Image Functions
Ex. Width (main scanning direction) = 8.5" = 3,400 (@1/400 inch) = X'D48'
Length (Sub-scanning direction) = 11" = 4400 (@1/400 inch) = X'1130'
Output resolution = 600 dpi
The specification of Width must be;
A#6 = X'0D'
A#7 = X'48'
The specification of Length must be;
A#8 = X'11'
A#9 = X'30'
As a result the output Main Window width and length may be rounded up as follows.
Width =
Length =
* the value in [ ] are rounded up to integer

Specification by the offset (X1, Y1), width (X2) and length (Y2)
This method is called "clipping". Main Window can be set by specifying offset (X1,Y1) , width
(X2) and length (Y2). Each dimension are defined as shown in Figure 3. and Figure 3. The unit
of each dimension is 1/400 inch. These dimensions are defined for front side and back side
independently.
NOTICE: When the Jam detection is set OFF, the scanner ignores the length and continues reading.
