Fig. D-2. GS-700 acquisition window.
The scanning window is marked by grid lines that divide the area into square
centimeters. These are numbered 1–35 top to bottom and 1–21 left to right if the light
source is uncalibrated reflective, and 1–25 top to bottom and 1–20 left to right if the
light source is uncalibrated transmissive (see below for details).
To hide the gridlines, click on the Hide Grid checkbox under Options.
