc from the first rollers to reverse the path of travel of the web inside the arc when the web is between the drum and an exit of the dryer. A first roller and a second roller transport the web around the drum. A location of the first roller and the second roller relative to the arc defines a length of the web inside the dryer.

摘要： Systems and methods for collapsible energy source in a drum dryer of a print system. One system includes a dryer with a thermally conductive drum to dry a colorant applied to a web of print media in contact with the drum. A radiant energy source disposed inside the drum includes segments that transfer heat to a surface of the drum. Each segment is attached to another segment about a hinge that allows the segments to pivot with respect to one another. A movement mechanism applies a force to the radiant energy source toward a center of the drum to cause the segments to pivot to a folded position with respect to one another, and applies a force to the radiant energy source toward the surface of the drum to cause the segments to pivot to expand with respect to a circumferential direction of the drum.
