[. . . ] The PZ operation start request signal is sent from the main body to rotate the 1st stopper motor (M2) and the 2nd stopper motor (M3), which returns the 1st and 2nd folding stoppers to their waiting/home positions (HP). The paper stopper of the 2nd folding stopper is positioned at the bottom to ensure a normal paper conveyance. When the paper size signal is received from the main body, the 1st stopper motor (M2) is activated to drive the 1st folding stopper. This positions the paper stopper of the 1st folding stopper at a point matching the current paper size. The 1st and 2nd folding stoppers return to their home positions when the FNS operation end signal is received. 1st folding stopper section Paper stoppers HP position FRONT HP position 1st folding stopper 1st stopper motor (M2) 2nd folding stopper section FRONT 2nd folding stopper 2nd stopper motor (M3) Paper stopper HP position 1 - 16 [3] 1st Folding The paper is fed by the registration roller, the conveyance roller, and the conveyance drive roller and carried to the 1st folding stopper through the gate/U. When the front end of the paper touches the 1st folding stopper, the upper middle portion of the paper is curled toward the conveyance drive roller and the 1st folding roller. The front end of the curled paper is pulled into the contact point between these rollers, and the paper is folded. The folded paper is carried to the 2nd folding stopper section. Because the 1st folding roller is driven by the conveyance drive roller through the gear, the rotation speed of both rollers is the same. The 1st folding roller is pressed against the conveyance drive roller and the 2nd folding roller by a spring, ensuring firm contact conditions between the rollers. When the punch mode (sheets are punched) is also enabled in the conveyance section of the main body, the registration motor (M1) and the conveyance motor (M6) temporarily stop upon completion of the 1st folding process to perform the punch action. Then the M1 and M6 restart to resume the z-folding process.

This makes a loop in the paper in the space between the contact face of the 1st and 2nd rollers and the contact face of the 1st folding roller and the conveyance drive roller. The front portion of the loop is pulled into the contact surface between the 1st and 2nd rollers and folded. During folding operation, when the front edge of the paper have passed through the passage PS (PS1), the 2nd stopper motor (M3) operates to move the 2nd folding stopper to the escape position near the waiting position (HP). This action makes sure that the paper is fed normally. 1st folding roller 2nd folding roller Loop Passage PS (PS1) 2nd folding stopper Conveyance drive roller (Surface) (Surface) (Main body) (Reverse side) 1st folding 2nd folding 1 - 18 The paper is carried by the 1st and 2nd folding rollers along the route for the 2nd folding process toward the exit.
