Abstract
An inkjet printing system includes a roller for advancing a recording medium along a recording medium advance direction; an inkjet printhead that ejects drops of ink; a carriage for moving the printhead along a carriage scan direction that is substantially perpendicular or perpendicular to the recording medium advance direction; one or more motors for driving the roller and moving the carriage; a two-dimensional sensor mounted on the carriage which two-dimensional sensor is configured to sense either: a) the recording medium; b) the roller and the recording medium; or c) the roller; and a controller for receiving electrical signals from the two-dimensional sensor and for controlling the one or more motors.
