The following table summarizes the scanner functions and
settings available on your scanner. These functions are
controlled by the commands from your scanner software.

Resolution guidelines
The table below shows the recommended resolutions in dots
per inch or pixels per inch for the image types and printing
or display methods. You may want to experiment with your
scanner settings, possibly using a cropped version of your
image to save time, until you achieve the desired results.
The resolution that you use to scan an image (input
resolution) does not have to match the dots per inch of your
printer (output resolution). Input and output resolution are
two quite different measurements.

Data format
The data format specifies the number of bits used to
represent the tone of a pixel. The data format can be set in the
range of 1 bit to 8 bits per pixel per color.
As the value increases, more tones and colors can be
captured in the scanned image as shown in the following
table:
Data format
