Hi<br>
??<br>
<p>
I am having still problems scanning in gray with the <br>
Mustek MFS 1200 SP<br>
[mustek] attach: opening /dev/scanner<br>
[mustek] attach: sending INQUIRY<br>
[mustek] wait_ready: sending TEST_UNIT_READY<br>
[mustek] attach: firmware revision 1.04<br>
[mustek] attach: found Mustek scanner model MFS-12000SP (flatbed scanner), 1-pas<br>
<p>
all the rest sounds quite OK.<br>
But if I tell the sane to use 1 line/buffer the scanner scans for a 10x10nn<br>
area an awful lot more (about 16 times as much :( ).<br>
<p>
It seems to me that the the follwing happens.<br>
....READ_DATA(lpb)<br>
Scanner scannes lpb plus some additional lines (estimate of 16)<br>
Scanner delivers data (maybe it delivers all the data)<br>
sane just read lpb from the buffer<br>
........<br>
<p>
between buffers the Scanner stops for a moment.<br>
<p>
Can someone with a 1200 SP reproduce this ?<br>
<p>
<p>
Gruss<br>
Wolfgang<br>
