Is there a problem here?
Nikon packages terrible directions with the standard medium format holder for its high-end scanners. Rather than going crazy with your FH-869S and pining for an FH-869G glass carrier,* let me suggest the following to maximize the usefulness of the medium-format (“Brownie”) carrier that came with your Nikon LS-8000ED or LS-9000ED.
* There is nothing wrong with a glass carrier except dust, inconvenience, skewed negatives, expense, rarity, and a tiny amount of overall resolution loss from the antinewton glass. For some negatives (panoramic, warped, etc.), they are indispensable.
A better way to use your glassless holder:
1. Make sure the rubber grip strips are clean. This is crucial – and probably responsible for most of the complaining about the standard carrier. Clean them with a cotton swab and the alcohol that comes with a cassette tape cleaning kit (or Radio Shack “Non-Slip Fluid,” 44-1013). DO NOT touch the strips with your fingers afterward. Even your skin oil can make them too slick to work.
2. Turn the carrier so that the open-close slider is on the bottom and the end that enters the scanner is on the left side (see the picture at the top). This is going to establish the orientation that you will need for the rest of these directions.
3. Use your forefingers to open the gripper latch at the top. Position the film so that it “corners into” the end of the carrier with the two prongs and the film channel at the top. The end of the filmstrip should be fully supported. Now push the negative strip up toward the ridge at the top of the channel underneath the gripper latch. Get it as even as you can (and it should be possible to get it very, very even). Snap the latch down.
4. Make sure that the open-close slider at the bottom (the one with the “Pac Man” symbol) is in the rightward (“open”) position. Open the bottom gripper latch. Slide the bottom gripper assembly upward until the film edge uniformly contacts the ridge. Be aware that the gripper assembly can be rotated slightly around the open-close slider. You will probably not be able to get it perfect, but the beauty is that you don’t have to. When you have it as close as you can, snap down the film latch.
5. Now gently pull the bottom gripper toward you. Note again that it still pivots around the open-close slider. Get it tight and pivot it until the entire film is flat. This gives you a last chance to make sure that the film is evenly tensioned.
6. While holding the gripper assembly in position, use the last couple of fingers of your strong hand to push the slider left, to the closed position, to lock things down.
7. Run over the film with a rocket blower.
9. Stop complaining about this carrier.
