Publication number: 20220281244Abstract: A system is disclosed. The system comprises a roller with a spindle to wind and/or unwind a roll of media, a media advancement sensor to measure the advancement of the media, and a controller. The controller is to control the spindle to rotate an angular displacement, and to determine a calculated media advancement based on the angular displacement and a radius of the roll of media. The controller is also to receive from the media advancement sensor a measured media advancement. The controller is further to detect that a displacement difference between the measured media advancement and the determined media advancement exceeds a predetermined threshold. If the displacement difference exceeds the predetermined threshold a slippage condition is detected.Type: ApplicationFiled: September 26, 2019Publication date: September 8, 2022Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Albert Estella Aguerri, David Munoz Navarro, Francisco Guerrero Carvajal

Patent number: 11415934Abstract: Disclosed herein is a device, a printing device and a method of operating a printing device. The device comprises an air flow path extending from an intake to an outlet. The intake is to be mounted in a printing device and comprises a proximal intake segment and a distal intake segment along the air flow path. A proximal air flow path from the proximal intake segment to the outlet is shorter than a distal air flow path from the distal intake segment to the outlet. Each of the proximal and distal intake segments comprises a wall segment with at least one hole. An opening ratio of an area of the at least one hole and an area of the respective wall segment is larger in the distal intake segment than in the proximal intake segment.Type: GrantFiled: July 16, 2019Date of Patent: August 16, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Javier Deocon Mir, Francisco Guerrero Carvajal, Diego Lopez Ubieto

Patent number: 9227436Abstract: A primer, a method, and a non-transitory computer-readable storage medium are described. An example non-transitory computer-readable storage medium stores instructions that, when executed by a processor, cause the processor to instruct a printer to advance a media by a first distance. The instructions, when executed, also cause the processor to instruct the printer to advance the media by a second distance different than the first distance to align the media with a cutter assembly. The instructions, when executed, also cause the processor to adapt an interleave mask based on the second distance. The instructions, when executed, also cause the processor to instruct the cutter assembly to separate a first portion of the media from a second portion of the media while the printer is printing on the media.Type: GrantFiled: December 29, 2011Date of Patent: January 5, 2016Assignee: Hewlett-Packard Development Company, L.P.Inventors: Raimon Castells De Monet, Jesús Garcia Maza, Francisco Guerrero Carvajal
