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.
