(7) Click the OK button to start scanning.
The scanned data is displayed when scanning is complete. Colors may differ slightly for individual
sensors to make it easier to identify problem areas in calibration. This does not indicate a defect.
Check that there are no vertical streaks, such as white patches, in the scanned data.
(Streaks occur when calibration is not performed correctly due to contamination by dust or dirt.)
(8) If the data is normal, calibration is complete.
Click the Close button and exit calibration mode.
(9) If any abnormal data is observed, clean the sensor glass surface and the document hold-down unit.
Remove the calibration sheet and clean the glass and table surfaces. Check the calibration sheet for
dust.
