Setting the Magnification

1. On the Mag/Focus tab, select the Chosen Magnification. The value can be

between 0.5 and 2.0.

The scanner’s software maintains an internal Mag/Focus position table that
associates a motor position for each of the possible magnification values.

2. Click Do Magnification.

The lens and CCD move to the chosen position.

Performing an Autofocus

1. On the Mag/Focus tab, enter the Focus Range. The recommended value is

300. The Range is the initial range of travel used for the CCD and lens, in
motor steps.

NOTE: To make the focus procedure faster: if you have focused on a given

magnification, you can set the Range value to be less than 300.

IMPORTANT: Autofocus will be done for the Chosen Magnification. It is

assumed that when you do an Autofocus, you have:

calibrated with an empty film holder (see Calibrating the
Scanner on page A-7)

placed the film to be scanned in the scanner (see Inserting a
Negative or Mounted Slide in the Scanner on page 2-10)

set the scan area (see Using the Capture Tab on page A-8);
for fastest scanning, set the # of pixels (in the Scan area) to
1000

2. Click Do AutoFocus.
