<EM>&gt; &gt; Hi,
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; The other day, I used my UMAX 2400S scanner to make some copies using
</EM><BR>
<EM>&gt; &gt; the &quot;xerox&quot; script.
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; Today, I wanted to copy some papers; but when I issued the command, I
</EM><BR>
<EM>&gt; &gt; could only get:
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; $ xerox
</EM><BR>
<EM>&gt; &gt; scanimage: open of device umax:/dev/scanner failed: Invalid argument
</EM><BR>
<EM>&gt; &gt; pnmtops: EOF / read error reading magic number
</EM><BR>
<EM>&gt; &gt; lpr: stdin: empty input file
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; Then, to have a quick look at the bus, I ran xcdroast, clicked on
</EM><BR>
<EM>&gt; &gt; SCSI/IDE-Info, exited and the scanner now works again...
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; Huh..?? Looks like xcdroast is able to return the bus to a known state
</EM><BR>
<EM>&gt; &gt; while sane does not...
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; If the sg driver is not loaded when you call scanimage the device sometimes is not found.
</EM><BR>
<EM>&gt; Try xerox again, may be that helps.
</EM><BR>
<P>I should have stated that the driver was likely still loaded as I simply
<BR>
used &quot;uparrow&quot; to recall the previous command which was still onscreen
<BR>
and in the history buffer... I tried this a couple of times with no
<BR>
luck. Then, I power-cycled the scanner and tried again, then thinking
<BR>
&quot;Nuts!&quot;, I got the idea to load xcdroast to check the status of the SCSI
<BR>
bus/devices. When I retried the command, it now worked...
<BR>
<P>I posted this to point out that there may be a recovery glitch in the
<BR>
code on certain errors or conditions.
<BR>
<P>BTW, both LEDs on the scanner were off during the first try (before the
<BR>
power-cycling).
<BR>
<P>HTH,
<BR>
Pierre
<BR>
<P><P><EM>&gt; Bye
