.SH NAME
|
|
sane-umax1220u - SANE backend for the UMAX Astra 1220U scanner
|
|
|
|
.SH DESCRIPTION
|
|
|
|
The
|
|
.B sane-umax1220
|
|
library implements a SANE (Scanner Access Now Easy) backend for the
|
|
the UMAX Astra 1220U scanner.
|
|
|
|
For the latest information on this backend, please visit
|
|
.IR http://umax1220u-sane.sourceforge.net/ .
|
|
|
|
.SH UMAX ASTRA 2000U EXPERIMENTAL SUPPORT
|
|
|
|
This backend may also be able to drive the UMAX Astra 2000U.
|
|
Some people are successful with it, others report that the
|
|
colors come out terrible. 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 Astra 2000U, I
|
|
do not plan to work on this -- any volunteers?
|
|
|
|
.SH CONFIGURATION
|
|
|
|
The configuration file for this backend resides in
|
|
@CONFIGDIR@/umax1220u.conf.
|
|
|
|
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-usb(5) for
|
|
information on how to set the access permissions on the usb device files.

.SH FILES

The backend configuration file:

The static library implementing this backend:
|
|
@LIBDIR@/libsane-umax1220u.a
|
|
|
|
The shared library implementing this backend :
|
|
@LIBDIR@/libsane-umax1220u.so

(present on systems that support dynamic loading)

|
.SH ENVIRONMENT
|
|
|
|
.B SANE_DEBUG_UMAX1220U
|
|
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:

.SH KNOWN BUGS
|
|
|
|
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_cancel().
|
|
|
|
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.
