Patent number: 11685160Abstract: According to examples, systems and methods for transferring and mixing ink utilizing a tank with a mixing area formed by a funnel portion are described. The mixing area is for mixing new ink and resident ink. In some examples, a new ink supply inlet tube deposits the new ink into the tank from a connected ink supply container. In some examples, a resident ink supply inlet tube deposits the resident ink into the tank from a connected printing device. In some examples, an outlet port situated at tank bottom sends the mixed ink to the printing device.Type: GrantFiled: August 15, 2022Date of Patent: June 27, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: David L. Smith, Nicholas J. Meisner, Robert K. Saathoff

Patent number: 11639826Abstract: In example implementations, a printing device is provided. The printing device includes a printer module, a plurality of dryer modules, and a side exit unit. The printer module is to print on a continuous web of print media. The plurality of dryer modules is located downstream from the printer module. The continuous web of print media is fed in a wrap-around direction from an outermost dryer module to a center dryer module. The side exit unit is coupled to the center dryer module to redirect the continuous web of print media along an outer side of the plurality of dryer modules.Type: GrantFiled: December 22, 2021Date of Patent: May 2, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Ronald R. Anderson, Heather Stokes, Robert K. Saathoff
