  • Print media edge printing
    Patent number: 7543927
    Abstract: In printing apparatus, when printing near the end of a print media with a printhead having nozzles, a controller causes a print drive to produce a large print media advance movement together with the use of a different group of nozzles from that used for the rest of the print media. This avoids printing art effects as the print media leaves a pinch in a media feed. In one embodiment the number of nozzles used for printing in the end region is reduced, and the centre of the group of nozzles is simultaneously shifted in the direction of print media advance. The size of the print media advance is also changed in the end region. The printing mask used is also changed.

  • Print media drive
    Patent number: 7189018
    Abstract: In a printing apparatus, in which normal printing occurs in a print zone through which a print media is moved by an input feed roller arrangement and an output overdrive roller arrangement, the desired speed of the print media is maintained during bleed printing in the margin of the print media by altering the drive parameters of at least one of the roller arrangements.

  • Dual-axis media-positioning sensor
    Patent number: 7111918
    Abstract: A media-positioning sensor assembly in one embodiment of the invention is disclosed that includes a mechanism and a media-positioning sensor. The mechanism moves back and forth over media along a first axis. The media advances past the mechanism along a second axis perpendicular to the first axis. The media-positioning sensor is situated on the mechanism and is to detect positioning of the media relative to the mechanism along at least one of the first axis and the second axis.
