Resolution, zoom, and maximum scannable area
The ID information provides you the following values.
R
MAX
(in dpi) : The maximum scannable area available
X
MAX
(in dots) : The maximum main scan value (at the maximum
resolution, 100% zoom)
Y
MAX
(in dots) : The maximum sub scan value (at the maximum
resolution, 100% zoom)
Based on these values, you can calculate the maximum scannable area
for various resolution and zoom settings according to the following
formulas.
