摘要： Systems and methods for adjustable interlacing of drying rollers in a print system. One system is an apparatus that includes first rollers that conduct heat from a heat source, and dry a web of print media as the web travels over a front side of the first rollers in a first direction. A last roller of the first rollers turns the web in a second direction. The apparatus also includes second rollers disposed a distance above the first rollers and that transport the web in the second direction. The apparatus further includes a movement mechanism that reduces the distance between the second rollers and the first rollers to cause the second rollers to occupy spaces between the first rollers so that the web traveling in the second direction contacts a back side of the first rollers to further dry the web.

摘要： Embodiments described herein provide rollers that cool a print medium downstream of a dryer while minimizing the temperature differentials across the print medium. In some embodiments, air is directed through the interiors of different rollers in opposing directions based on a pattern to reduce the temperature differential across a width of the print medium. In other embodiments, a controller alternates a direction of the air through the interior of a roller to reduce the temperature differential across the width of the print medium.

摘要： Systems and methods for concentric arrangement of web conditioning modules in a dryer of a printing system. In one embodiment a dryer includes a drum, first rollers positioned in an arc around the drum to define a web path between an entrance of the dryer and the drum, and second rollers positioned along the arc between the first rollers and the drum that reverse the web path between the drum and an exit of the dryer. The dryer further includes first web conditioners positioned along the arc and beyond the first rollers from the drum that direct energy toward a portion of the web path that is between the entrance of the dryer and the drum. The dryer further includes second web conditioners positioned along the arc between the second rollers and the drum that direct energy toward a portion of the web path that wraps around the drum.

摘要： Systems and methods for adjustable S-rollers in a print system. One system is an apparatus that includes a pair of rollers configured to be positioned on opposite sides of a web of continuous-forms print media, and a coupling member that connects the pair of rollers, wherein the coupling member pivots about a common axis between the pair of rollers. The apparatus also includes a drive unit configured to pivot the coupling member and a controller to receive input that describes at least one property of the web, and to direct the drive unit to pivot the coupling member to a position that applies a normal force between the web and at least one of the pair of rollers based on the at least one property of the web.

摘要： System and methods for cleaning printheads and printhead wipers. One embodiment is an apparatus that includes a belt configured to rotate in a loop, and a wiper attached to the belt configured to wipe ink from a printhead. The apparatus also includes a tank configured as a reservoir for a cleaning solution, and a controller configured to drive the belt so that an end of the wiper drags across the printhead when in an upper portion of the loop and submerges in the cleaning solution of the tank when in a lower portion of the loop.

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.
