Configure the setting to trim the fore edge of Fold & Staple paper.
NOTICE
The folded and stapled sheets are output to the Bundle exit tray. Set the Extension tray of the bundle exit tray as preparation, and open the Stopper. Otherwise, the output paper may drop down from the Bundle exit tray. Also, the full-load detection function of SaddleStitcher SD-506 may not work.
When using thin paper that curls easily for Fold & Staple, output prints so that paper is curled toward the inside. Before outputting a booklet, print out just a few sheets to the Secondary (sub) tray, and check the direction of the curl. If the printed-out sheets are curled upward, the paper is curled inward when a booklet is created.
