Indexing schemes
Documents are scanned to record the information contained on them in
an easily accessible form.
An indexing scheme is used to access or retrieve the information
recorded and is defined during installation for each mode.
The scanner offers the following indexing schemes:
• Single level
• Two level
• Two level offset
• Three level
• Three level offset
Single level indexing
When using single level indexing, the image address assigned to each
document is defined as follows:
• Field A (Level 1) is defined as having a field length greater than 0
• Field B (Level 2) is defined as having a field length of 0
• Field C (Level 3) is defined as having a field length of 0
• Fixed field may be defined, if desired
For example, if you scan a book with 50 pages, the image address has
been defined:
• Field A has a field length of 3 characters
• Field B has 0 characters
• Field C has 0 characters
• Fixed Field has 0 characters

The first page is assigned image address 001. The second page is
assigned image address 002, and so on, through the remainder of the
book.
Any one of the 50 pages may later be located and retrieved using its
unique image address.
