Table of Contents

Documents in the compiler tray are assembled towards the front. For center stapling and folding positions, one

set of document is assembled and moved to the center.

The booklet end guide is lifted to where the fold will divide the paper into two equal halves. When the printouts

are stapled, the booklet end guide will be raised so that the stapled position is at the folding position. The

stapling position is slightly lower than the folding position center line.

When the movement from the booklet folding/exit drive motor is transferred to the knife through the engagement

of the sector gear, the knife will thrust forward and then return to the original position after one full rotation. At the

folding position, the knife is thrust forward to fold the paper between booklet folding roll and booklet folding nip

Paper is folded into two halves by the booklet folding roll driven by the booklet folding/exit drive motor and is

delivered to the booklet media bin by the booklet media exit roll assembly. The booklet media bin belt will move

at a fixed interval for every set of booklets that are created.
