Calibrate the scanner
Calibrate the scanner to compensate for offsets in the scanner imaging system (carriage head) for ADF
and flatbed scans. Because of mechanical tolerances, the scanner's carriage head might not read the
position of the image accurately. During the calibration procedure, scanner offset values are calculated
and stored. The offset values are then used when producing scans so that the correct portion of the
document is captured.
Scanner calibration should be carried out only if you notice offset problems with the scanned images.
The scanner is calibrated before it leaves the factory. It needs to be calibrated again only rarely.
