In this case you need to manually define the recognition zones. If
your document does not contain recognition zones, Readiris cannot
process it.

ONING TEMPLATES
When you want to scan many similar looking documents, it might
be useful to apply zoning templates, instead of editing the
recognition zones each time. In a zoning template you indicate what
your documents look like and where the text, picture or tables zones
are located. This way, Readiris only looks in the indicated areas,
saving you a considerable amount of time.
To create a zoning template:

Scan the first document.

Click the Zones tab to edit the zones to your liking.
See Editing the Recognition Zones for more information.

Then click Save to save the zoning template.
