Shading Correction
 A white standard label is affixed to the rear scale which the machine uses to
calibrate the white balance with light reflected from the LED exposure lamp as
soon as the machine is turned on. Shading is done on the flatbed scanner one
original at a time, regardless of whether the image is FC or B&W.
 When scanning with the ADF, shading correction is done before the first original
is scanned, and then executed again at prescribed intervals (more than one
minute), regardless of whether the originals are FC or B&W.
