(4) CCD / Lamp
Description
The lamp illuminates the document and the reflected light is transmitted onto the CCDs.The CCDs output
the image signals in level of voltage.
This machine adopts a xenon lamp which is lit quickly when turned on, and the quantity of light is
stable.The lamp is lit when the the control signal CN1-1 for the lamp inverter unit is LOW (0V) .
The table below shows the specification for the CCD.
