Notes

You can adjust the “Sharpness” of the camera image on the menu screen. 46

If the image flickers due to a fluorescent light in the room, either turn off the fluorescent light or set the “Shutter” on the menu screen. 46

Note that the image may still flicker due to the lighting, the document status, the image adjustment, etc., even if the “Shutter” setting is changed.

When finished, turn off the light and close it,

and put back the arm.

Follow the steps of “Preparation of the document imaging camera” in reverse.

Notes

Though this projector uses a 1.45 million pixel camera unit, the images projected on the

screen are 1024 x 768 dot images. If the “Screen size” in the menu screen 46 is set to “Full”, the camera’s full image is compressed to 1024 x 768 dots. If “Thru” is selected, the 1024 x 768 dots at the center of the image are projected.

The light turns off automatically when the arm is inclined.

When the arm is not raised up, the camera source cannot be projected.

In the camera input selected, the sound is not emitted.
