<p>When it is decided that the PE sensor installed upstream of the conveying roller has detected paper, the motor driving the recovery operation is stopped. This prevents paper jamming that may be caused by the reverse rotation of the motor during the recovery operation. That is, when print paper happens to remain on a conveying path for some reason, at a position where it can be driven simultaneously by both of the intermediate and the conveying rollers, the activation of the recovery operation, which is powered by the same motor that drives these rollers, can result in paper jamming because the recovery operation causes the conveying roller to rotate in a direction reverse to that of the intermediate roller. The paper jamming can, however, be prevented by stopping the conveying of the paper before it reaches a position where it is driven by the two rollers at the same time.</p> |
