Print media feed system and control method for the same

摘要

A print media feed system comprises: drive means for moving a feed roller; sensing means for sensing movement of a feed roller; detection means for detecting movement of a pinch roller; and a controller arranged to control the drive means using a gain parameter and signals provided by the detection means and the sensing means. If it is detected that the pinch roller is in a first position in which the pinch roller presses against the feed roller with print media sandwiched therebetween, 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.
