Check Solution
Are you scanning one of the following
types of originals?
When Black & White is not selected:
• Are there colors or coloring in the
paper?
When Color is not selected:
• Is the color in the original very light?
• Is the color in the original very dark,
almost black?
• Is only a very small area of the original
colored?
n When the color mode is set to "Auto", the machine detects whether the original is
black and white or color when the [Color Start] key is tapped. However, when an
original of a type as shown on the left is used, automatic detection may not give
the correct result.
In this event, specify the color mode manually.
