Patent number: 9770904Abstract: A method of operating a printing system includes identifying groups of nozzles of a plurality of nozzles of a printhead device. The method also includes ejecting fluid drops by the printhead device from nozzles thereof and along corresponding firing paths. The method also includes controlling movement of a detector carriage including a plurality of drop detectors of a drop detector array with respect to the printhead device by a control module to align each one of the drop detectors with the respective firing paths corresponding to the respective nozzles at a predetermined time. The method also includes sensing the firing paths corresponding to the nozzles to detect a presence of the fluid drops by the drop detectors such that each one of the drop detectors senses at a same time a respective firing path corresponding to a respective nozzle for a plurality of groups of nozzles.Type: GrantFiled: December 10, 2012Date of Patent: September 26, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Laura Portela Mata, David Soriano Fosas

Patent number: 8558577Abstract: A signal separation module includes a single-ended bidirectional pin coupled to a processing device, a single-ended unidirectional output pin coupled to a differential signal transceiver, a single-ended unidirectional input pin coupled to the differential signal transceiver, and signal separation logic. The signal separation logic is to detect a current flow condition that indicates the bidirectional pin is asserted by the processing device; assert, as a result of the existence of the current flow condition, the unidirectional output pin and prevent the unidirectional input pin from affecting the bidirectional pin; detect an opposite current flow condition that indicates that the unidirectional input pin is asserted by the differential signal transceiver; and assert, as a result of the existence of the opposite current flow condition, the bidirectional pin and prevent the assertion of the bidirectional pin from affecting the unidirectional output pin.Type: GrantFiled: July 31, 2012Date of Patent: October 15, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Soriano Fosas, Marc Bautista Palacios, Laura Portela Mata

Publication number: 20120153192Abstract: In one example, a media sensing system for a printer includes: a light source; a light sensor for receiving light from the light source; and a portable filter removably supported between the light source and the light sensor. The filter is configured to reduce the amount of light received by the light sensor from the light source. In another example, a method for aligning a media sensing system includes: a light source emitting light toward a light sensor; filtering the emitted light before it reaches the light sensor; the sensor sensing filtered light; and, if a desired amount of filtered light is not sensed by the sensor, then adjusting the position of the light source and/or the light sensor until the desired amount of filtered light is sensed by the sensor.Type: ApplicationFiled: December 20, 2010Publication date: June 21, 2012Inventors: Roger Bastardas Puigoriol, Laura Portela Mata
