The true 1600 PPI resolution of the Epson 3200 may only be
available when you actually scan at 3200. Scanning at 1600 PPI
will often result in a lower true resolution because the scanner
software skips steps while scanning. That means a faster scan but
not the true 1600 PPI resolution possible on the 3200.
A trick to get a better true resolution is by using an odd PPI
setting like 1605 PPI. The scanner then scans at 3200 and
downsamples to 1605 PPI.
