Patent number: 10792944Abstract: A drying apparatus usable with a printing system includes a housing, a first set of radiative heating elements, a second set of radiative heating elements, and an air handling device. The housing includes a front region and a rear region adjacent to the front region. The front region includes an inlet to receive media. The rear region includes an outlet to pass media there through. The first set of radiative heating elements is disposed within the front region to heat the media. The second set of radiative heating elements is disposed within the rear region to heat the media. The air handling device is disposed across from the second set of radiative heating elements to jet air within the rear region to cool the media prior to the media being passed through the outlet.Type: GrantFiled: November 7, 2019Date of Patent: October 6, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Gary Tarver, Jayanta C. Panditaratne, Jason Cassidy Hower, Hua Tan, James Kearns

Patent number: 9676210Abstract: A printing system includes a media transport device to move a medium at a speed ranging from about 15.24 mpm to about 609.6 mpm. The system includes an ink applicator to apply ink on the medium, and a treatment applicator to apply a treatment composition (including liquid vehicle, polyvalent metal salt fixing agent, and latex resin having an acid number less than 20) before or after the ink is applied, to form a printed-on medium. The system further includes a heating system programmed to: i) dry the printed-on medium at a predetermined temperature for a reduced dwell time (from about 1 second to about 40 seconds); and ii) leave residual moisture in the printed-on medium for a predetermined time after the reduced dwell time. The residual moisture is at a level that is higher than an initial moisture content of the medium prior to treatment composition and ink application.Type: GrantFiled: January 20, 2016Date of Patent: June 13, 2017Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ali Emamjomeh, Jayanta C.

Publication number: 20160159077Abstract: A printing system including a print engine, a drying module, and a heating module. The print engine applies printing fluid on media. The drying module dries the printing fluid and provides dried printing fluid. The heating module applies thermal energy to the dried printing fluid and transitions the dried printing fluid to a cured printing fluid that has improved durability versus the dried printing fluid.Type: ApplicationFiled: July 31, 2013Publication date: June 9, 2016Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Jason Cassidy Hower, James Kearns, Gary Tarver, Ali Emamjomeh, Jayanta C.
