Scan Area
WinSPM software defines the center position of the total scan area of the scanner as the
image-offset coordinate (0, 0). It also defines the scan angle with ±180 degrees by
setting 0 degrees as the origin.
Here you specify the ima
current state of the image offset and the scan-rotation angle.
In this window, the current scanning area appears.
The large square shows th
shows the current scanning area in the total scanning area. The shape and position of
the inside square change according to the scan size, the amount of image shift and
the scan rotation angle.
• Setting the Amount of Image Offset
There are 3 methods for setting the amount of image shift, as follows:
• Dragging
Move the cursor to the current scanning area. The cursor will change to the + mark.
Then, drag the cursor to the desired position.
• Using the Offset input boxes
Enter the offset values directly into the Offset input boxes using the keyboard.

The scanner shifts in real-time with the movement of the cursor during drag-
ging, so shift it slowly.
When performing scanning immediately after using the Scan Area, the image
may sometimes become distorted due to hysteresis or creep on the scanner. In
the case of creep, it may take several minutes until image distortion disappears.
