Abstract
A method for monitoring relative position of a carriage and a recording medium in an inkjet printing system having a roller for advancing the recording medium along a recording medium advance direction, the method includes sending light from a light source toward at least a portion of the roller; receiving reflected light in a two-dimensional sensor mounted on the carriage; sending a signal from the two-dimensional sensor to a controller, wherein the signal indicates the pattern of reflected light received by the two-dimensional sensor; comparing the received signal by the controller to a signal stored in memory; and calculating a shift between the received signal and the signal stored in memory.
