sane-umax1220u - SANE backend for the UMAX Astra 1220U and similar scanners
<P>
<A NAME="lbAC">&nbsp;</A>
<H2>DESCRIPTION</H2>
<P>
The
<B>sane-umax1220</B>
library implements a SANE (Scanner Access Now Easy) backend for the
the UMAX Astra 1220U and similar scanners.
<P>
For more information on this backend, please visit
<I><A HREF="http://umax1220u-sane.sourceforge.net/">http://umax1220u-sane.sourceforge.net/</A></I>.
<P>
<A NAME="lbAD">&nbsp;</A>
<H2>UMAX ASTRA 1600U/2000U/2100U SUPPORT</H2>
<P>
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
(<A HREF="mailto:sane-devel@alioth-lists.debian.net">sane-devel@alioth-lists.debian.net</A>).
<P>
<A NAME="lbAE">&nbsp;</A>
<H2>CONFIGURATION</H2>
<P>
Usually, no manual configuration is necessary. The configuration file for this backend resides in
<I>@CONFIGDIR@/umax1220u.conf</I>.
<P>
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:
<P>
<PRE>
#usb vendor product
usb 0x1606 0x0010
# Device list for non-linux systems
/dev/scanner
/dev/usb/scanner0
</PRE>
<P>
See <A HREF="/cgi-bin/man/man2html?5+sane-usb">sane-usb</A>(5) for information on how to set the access permissions on the usb
device files.

<DT id="4"><B>SANE_DEBUG_UMAX1220U</B>
<DD>
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:
<P>
SANE_DEBUG_UMAX1220U values

<PRE>
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

<H2>KNOWN BUGS</H2>
<P>
600 dpi scanning may fail for large image sizes.
<P>
If you keep getting I/O errors, try cycling the power on your scanner to reset it.
<P>
There is no way to cancel a scan, since the driver ignores sane_cancel().
<P>
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>
<P>
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.
