Comments

The DTWAIN_SetManualDuplexMode function enables or disables the Manual Duplex Mode for the Source Source. If bSet is TRUE, the manual duplex mode is enabled, otherwise it is disabled. Currently, only devices that have document feeders can utilize the manual duplex mode for more than a single duplexed page.

The Flags parameter determines the type of feeder that will be used. The available types are as follows:

Feeder Type	Description
DTWAIN_MANDUP_FACEUPTOPPAGE	Page 1 is placed face up, feeder feeds from the top page of the stack.
DTWAIN_MANDUP_FACEUPBOTTOMPAGE	Page 1 is placed face up, feeder feeds from the bottom page of the stack.
DTWAIN_MANDUP_FACEDOWNTOPPAGE	Page 1 is placed face down, feeder feeds from top of the stack.
DTWAIN_MANDUP_FACEDOWNBOTTOMPAGE	Page 1 is placed face down, feeder feeds from bottom of the stack.

The bSet parameter determines whether the manual duplex mode is turned on or off. If bSet is TRUE, then the manual duplex mode is turned on. If bSet is FALSE, the manual duplex mode is turned off, and the Flags parameter is ignored.
