True Optical Resolutions
The chart below shows the true optical resolutions (in dpi) available
with each of the original holders. When you scan at one of the resolu-
tion settings listed, one pixel in the scannerÕs image sensor maps
directly to one pixel in the Þnal image. If you use a resolution setting
other than those listed in Table 1, then interpolation (resizing) must be
applied.
To avoid activating the resizer then select a zoom setting that gives one
of the results listed in Table 1 or Table 2. When resizing is used, the
scans take longer and image quality is reduced slightly. The impact this
has on the image quality will vary according to the amount of interpo-
lation required and the contents of your original.
