Pressing [Adjust] for <Background Density> and making fine adjustments cancels the [Auto] setting for <Background Density>. Similarly, if you press [Auto] for the density after you have adjusted it manually, your adjustments are cancelled. The machine automatically adjusts the density to match the background.
The setting for [Adjust] for <Background Density> is invalid when all of the conditions below are met. The setting is reflected in the image displayed for [Preview], but not for the actual scanned image.
The colour mode is Black & White
The original type is set to Text
The resolution is set to 100 x 100 dpi, 150 x 150 dpi, or 200 x 100 dpi
To activate [Adjust] for <Background Density>, change the settings.
