.TH sane\-umax1220u 5 "14 Jul 2008" "" "SANE Scanner Access Now Easy"
.IX sane\-umax
.SH NAME
sane\-umax1220u \- SANE backend for the UMAX Astra 1220U and similar scanners
.SH DESCRIPTION
The
.B sane\-umax1220
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
.IR http://umax1220u\-sane.sourceforge.net/ .
.SH UMAX ASTRA 1600U/2000U/2100U SUPPORT
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
.RI ( sane\-devel@alioth-lists.debian.net ).
.SH CONFIGURATION
Usually, no manual configuration is necessary. The configuration file for this backend resides in
.IR /etc/sane.d/umax1220u.conf .
Its content 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:
.nf
#usb vendor product
usb 0x1606 0x0010
# Device list for non-linux systems
/dev/scanner
/dev/usb/scanner0
.fi
See
.BR sane\-usb (5)
for information on how to set the access permissions on the usb device files.
.SH FILES
.TP
The backend configuration file:
.I /etc/sane.d/umax1220u.conf
.TP
The static library implementing this backend:
.I /usr/lib/x86_64-linux-gnu/sane/libsane\-umax1220u.a
.TP
The shared library implementing this backend:
.I /usr/lib/x86_64-linux-gnu/sane/libsane\-umax1220u.so
(present on systems that support dynamic loading)
.SH ENVIRONMENT
.TP
.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:
.B SANE_DEBUG_UMAX1220U
values:
.ft CR
.nf
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
.fi
.ft R
.TP
Example:
export SANE_DEBUG_UMAX1220U=10
.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
.BR 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.

.SH REPORTING BUGS
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
.B SANE_DEBUG_UMAX1220U
set to 10 and attach a copy of the log messages.
