Before you align and calibrate the cameras, make sure that you have cleaned the scan area. An unclean scanning area will give you imprecise calibration results.

Scanner should be warm

Make sure that the scanner has been turned on for at least five minutes prior to camera alignment and calibration. Slight light intensity changes and camera shifting can occur just after turning the scanner on and the warm-up time will ensure that light conditions and camera heights have stabilized.

Insert the calibration sheet

Insert the calibration sheet that came with your scanner. The sheet’s printed side must be inserted face-up. Align the sheet’s midpoint arrow with the scanner’s midpoint arrow and feed the sheet into the scanner.

Start the scanner maintenance utility

Double-click on the WIDEsystem icon to open the program. Press the "Calibrate" button. The "Calibrate" window appears. 

Select "Full Calibration".

The program works in steps to analyze and correct the status of the sensors, calibrate black and white values, and calibrate color (on color scanners). The calibration sheet will be re-scanned a number of times as the program processes data. The wizard will tell you when the process is finished. Click "Close".

Remove calibration sheet

Once calibration has been completed, click the DOWN arrow on the scanner and
remove the calibration sheet from the device. 

Return it to its protective cover and then place it in the storage folder. Store the folder in a dry place and out of direct light.
