The Patch Reader
The Patch Reader allows you to automatically increment the image
address or initiate a special function. Patch sheets are placed in front of
each document during document preparation or on the lead sheet of a
document.
There are 5 possible patch head positions. The patch head position can
be easily changed. Recognition of all patch types will be returned in the
image header. This is in addition to document level information.
See Kodak publication A-61599, Patch Code Information, for complete
information.

example, use these patch types for changing between bi-tonal and color
imaging or workflow control.

are not to spec.
