Patent number: 10377161Abstract: In certain examples described herein, a depositing mechanism performs an overcoat depositing operation. The depositing mechanism comprises a plurality of print head arrays. Each print head array is arrangeable in a deposit position to deposit an overcoat layer onto a substrate and a service position to enable servicing to be performed. In certain cases, an array controller causes at least one print head array of the plurality of print head arrays to be moved periodically from the deposit position to the service position according to a predefined servicing sequence during an ongoing overcoat depositing operation performed by the depositing mechanism.Type: GrantFiled: August 21, 2017Date of Patent: August 13, 2019Assignee: HP SCITEX LTD.Inventors: Alex Veis, Ron Tuttnauer

Publication number: 20170217171Abstract: A printhead die assembly includes first and second printhead die. Each of the first and second die has a respective first surface including ink dispensing devices constructed thereon, and a respective second surface opposite the first surface. Each of the first and second die includes nozzles for the ink dispensing devices. The first and second die are positioned so that the second surface of the first die faces the second surface of the second die, and the nozzles of the first die are aligned with the nozzles of the second die.Type: ApplicationFiled: October 6, 2014Publication date: August 3, 2017Applicant: HEWLETT-PACKARD INDUSTRIAL PRINTING LTDInventors: Ken Vandenberghe, Alan Navon, Ron Tuttnauer

Patent number: 9561653Abstract: A printhead assembly includes a printbar beam member and a plurality of printheads disposed thereon. The printbar beam member includes a printbar longitudinal axis. Each one of the printheads includes a printhead longitudinal axis and a row of nozzles arranged parallel to the printhead longitudinal axis. The plurality of printheads are arranged on the printbar beam member in a manner in which each respective printhead longitudinal axis is traverse to the printbar longitudinal axis.Type: GrantFiled: January 26, 2015Date of Patent: February 7, 2017Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Ron Tuttnauer, Alex Veis
