5. DAILY MAINTENANCE
(5) Calibration ends after approximately 10 minutes.
Click the [OK] button to complete calibration.
(6) To check the calibration results, click the [Confirm] button in the Calibration screen (shown in step (2)
above).
(7) The following prompt is displayed. Insert the calibration sheet into the scanner once again as instructed.
(8) 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.)
(9) If the data is normal, calibration is complete. Click the [Close] button and exit the Scanner Adjustment
Program.
(10) If any abnormal data is observed, specify the problem areas as follows:
Select Calibration from the Scanner menu, and then select Specified Part in the Calibration screen.
(11) The mouse arrow cursor changes to a cross cursor when moved over the data. Click the left mouse
button with the mouse positioned over the streak data. The selected area is shown in blue. Repeat this
procedure for any additional streaks.
Areas that have been selected (shown in blue) can be deselected by clicking the left mouse button
again. To deselect all selected areas, click the [Clear] button.
(12) Once all the required areas have been specified, remove the calibration sheet and clean the contact
glass plates and document-scanning table surface. Check the calibration sheet for dust and dirt.
(13) Click the [Execute] button and then follow the instructions displayed on the screen. The procedure will
be the same as that described in Steps (3) to (5) above. (The time required for calibration will vary
according to the number of repeats specified.)
(14) Perform Steps (8) to (10) once more, and verify the calibration results.
