Quick Preview
Click this check box to switch the function on and off.
When this function is off, calibration is performed with every preview scan.
When this function is on, calibration is not performed with every preview
scan. The gained calibration data of former scanning will be taken and it
will take shorter time to perform preview scan.
Energy Saving Mode
Click this check box to put the scanner in the energy saving mode. If the
scanner remains idle for the amount of time specified in the Shut off lamp
time box, the scanner lamp switches off. As soon as you start another
scanning job, the lamp switches on again.
Shut off lamp time
This option is enabled when the Energy Saving Mode is switched on. This
sets the amount of scanner idle time that elapses before the scanner
automatically enters the energy saving mode. Select a value (default: 12
min.) within the range 10 to 59 minutes. (Actual time may differ slightly
from the set values.)
Calibration
Click this button to start calibration. Calibration adjusts the color processing
of input and output devices to match the colors in the scanned image with
the colors you see on the computer screen and in the printed image.
During calibration, do not open the scanner's document cover.
