Calibrate the scanner
Your scanner has been calibrated at the factory, and theoretically CIS scanners do not need to be recalibrated
during their lifetimes. Nevertheless, because of environmental changes, your scanner may start showing
image defects that can be easily corrected by recalibrating the scanner. The whole procedure takes less than
10 minutes, and you are recommended to recalibrate the scanner whenever you see some undesired artifact
or a lack of quality in scanned files or copies, bearing in mind the limitations of CIS technology already
explained in this guide. If you perform calibration successfully and still have concerns about the image
quality, please read
Troubleshooting scan-quality issues on page 19 in order to detect whether you are
facing a product limitation, and may want to consider buying a CCD scanner.
