A side edge sensor of a finisher disposed downstream of the stacker detects a lateral shift amount of a sheet conveyed into the finisher. The finisher sends the detected lateral shift amount to the stacker. The stacker receives the lateral shift amount from the finisher, and the stacker controller corrects lateral shift of subsequent sheets based on both the lateral shift amount detected in the stacker and the lateral shift amount sent from the finisher. | 04-28-2011 |
