  • Method for controlling media feed in an imaging apparatus
    Patent number: 7766444
    Abstract: A method for controlling the media feed of a print media sheet in an imaging apparatus having a media feed roller includes selecting between using absolute positioning of the media feed roller and relative positioning of the media feed roller for various media feed roller moves.
    Type: Grant
    Filed: December 18, 2008

  • Method for operating sheet pick and feed systems for printing
    Patent number: 6729613
    Abstract: One method operates a pick motor and a separate feed motor to pick and feed a sheet for printing. Desired pick and feed motor velocities are obtained from respective first and second functions of sheet position. Sheet position for obtaining both desired motor velocities is determined by the pick system until a predetermined event. The feed-system sheet position is synchronized to the pick-system sheet position upon the happening of the event. Sheet position for obtaining both desired motor velocities is determined by the feed system after the event. Another method operates a printer pick motor and includes starting picking by driving the pick motor in a first direction, to move a sheet forward, with an input sufficient to prevent any teetering transitions between peaks and valleys of an encoder sensor output which would be falsely counted as forward motion by a single-channel encoder.
