Kodak i800 Series User Manual page 34

Sequential counter the scanner assigns a unique Sequential
ID Number to each document which is returned in the image
header. The host application controls the setting of the starting
value for this counter.
Patch Type the scanner indicates if a patch type was
recognized on the document in the image header. If no patch
type is recognized, or if patch reading is not enabled, this value
will be zero. Transfer patch types return a value of 99. Values 1 –
6 are returned respectively for patch types 1 – 6. See the section
on "Controlling image order" earlier in this chapter for examples
of how to use this value from the image header.
NOTE: If the Toggle patch image is returned to the host, the image
header will indicate a Type 4 patch.
