<P>This is why the status code does exist. I think it does not make a

|

difference here if the scanner scans a new page, the backside of a page
|
|
<BR>
|
|
or gets the image from memory. It is not a hack.

|
|
<P>When XSane runs in ADF mode, it does print the error message "no docs"
|
|
<BR>
|
|
when the first sane_start returns with SANE_STATUS_NO_DOCS.
|
|
<BR>
|
|
When there is at least one page scanned XSane does print a message
|
|
<BR>
|
|
"# pages scanned".
