3. Folding a Stack
A stack is folded by the work of the folding rollers and the paper pushing plate.
The paper pushing plate pushes against the center of a stack toward the roller contact section.
The paper pushing plate starts at its home position and waits at the leading edge position until the
stack has been drawn to the folding roller and is gripped for a length of 10 mm.
When the folding roller has gripped the stack for a length of about 10 mm, the paper pushing
plate motor starts to rotate once again, and the paper pushing plate returns to home position. The
stack so picked by the folding roller is drawn farther by the folding roller and then is moved by the
delivery roller to the paper tray.
