<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
The <B>sane-umax1220</B> library implements a SANE (Scanner Access Now Easy)
|
|
|
|
|
backend for the the UMAX Astra 1220U scanner.
|
|
|
|
|
|
|

|
|
This backend may also be able to drive the UMAX Astra 2000U. Some peo-
|
|
|
|
|
ple are successful with it, others report that the colors come out ter-
|
|
|
|
|
rible. Your milage may vary.
|
|
|
|
|
|
|
|
|
|
From Stephane (the author of sane-umax_pp), I learned that there are
|
|
|
|
|
differences in the way the color calibration is performed on the 1220U
|
|
|
|
|
and the 2000U and it may account for the problem. Stephane's backend
|
|
|
|
|
support the 2000P, the parallel port sibling to the 2000U. It may be
|
|
|
|
|
possible to use ideas and code from Stephane's backend to add complete
|
|
|
|
|
support for the 2000U to this backend. Since I do not have access to an
|
2005-08-07 11:14:41 +00:00
|
|
|
Astra 2000U, I do not plan to work on this - any volunteers?

<H2>CONFIGURATION</H2><PRE>
|
|
|
|
|
The configuration file for this backend resides in
|
2005-08-07 11:14:41 +00:00
|
|
|
<I>/usr/local/etc/sane.d/umax1220u.conf</I>.
|
2003-09-23 15:30:05 +00:00
|
|
|
|
|
|
|
|
Its contents is a list of device names that correspond to UMAX Astra
|
|
|
|
|
1220U 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
|
|
|
|
|
|
|
|
|
|
When driving a Astra 2000U, use the product number 0x0030. See sane-
|
|
|
|
|
<B><A HREF="usb.5.html">usb(5)</A></B> for information on how to set the access permissions on the usb
|
|
|
|
|
device files.

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:

<H2>KNOWN BUGS</H2><PRE>
|
|
|
|
|
600 dpi scanning may fail for large image sizes.
|
|
|
|
|
|
2005-08-07 11:14:41 +00:00
|
|
|
If you keep getting I/O errors, try cycling the power on your scanner
|
2003-09-23 15:30:05 +00:00
|
|
|
to reset it.
|
|
|
|
|
|
2005-08-07 11:14:41 +00:00
|
|
|
There is no way to cancel a scan, since the driver ignores sane_can-
|
2003-09-23 15:30:05 +00:00
|
|
|
cel().
|
|
|
|
|
|
2005-08-07 11:14:41 +00:00
|
|
|
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
|
2003-09-23 15:30:05 +00:00
|
|
|
default, the scan area is zero.
