Camera calibration Camera calibration is important for maintaining consistent image quality
and should be performed periodically in order to maintain optimum
white balance and camera levels. The scanner's maintenance LED or
the NOU on the Maintenance screen will indicate the need for camera
calibration.
It is recommended that you always calibrate both cameras together,
although they can be calibrated independently. Calibrating both
cameras takes approximately 4-7 minutes.
NOTE: Before calibrating the camera(s):
• Clean the scanner optics thoroughly. See the section
entitled, "Cleaning the optics" earlier in this chapter.
• Make sure the scanner is running in Ready mode (not in
Sleep mode) for at least 5 minutes prior to calibrating.
• Shut down any other scanning application connected to the
scanner.
1. Open the Ngenuity Operator Utility and establish communication
with the scanner.
2. Click on one of the Calibrate links in the Maintenance section of the
NOU Home screen.
The Camera calibration dialog box will be displayed.
3. Click Both, and then click Start. The message, Lift skimmer, then
manually feed the calibration sheet into scanner will be
displayed.
