Troubleshooting Checklist

The scanner diagnostics test fails.
Problem: The Scanner Diagnostics test( p.80) returns a Test Failed
message.
Cause: The scanning unit may not be in its home position.
Solution: Close the ScanGear CS-U window if it is open. Try turning
the scanner off and back on again by unplugging and
plugging in the USB cable. Then restart your computer.
Colors not what you expect.
Problem: The colors in the preview image appear different from the
colors in the original image.
Cause1: The scanned colors need to be adjusted.
Solution: Make sure the Auto Tone button is selected. If further
adjustments are necessary, use the Tone sheet buttons.
Cause2: The calibration slot on the film guide is obstructed.
Solution: Clear the item blocking the calibration slot.
The preview image of a photograph appears blurred .
Problem: When zooming in on a photograph in the Preview area,
the enlarged image appears blurred.
Cause: The preview scan uses a lower resolution than the final
scan. If you zoom in on a preview image so it is enlarged,
the image will not maintain its resolution in the same way
as the final scanned image.
Solution: Try to use the Zoomed Preview function. Select the image
you wish to zoom. Press and hold the [Shift] key while you
click the [Preview] Button. The selected area of the image
will be pre-scanned in magnified view in the preview area.
