Duplex Scanning
The duplex scanning is extension of simplex mode scanning.
For duplex scanning, SET WINDOW command must specify front
side window (window identifier 00h) and back side window
(window identifier 80h) in window descriptor. SCAN command is
required to invoke duplex mode scanning by sending window
identifier 00h, 80h in data out phase. READ command is issued to
read image data sequentially front window and back window. In the
READ command, window identifier field must be specified in data
type qualifier field to distinguish which side of window data is read.
When front image data is completely read, back image data can be
read in this scanner.
