The Light Tubes

General

The Flextight 848 contains two light tubes: one for illuminating reflective originals from above, the other for shining light through transparencies from below.

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 defective. Make a preview using both types of scans (transparent and reflective) to find out which tube is affected.

If transparencies are not working, then the bottom tube may be burned out.

If reflectives are not working, then the top tube may be burned out.

Follow procedure below to replace a tube:

(See Figure 7 opposite).

1.Get the appropriate replacement lamp (ask your Flextight dealer).

2.Turn off and unplug the scanner from the primary power supply.

3.IMPORTANT: Let the light tubes cool down for app. 10 minutes before proceeding.

3.Remove the front panel (A) by pulling it outwards at the bottom and lift it off.

4.Remove the two black allen screws (B) (one in each side) using a 3 mm allen key. Do not remove any other screws.

5.Remove the two side panels (C) and (D) by lifting them slightly upwards and then outwards.

NOTE! It may require a firm push upwards to release the panels.

6.Turn the feed table (E) to upright position.

7.Locate the tube to be replaced and dismount the plug (F).
