sane-umax1220u - SANE backend for the UMAX Astra 1220U scanner DESCRIPTION
The 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 http://umax1220u-sane.sourceforge.net/. 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? CONFIGURATION
The configuration file for this backend resides in /etc/sane.d/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. 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. SEE ALSO

sane-hp3900(5) SANE Scanner Access Now Easy sane-hp3900(5) NAME
sane-hp3900 - SANE backend for RTS8822 chipset based scanners DESCRIPTION
The sane-hp3900 library implements a SANE (Scanner Access Now Easy) backend that provides access at least to the following USB flatbed scanners: Model: Chipset: ------ -------- HP ScanJet 3800 RTS8822BL-03A HP ScanJet 3970 RTS8822L-01H HP ScanJet 4070 Photosmart RTS8822L-01H HP ScanJet 4370 RTS8822L-02A HP ScanJet G2710 RTS8822BL-03A HP ScanJet G3010 RTS8822L-02A HP ScanJet G3110 RTS8822L-02A UMAX Astra 4900/4950 RTS8822L-01H * BenQ 5550 RTS8823L-01E * More details can be found on the hp3900 backend homepage http://sourceforge.net/projects/hp3900-series/. This is ALPHA software. Keep your hand at the scanner's plug and unplug it, if scanner does not start to scan. See also the BUGS section. If you own a scanner other than the ones listed above that works with this backend, please let us know this by sending the scanner's exact model name and the USB vendor and device ids (e.g. from /proc/bus/usb/devices, sane-find-scanner or syslog) to us. Even if the scanner's name is only slightly different from the models mentioned above, please let us know. CONFIGURATION
The contents of the hp3900.conf file is a list of usb lines containing vendor and product ids that correspond to USB scanners. The file can also contain the names of device files that correspond to an HP 39XX scanner. Empty lines and lines starting with a hash mark (#) are ignored. The scanners are autodetected by usb vendor_id product_id statements which are already included into hp3900.conf. "vendor_id" and "product_id" are hexadecimal numbers that identify the scanner. If autodetection does not work, add the device name of your scanner to the configuration file, FILES
/etc/sane.d/hp3900.conf The backend configuration file (see also description of SANE_CONFIG_DIR below). /usr/lib64/sane/libsane-hp3900.a The static library implementing this backend. /usr/lib64/sane/libsane-hp3900.so The shared library implementing this backend (present on systems that support dynamic loading). ENVIRONMENT
SANE_CONFIG_DIR This environment variable specifies the list of directories that may contain the configuration file. Under UNIX, the directories are separated by a colon (`:'), under OS/2, they are separated by a semi-colon (`;'). If this variable is not set, the configura- tion file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value of the environment variable ends with the directory separator character, then the default directories are searched after the explic- itly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".", and "/etc/sane.d" being searched (in this order). SANE_DEBUG_HP3900 If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. Higher debug levels increase the verbosity of the output. Example: export SANE_DEBUG_HP3900=4 SEE ALSO

Scanning is only tested with Linux/ix86/gcc. Be careful when testing on other operating systems and especially on big-endian platforms. The scanner may get wrong data. 06 Jan 2009 sane-hp3900(5)
