   * The air assist is adjustable. Always make sure that it's enabled (on the top control panel) and that the valve (on the right hand side) is open. It's okay to reduce the air assist for delicate materials like paper, but there should always be **some** air flow enabled to protect the lens.   * The air assist is adjustable.
