Abstract
A print media feed system comprises: a drive unit configured to move a feed roller; a sensing unit configured to sense movement of a feed roller; a detection unit configured to detect movement of a pinch roller; and a controller arranged to control the drive unit using a gain parameter and signals provided by the detection unit and the sensing unit. If it is detected that the pinch roller is in a first position in which the pinch roller presses against the feed roller such that a print media is between the pinch roller and the feed roller, the gain parameter is set to a first value. If it is detected that the pinch roller is not in the first position, the gain parameter is set to a second value which is lower than the first value.
