<H2>NAME</H2><PRE>
sane-umax1220u - SANE backend for the UMAX Astra 1220U and similar
scanners
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>sane-umax1220</B> library implements a SANE (Scanner Access Now Easy)
backend for the the UMAX Astra 1220U and similar scanners.
For more information on this backend, please visit
<I>http://umax1220u-sane.sourceforge.net/</I>.
</PRE>
<H2>UMAX ASTRA 1600U/2000U/2100U SUPPORT</H2><PRE>
This backend is also able to drive the UMAX Astra 1600U/2000U/2100U.
The 2100U is confirmed to work. For the other scanners no reports have
been received yet. Please contact us and tell us if your scanner works
(sane-devel@lists.alioth.debian.org).
</PRE>
<H2>CONFIGURATION</H2><PRE>
Usually, no manual configuration is necessary. The configuration file
for this backend resides in <I>/usr/local/etc/sane.d/umax1220u.conf</I>.
Its contents is a list of device names that correspond to UMAX Astra
scanners. Empty lines and lines starting with a hash mark (#) are
ignored. A sample configuration file is shown below:
#usb vendor product
usb 0x1606 0x0010
# Device list for non-linux systems
/dev/scanner
/dev/usb/scanner0
See <B><A HREF="sane-usb.5.html">sane-usb(5)</A></B> for information on how to set the access permissions on
the usb device files.
</PRE>
<H2>FILES</H2><PRE>
The backend configuration file:
<I>/usr/local/etc/sane.d/umax1220u.conf</I>
The static library implementing this backend:
<I>/usr/local/lib/sane/libsane-umax1220u.a</I>
The shared library implementing this backend:
<I>/usr/local/lib/sane/libsane-umax1220u.so</I> (present on systems
that support dynamic loading)
</PRE>
<H2>ENVIRONMENT</H2><PRE>
<B>SANE_DEBUG_UMAX1220U</B>
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend.
E.g., a value of 128 requests all debug output to be printed.
Smaller levels reduce verbosity:
SANE_DEBUG_UMAX1220U values
Number Remark
1 print failures
2 print information
3 print high-level function calls
4 print high-level function checkpoints
9 print mid-level function calls
10 print mid-level function checkpoints
80 print protocol-level function entry
90 print protocol-level function exit
Example:
export SANE_DEBUG_UMAX1220U=10
</PRE>
<H2>KNOWN BUGS</H2><PRE>
600 dpi scanning may fail for large image sizes.
If you keep getting I/O errors, try cycling the power on your scanner
to reset it.
There is no way to cancel a scan, since the driver ignores sane_can
cel().
If you try scanning an image which is too small, you will get I/O
errors. Be sure to adjust the scan area before doing a scan, since by
default, the scan area is zero.

<H2>REPORTING BUGS</H2><PRE>
This backend isn't actively maintained. Nevertheless, bug reports and
comments should be sent to the sane-devel mailing list. When reporting
bugs, please run the backend with SANE_DEBUG_UMAX1220U set to 10 and
attach a copy of the log messages.
