Feature Patch Codes — these patch types can be used by the host for
post-scan image control (they are not used for image addressing). For
example, use these patch types for changing between black and white
and color/grayscale imaging or workflow control.
Patch 1
Patch 4/Toggle Patch
(Do not use these patches for production - they are not to spec)
NOTE: the Toggle patch is a Type 4 patch that is used to trigger the
scanner to switch from the current image stream (black-and-
white) to the alternative image stream (color/grayscale). When
image addressing is disabled, the Patch Readers are also
disabled. However, a Toggle patch can still be detected.For
more information, see the section entitled, "Controlling image
transfer order" in Chapter 2.
Patch 6
