Publication number: 20120081426Abstract: Registering images during two sided printing is disclosed. An example is carried out by program code stored on non-transient computer-readable medium. The program code is executable by a processor for printing on a first side of a media a first plurality of plots and a plurality of associated fiducials along an edge of the media. The program code is executable by a processor for determining a distance from the edge of the media to at least one of the plurality of associated fiducials based on sensed input. The program code is executable by a processor for printing a second plurality of plots on a second side of the media based on the distance from the edge of the media so that the second plurality of plots is substantially in registration with the first plurality of plots.Type: ApplicationFiled: February 27, 2011Publication date: April 5, 2012Inventors: Martä Rius Rossell, Carles Flotats Villagrasa, Marcos Casaldaliga

Patent number: 7034279Abstract: A method and apparatus is used to detect and compensate for printhead rotation in an inkjet printer. The detecting operation includes receiving an initial image of a pattern taken from a medium as the printhead passes over the medium, receiving a subsequent image of the pattern taken from the medium as the printhead continues to pass over the medium, comparing the initial image of the pattern and the subsequent image of the pattern taken from the medium and identifying a rotation of the printhead in the inkjet printer passing over the medium if the comparison indicates the initial image of the pattern is rotated relative to the subsequent image of the pattern. The compensation operation includes modifying the timing settings associated with the firing of the nozzles in the inkjet printhead to compensate for the rotation of the printhead.Type: GrantFiled: September 25, 2003Date of Patent: April 25, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Rodrigo Ruiz, Carles Flotats, Francesc Subirada
