The Artec backend works best with the AT3 model since that's what I have,<br>
|
||
I even have the same firmware revision as you. I'm wondering if it has<br>
|
||
anything to do with the sense handler. I have received other reports of<br>
|
||
this causing problems a while back.<br>
|
||
<p>
|
||
You can try turning it off by doing a couple things.... Find the following<br>
|
||
section of code in artec.c:<br>
|
||
<p>
|
||
-----------------------------------------------------------<br>
|
||
"AT3", "flatbed",<br>
|
||
8.3, 11, 0, 255, 0, 255, 0, 0, 8, 55, 32768,<br>
|
||
ARTEC_FLAG_CALIBRATE_RGB |<br>
|
||
ARTEC_FLAG_RGB_LINE_OFFSET |<br>
|
||
ARTEC_FLAG_RGB_CHAR_SHIFT |<br>
|
||
ARTEC_FLAG_GAMMA_SINGLE |<br>
|
||
ARTEC_FLAG_SEPARATE_RES |<br>
|
||
ARTEC_FLAG_SENSE_HANDLER |<br>
|
||
ARTEC_FLAG_ONE_PASS_SCANNER,<br>
|
||
"50,100,200,300", "50,100,200,300,600"<br>
|
||
-----------------------------------------------------------<br>
|
||
<p>
|
||
Comment out the line that says "ARTEC_FLAG_SENSE_HANDLER", that will disable<br>
|
||
the sense handler for the AT3. Then go find the first place where<br>
|
||
sanei_scsi_open is called like this:<br>
|
||
<p>
|
||
-----------------------------------------------------------<br>
|
||
DBG (6, "attach: opening %s\n", devname);<br>
|
||
<p>
|
||
status = sanei_scsi_open (devname, &fd, sense_handler, 0);<br>
|
||
if (status != SANE_STATUS_GOOD)<br>
|
||
{<br>
|
||
DBG (1, "attach: open failed (%s)\n", sane_strstatus (status));<br>
|
||
-----------------------------------------------------------<br>
|
||
<p>
|
||
Change the "sense_handler" on the sanei_scsi_open line to a plain "0" (zero).<br>
|
||
That will disable the sense handler being used while trying to detect what<br>
|
||
kind of scanner you have.<br>
|
||
<p>
|
||
Can you try that and see if it works?<br>
