sane-umax1220u(5) SANE Scanner Access Now Easy sane-umax1220u(5) NAME sane-umax1220u - SANE backend for the UMAX Astra 1220U and similar scanners DESCRIPTION The 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 http://umax1220u-sane.sourceforge.net/. 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 (sane-devel@alioth-lists.debian.net). CONFIGURATION Usually, no manual configuration is necessary. The configuration file for this backend resides in /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: #usb vendor product usb 0x1606 0x0010 # Device list for non-linux systems /dev/scanner /dev/usb/scanner0 See sane-usb(5) for information on how to set the access permissions on the usb device files. FILES The backend configuration file: /etc/sane.d/umax1220u.conf The static library implementing this backend: /usr/lib/sane/libsane-umax1220u.a The shared library implementing this backend: /usr/lib/sane/libsane-umax1220u.so (present on systems that support dynamic loading) ENVIRONMENT 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: SANE_DEBUG_UMAX1220U values: 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 Example: export SANE_DEBUG_UMAX1220U=10 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.

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. 14 Jul 2008 sane-umax1220u(5)
