You can manually select the original type according to the type of image that you are scanning. The following three original type modes are available for adjusting the image quality.

IMPORTANT

|
Combinations of these three modes (Text/Photo, Photo, and Text) cannot be selected at the same time. If you select one of these modes, the previously set mode is cancelled.
If you scan an original containing halftones, such as a printed image, using the Photo mode, the moiré effect (a shimmering, wavy pattern) may occur. In this case, you can lessen this moiré effect by using the Sharpness mode. (See "Sharpness.")

NOTE

|
If the original is a transparency, select the original type → adjust the exposure to the most appropriate level for the original.
To adjust the text/photo processing priority level, it is necessary to install the Additional Memory Type B (512MB) to expand the memory capacity of the machine.

This mode is best suited for scanning text originals. Blueprints or pencil drawn originals can also be scanned clearly.
This mode is best suited for scanning photos printed on photographic paper, or photo originals containing halftones (e.g., printed photos).
This mode is best suited for scanning originals containing both text and photos, such as magazines or catalogues.
