<i>&gt; &gt; Hi,</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt; I am working on support for a Document Feeder for xsane.</i><br>

<i>&gt; &gt; Is there anyone who has a document feeder, best would be</i><br>

<i>&gt;</i><br>
<i>&gt; I have access to an HP IIc with ADF, which I would be pleased to test</i><br>

<i>&gt; or anything :(</i><br>
<i>&gt;</i><br>
<i>&gt; It might be helpful to know that the HP backend provides two SANE</i><br>
<i>&gt; buttons (IIRC) for controlling the ADF. They allow you to run the</i><br>
<i>&gt; top feeder and internal rollers together (replacing the current A4</i><br>
<i>&gt; page with a new A4 page) or run just the internal stuff (unloading</i><br>
<i>&gt; any page inside the scanner).</i><br>
<i>&gt;</i><br>
<i>&gt; It would be nice if XSane learnt to use these SANE buttons to provide</i><br>
<i>&gt; a nice ADF interface, and if all backends provided ADF functionality</i><br>
<i>&gt; in a common way, as much as possible.</i><br>
<i>&gt;</i><br>
<i>&gt; I don't know how (if at all) the HP backend signals the arrival of</i><br>
<i>&gt; the last sheet of paper, but I could test this and report back if</i><br>
<i>&gt; you like. ISTR that SANE standardises "Feeder Empty" errors...</i><br>

Hi Nick,<br>
<p>
I am in contact with David to add some things to the sane api.<br>
One of this is to define how to handle a document feeder.<br>
The idea is very simple:<br>
We define a well known option "mode" that defines the scanmode<br>
such as "Flatbed", "Transparency Adapter" or "Automatic Document Feeder".<br>
<p>
If the option "mode" is set to "Automatic Document Feeder" xsane scans until it<br>
gets an error<br>
(such as out of paper).<br>
<p>
Functions such as unload page or load new page can be realised by a button that<br>
calls a function of the backend, there is nothing that must be defined for it!<br>
<p>
The probelm is that the hp backend is not compatible to this.<br>
The umax backend does work this way so I would prefer a UMAX document feeder.<br>
<p>
Thanks, if I don`t get any other docfeeder, we will see if we can make the hp<br>
backend<br>
compatible!<br>
<p>
Bye<br>
Oliver<br>
