Level rules
A-61510 January 2005
Unlike previous high-volume scanners from Kodak, the i800 Series
Scanners moved the responsibility for defining and controlling level
rules to the host. Level rules are an automated way to control
document image addressing based on the level of the previous
document. The application must define the Level to Follow Level
scheme. For example:
For a 3 level indexing scheme the application must define the
Level to Follow Level rules for level 3, level 2, and level 1.
Level

Level to follow level rules are used to automatically drop to a
lower level. Returning to a higher level is generally done through
patch or application control of the next image address.
