Note

For best results, the scanner should be warmed up for at least 40 minutes

before running camera calibration. Camera calibration requires that you feed

two clean calibration control sheets from the Camera Calibration Kit in

landscape operation.

Caution

Before calibrating either of the scanner's cameras, make sure to close all

open applications on the host PC before you begin. If an open application

attempts to communicate with the scanner during the calibration process,

irreversible problems with the scanner's EGSA board could result!

To calibrate the camera(s), perform the following:

1. Set the scanner in Manual Feeder Mode (refer to the Spectrum XF Operator Manual

for instructions).

2. From the Home menu, press the LEFT ARROW key until the Camera Calibration

menu is displayed.

3. Press one of the following FUNCTION keys: F1 [FRONT]; F2 [BACK]; or F3 [BOTH],

depending on which camera you wish to calibrate. The camera calibration icon will

indicate which camera needs to be calibrated.

4. During the first 40 minutes of scanner operation, the following menu will prompt you

to wait until the scanner and lamps are fully warmed up before calibrating.

5. Press the F1 key [OK] to cancel the calibration and return to the previous menu or

press the F3 key [CALIBRATE] to ignore the warm-up requirement and proceed with

the calibration.

Caution

Ignoring the warm-up requirement may result in degrading color image quality

and is recommended only after lamp replacement. If calibration is performed

during the warm-up period, the scanner will continue to prompt for re-

calibration until a successful calibration is performed after 40 minutes.

6. The control panel LCD prompts the operator to feed the control sheets.
