Shading Offset Calibration Instructions

With this calibration, reduce each CIS sensor's density difference caused by the shading
guide's height differences.
Perform Beforehand
(1) Clean the scanner glass surface and the shading guide.
(2) Check to ensure that the shading guide is not snagged on the top cover and that it is
completely flat.
(3) Check to ensure that the top cover is closed securely.
(4) Check that the Printer has already printed the result of the Print Scan Information.
