Hello again,<br>
<p>
<i>&gt;&gt;David Mosberger-Tang:</i><br>
<i>&gt;In theory, the Mustek backend can already detect the presence of a</i><br>
<i>&gt;transparency adapter (but it doesn't know much else). If you set</i><br>
<i>&gt;environment variable SANE_DEBUG_MUSTEK to a value &gt;=2, you should see</i><br>
<i>&gt;a message of the form:</i><br>
<p>
[mustek] attach: firmware revision 1.02<br>
[mustek] attach: scanner has automatic line-distance correction<br>
[mustek] attach: found Mustek scanner model MFS-12000SP (flatbed scanner),<br>
1-pass, TA<br>
<p>
thats what my scanner says. But that is not the problem. You can scan normal<br>
documents with the full size even if the TA is _installed_. Only if you tell<br>
the scanner to _use_ trancparency, it switches the two lights and moves the<br>
head. So from this moment on you must scan only 254mm. If you change the<br>
input type back to "Flatbed", you have the full scan area again. So it seems<br>
one must even tell the frontend (if it has a preview) that the area is<br>
smaller while scanning transparent documents?!<br>
<p>
I think I will search my sane documentation first, too many thinks I don't<br>
know about the commuication between the frontend and the backend.<br>
<p>
<i>&gt;Patches for supporting transparancy adapters would be of course very</i><br>
<i>&gt;welcome (I don't have such a beat myself). If you end up playing with</i><br>
<i>&gt;this, let me know and I'll see about getting the Mustek SCSI command</i><br>
<i>&gt;docs to you.</i><br>
<p>
I would like to help, as time permits, but as I said, first I'll check the<br>
docs now...<br>
<p>
Alexander<br>
