<i>&gt; Hello Sir's,</i><br>
<i>&gt; i am trying to use our old Apple SCSI Greyscale Scanner Typ:</i><br>
<i>&gt; </i><br>
<i>&gt; APPLE SCANNER II 2.02</i><br>
<i>&gt; Model Number: M1381</i><br>
<i>&gt; </i><br>
<i>&gt; with sane and Linux Kernel 2.0.33. The compilation works fine but i can't</i><br>
<i>&gt; get an image from the scanner.</i><br>
<i>&gt; </i><br>
<i>&gt; find-scanner returns the scanner with this devices:</i><br>
<i>&gt; </i><br>
<i>&gt; &lt;computer:~&gt; find-scanner</i><br>
<i>&gt; # You may want to run this program as super-user to find all devices.</i><br>
<i>&gt; # Once you found the scanner devices, be sure to adjust access</i><br>
<i>&gt; # permissions as necessary.</i><br>
<i>&gt; </i><br>
<i>&gt; find-scanner: found scanner "APPLE SCANNER II 2.02" at device /dev/scanner</i><br>
<i>&gt; find-scanner: found scanner "APPLE SCANNER II 2.02" at device /dev/sg3</i><br>
<i>&gt; find-scanner: found scanner "APPLE SCANNER II 2.02" at device /dev/sgd</i><br>
<i>&gt; </i><br>
<i>&gt; but if i try to scan something the following happend:</i><br>
<i>&gt; </i><br>
<i>&gt; &lt;computer:~&gt; scanimage --filename myscan.ppm</i><br>
<i>&gt; 0: 700005000000000e 0000000000000000 p....... ........</i><br>

<i>&gt; 16: 060002022c ....,</i><br>
<i>&gt; scanimage: sane_start: Invalid argument</i><br>
<i>&gt; </i><br>
<i>&gt; if try to select the apple device the following happend:</i><br>
<i>&gt; </i><br>
<i>&gt; &lt;computer:~&gt; scanimage --filename myscan.ppm -d apple:/dev/scanner</i><br>
<i>&gt; Segmentation fault</i><br>
<i>&gt; </i><br>
<i>&gt; I tryed the same tests on an sane system that work fine with an HP Scanner</i><br>
<i>&gt; with the same result, so i assume the problem is the apple part of sane</i><br>
<i>&gt; or my scanner.</i><br>
<i>&gt; </i><br>
<i>&gt; Is there a change to get this scanner work? What can i do?</i><br>
<i>&gt; </i><br>
<i>&gt; greetings</i><br>

<i>&gt; </i><br>
Hello...<br>
<p>
I am the author of the apple backend.<br>
<p>
Unfortunately I cannot help for two reasons<br>
<p>
-I don't have spare time. Maybe after july 8.<br>
<p>
-I don't have the device. The orginal backend was written for sane 0.69<br>
and for<br>
the AppleScanner (4bit 16shades of gray). Yes the two scanner are<br>
similar. Yes the same backend should be used for both. Yes there will be<br>
support when I find time and somebody to help with the debugging.<br>
<p>
For the mean time could you possibly turn on debugging on so we can get<br>
a clue about the crash. Try set the env variable SANE_DEBUG_APPLE to 255<br>
or something like this. Check the mustek man page and change the MUSTEK<br>
to APPLE.<br>
<p>
<p>
