RECALIBRATING OR CLEANING YOUR SCANNER 119
7. Close the Device Configuration Properties window, and remove
the calibration paper, or cleaning paper and replace it in its plastic
bag.
Note: Do not discard the cleaning paper. You can use it several times.
If additional cleaning is necessary, add a few drops of Isopropyl
alcohol (rubbing alcohol) to the cleaning paper and use it again.
Note: If the calibration page is not available, you can use a piece of
blank white paper as a substitute. However, calibration will not be as
precise as with the regular calibration page.
