The PT33MFB (multi-function bookletmaker) comes with two feeding bins as well as heavy duty stitching heads and face trim. The MFB is capable of creasing, perforating, and partial perforating in one pass. Automatically creasing inline helps prevent toner cracking on heavier weight covers and the perforating options eliminate the need to process sheets beforehand. The PT33MFB is also equipped with a patented progressive crease function, which creates a square back booklet feel and prevents cracking on the thick cover stock.
