Patent number: 10081198Abstract: 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.Type: GrantFiled: March 1, 2018Date of Patent: September 25, 2018Assignee: Ricoh Company, Ltd.Inventors: Stuart Boland, Scott R.

Patent number: 10060675Abstract: 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.Type: GrantFiled: February 13, 2017Date of Patent: August 28, 2018Assignee: Ricoh Company, Ltd.Inventors: Stuart J.

Patent number: 9352588Abstract: 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.Type: GrantFiled: April 2, 2015Date of Patent: May 31, 2016Assignee: Ricoh Company, Ltd.Inventors: Stuart J.

Patent number: 9156278Abstract: Systems and methods for improving the quality analysis of printheads that apply transparent or hard-to-detect fluids to a media. The system includes a printhead operable to apply a clear fluid to a print media. The system also includes a controller operable to enter a diagnostic mode for quality analysis of the printhead. The controller initiates a supply of diagnostic fluid to the printhead that includes a colorant. The controller then directs the printhead to apply the diagnostic fluid to the print media. Because the diagnostic fluid includes a colorant, the output of the printhead will be more visible on the media.Type: GrantFiled: June 18, 2013Date of Patent: October 13, 2015Assignee: Ricoh Company, Ltd.Inventors: Stuart J.
