White portion becomes greyish

Did you perform white level calibration?
White level calibration is used for maintaining the correct colour balance of
scanned images. This white level calibration is needed when using the
scanner cartridge is used for the first time after purchase or when the sys-
tem needs to update the white level calibration data.

Did you adjust the brightness and contrast?
Depending on the image you scan, a white portion is not recognised as
white because the scanner detects and scans even the small differences of
the density between white and other colours.
Adjust the brightness and contrast.
