Section 9: Saving Documents


When Readiris is done processing, the Output File window
opens. Now name your output file.
Note: Readiris, by default, saves all pages to a single output file.
In case you want to generate one file per page, select Create one
file per page.
Note: once you've saved your documents, they are not
automatically removed from the Readiris interface. This way you
have the opportunity to change the settings, if necessary, and to
save your documents in other formats as well.
To start a new project in Readiris:

Click the Trash can icon at the bottom of the Pages panel.
This command erases your document from Readiris so you can
start a new one.
