Using the Long Roll Accessory

Punch Sensors
The punch (data hole) sensors are set up at the factory for negative-type film and
require no adjustment during the installation procedure. If you will be scanning film
that has a significantly higher or lower D-min from negative film, such as black-
and-white film or color positive film, see Determining and Setting the Trigger
Points on page D-31.
Setting the Punch Reader Height for the Current Film
Size
Because of differences in film editors, there is no standard punch reader height.
You must set the height of the left and right punch readers, one at a time, to
accommodate your editor.
For each film size that you use:
• Install the appropriate aperture plate.
• Adjust the core locator height on the spindle.
• Thread the film.
• Set the punch reader height (this is a one-time adjustment that can be done
during installation or when the aperture plate is used for the first time).
The aperture plate should already be installed. If not, install it (see Installing the
Aperture Plate on page D-12).
