6.2 Calibrating the scanner
If the scanned image looks fuzzy or there are strange stripes on it, the scanner
may need calibrating in order for the sensor to resume its original precision. To
calibrate the scanner:
1. Follow the instructions of Cleaning the Roller on the preceding section to
clean the roller.
2. Press the Function button until the indicator light starts blinking.
3. Insert the calibration chart to the feeding slot, as shown below:
4. The scanner starts calibrating.
Note:
Keep the calibration chart clean. Any dirt may make the calibration chart
invalid or impact the calibration result.
If you do not have your calibration chart, you will need to order a replacement
online.
