If you were having striping problems and the CCD calibration simply
didnÕt help, then the source of the problem may lie elsewhere, see the
ÒTroubleshootingÓ section of this binder for advice.

The Light Tubes

Orientation of the Light Tubes

The Flextight Precision II contains two light tubes: one for illuminating
reßective originals from above, the other for shining light through
transparencies from below. The lower light tube also provides the light
for the light table.
Each of the light tubes is Þtted with a different sleeve, which must be
aligned correctly inside the scanner. The sleeves help direct the light to
achieve maximum illumination of the original. When you replace the
light tubes, you must make sure the sleeves are aligned correctly.
Some times, the sleeves are glued into place when the scanner is Þrst
shipped from the factory, but when you replace a light tube, the sleeve
will not be glued; it will be tight so that it can not slip freely, but you
will be able to rotate it manually if you try. The correct orientation of
the sleeves is shown in Figure 8.

Replacing the Light Tubes

If your scans are suddenly coming out black (or all white if you are
scanning negatives), then one of your light tubes may be burned out or
misaligned. Test both types of scans (transparent and reßective) to Þnd
out which tube is affected.
¥ If transparencies are not working, then the bottom tube may be
burned out or misaligned.
¥ If reßectives are not working, then the top tube may be burned out.
See ÒCut-Away ViewÓ on page 10 for a picture that shows the two
tubes.
