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 button
until the indicator LED blinks.
6. Insert the calibration card to the
feed slot in 5 seconds.
7. The scanner starts calibrating.
8. The calibration chart will move
and stop some time then reject
when calibrate done.
Always keep the
calibration card clean
and avoid dirty, scrape or
wrinkle that will affect the
calibrating result.
5. Remove the blue protective film
from the calibration card before
use.
