Calibration
The lamp should be calibrated when the scanner is first unpacked from the
shipping carton. Thereafter, you can calibrate whenever you change the lamp, or if
you move the scanner to a new location. The bulb may change position in transit
and the distribution of light must be adjusted to.
> Note The Calibrate Lamp button should be used sparingly.
Calibrating the lamp will save data in the scanner's EEPROM memory. This
type of memory will retain data when power is not supplied, but can only be
written to about 10,000 times. Therefore, lamp calibration should NOT be a daily
procedure.
Before calibrating the unit, any film or film holders must be removed from
the scanner. If this is not done, the scanner will misinterpret the light balance and
attempt to calibrate to a setting that is outside normal limits. Next, close the dust
cover, press the
Calibrate Lamp button and wait until the busy light goes out and
you are returned to the Scanner Tools dialog. This process will take a few minutes
on the LS-3500 and up to 30 seconds on the LS-3510AF. Do not disturb the
scanner or it may not calibrate properly.
The Scanner Tools dialog is closed by pressing the Done button.
Scan Size and Resolution

covering 40 x 40 millimeters. This makes for a scan resolution of 3175 pixels per
inch or 125 pixels per millimeter. All lower resolution scans are derived from this.
