5.2 Calibrating the scanner
If the scanned image color looks unnatural, the scan engine
may need calibrating in order for the sensor to resume its
original precision. To calibrate the scan engine:
1. Connect the power supply to the scanner.
2. Insert the SD card or flash disk and move the guide
lever to the end of right side.
3. Press and hold the power button for about 0.5 second
to power the scanner on.
4. Press and hold the Custom button until the indicator
LED blinks.
5. Insert the calibration card to the feed slot in 5 seconds.
6. The scanner starts calibrating.
7. The calibration chart will move and stop some time then
reject when calibrate done.
Notice : Always keep the calibration card clean and avoid
dirty, scrape or wrinkle that will affect the calibrating
result.
