Using the Long Roll Accessory
May 2002 D-31
Appendix D-2: Determining and Setting the Trigger
Points
IMPORTANT: Do this procedure only 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.
1. With the PC powered off, power on the scanner.
2. Wait for the series of 3 beeps to sound at the scanner (or for the lamp to
illuminate).
3. Power on the PC.
Recording the Highest Numbers on the LEDs
IMPORTANT: There must not be film in the scanner.
1. Open the plastic cover.
2. Look at the red LED number on the right side of the Long Roll Accessory.
Note this number as being the “highest” number on the right side.
3. Look at the red LED number on the left side. Note this number as being the
“highest” number on the left side.
4. Record the left and right highest numbers for later calculating the trigger
numbers.
Because the readers are separate, the left and right numbers will not be the
same.
The trigger number tells the scanner when it senses a change in light level. You
need to set the trigger number only once unless you will be using the scanner for
multiple types of film, such as for both negative and positive.
