Seems to work with the epson backend with some tricks. See <a
href="https://alioth.debian.org/tracker/index.php?func=detail&aid=300562&group_id=1308&atid=410366">this
bugreport</a> for details.

<p>
Multi-function-device. Is detected as "Epson PX-A650". Said to be similar
to Epson CX5200 which is labelled as "untested" by the epson backend.
</p>
<p>
Someone else reports: "Should be similar to the CX-5400, which is reported
to work with the generic sane driver. See <a
href="http://lists.alioth.debian.org/pipermail/sane-devel/2003-December/009678.html">this
link</a>. scanimage immediately reports: "sane_start: Invalid argument".
</p>
<p>
A quick look at the code in gdb shows that the failure occurs when setting
up the half-tone mode. It does get a couple initialization commands
successfully sent before this.

<h1>Want to add or correct information?</h1>
<p>
If anything is wrong or missing on this page please <a href="/bugs.html">file a bug report</a>
or use the <a href="http://www.meier-geinitz.de:80/tinc?key=rDoQ7lrj&#38;formname=adddev" target="_top">the
form for adding an unsupported device</a>.
</p>
<p>
If you own an unsupported scanner, please send as much information as
possible. Especially the output of <em>sane-find-scanner -v -v</em>
and/or <em>cat /proc/scsi/scsi</em> (for SCSI scanners) or <em>cat
/proc/bus/usb/devices</em> (for USB scanners) can help. If you dare to
open the scanner, have a look at the text that's printed on the
chips. That may help to identify the chipset. If you know that the
scanner is similar to another one (e.g. supported by the same Windows
driver), please also mention this fact.
</p>
<h1><a href="/manufacturers.html">Information for Manufacturers</a></h1>
<p>
Are you a manufacturer or vendor of scanners and one of your scanners is
not supported by SANE yet? In this case please have a look at our <a
