For detecting continuous media, only the reflective sensor is used. In this case, the reflective
sensor detects the media end only.
LED light amount control:
According to the media selected by the Media Sensor menu (“See Through”, “Reflect”, or “None”),

• Continuous media (None) < Black mark (Reflect) < Label/U-shaped notch (See Through)
