ABSTRACT:
An imaging apparatus includes a motor including a motor shaft to which a pinion gear is attached, and a feed roller including a shaft. The feed roller is positioned upstream from the print zone in relation to the sheet feed direction. A primary gear train includes a first gear in mesh with the pinion gear and a second gear rigidly mounted to the shaft of the feed roller. A spring coupling has a first end connected to the second gear of the primary gear train. A secondary gear train includes a third gear in mesh with the pinion gear and a fourth gear rotatably mounted to the shaft of the feed roller for free rotation with respect to the shaft, the second end of the spring coupling being connected to the fourth gear of the secondary gear train.
