At present, the following +scanners are supported from this backend: +.PP +.RS +AGFA Focus GS Scanner (6 bit gray scale) (untested) +.br +AGFA Focus Lineart Scanner (lineart) (untested) +.br +AGFA Focus II (8 bit gray scale) (untested) +.br +AGFA Focus Color (24 bit color 3-pass) +.br +AGFA Focus Color Plus (24 bit color 3-pass) +.br +.PP +Siemens S9036 (8 bit gray scale) (untested) +.br +.RE +.PP +The driver supports line art, 6bpp and 8bpp gray, 18bpp and 24bpp +color scans. +.PP +If you own a scanner other than the ones listed above that works with +this backend, please let us know by sending the scanner's model name, +SCSI id, and firmware revision to +.IR sane\-devel@alioth-lists.debian.net . +Have a look at +.I http://www.sane\-project.org/mailing\-lists.html +concerning subscription to sane\-devel. +.PP +All of these scanners are pre-SCSI-2, and do not even report properly +to SCSI Inquiry. This is typically evident in SCSI bus scans, where +the scanner will come up with only garbage as vendor and models strings. + +.SH "DEVICE NAMES" +This backend expects device names of the form: +.PP +.RS +.I special +.RE +.PP +where +.I special +is the path-name for the special device that corresponds to a +SCSI scanner. For SCSI scanners, the special device name must be a +generic SCSI device or a symlink to such a device. Under Linux, such +a device name could be +.I /dev/sga +or +.IR /dev/sge , +for example. See +.BR sane\-scsi (5) +for details. + +.SH CONFIGURATION +The contents of the +.I agfafocus.conf +file is a list of device names that correspond to AGFA Focus +scanners. Empty lines and lines starting with a hash mark (#) are +ignored. A sample configuration file is shown below: +.PP +.RS +/dev/scanner +.br +# this is a comment +.br +/dev/sge +.RE + +.PP +.SH FILES +.TP +.I /etc/sane.d/agfafocus.conf +The backend configuration file (see also description of +.B SANE_CONFIG_DIR +below). +.TP +.I /usr/lib/libsane\-agfafocus.a +The static library implementing this backend. +.TP +.I /usr/lib/libsane\-agfafocus.so +The shared library implementing this backend (present on systems that +support dynamic loading). +.SH ENVIRONMENT +.TP +.B SANE_CONFIG_DIR +This environment variable specifies the list of directories that may +contain the configuration file. On *NIX systems, the directories are +separated by a colon (`:'), under OS/2, they are separated by a +semi-colon (`;'). If this variable is not set, the configuration file +is searched in two default directories: first, the current working +directory (".") and then in +.IR /etc/sane.d . +If the value of the environment variable ends with the directory separator +character, then the default directories are searched after the +explicitly specified directories. For example, setting +.B SANE_CONFIG_DIR +to "/tmp/config:" would result in directories +.IR tmp/config , +.IR . , +and +.I /etc/sane.d +being searched (in this order). +.TP +.B SANE_DEBUG_AGFAFOCUS +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_AGFAFOCUS +values: + +.sp +.ft CR +.nf +Number Remark +\ + 0 print important errors (printed each time) + 1 print errors + 2 print sense + 3 print warnings + 4 print scanner-inquiry + 5 print information + 6 print less important information + 7 print called procedures + 8 print reader_process messages + 10 print called sane\-init-routines + 11 print called sane\-procedures + 12 print sane infos + 13 print sane option-control messages +.fi +.ft R + +.SH MISSING FUNCTIONALITY + +Uploading of dither matrices and tonecurves has been implemented, but +so far has not proven to be useful for anything. For this reason +these options have been disabled. + +.SH BUGS +The scanners that do not support disconnect have problems with SCSI +timeouts if the SCSI bus gets loaded, eg. if you do a kernel build at +the same time as scanning. To see if your scanner supports +disconnect, run +.I "SANE_DEBUG_AGFAFOCUS=128 scanimage \-L" +in a terminal and look for the "disconnect:" line. + +.SH DEBUG +If you have problems with SANE not detecting your scanner, make sure the +Artec backend is disabled. Somehow, this backend causes at least my scanner +not to respond correctly to SCSI inquiry commands. +.PP +If you encounter a bug please set the environment variable +.B SANE_DEBUG_AGFAFOCUS +to 128 and try to regenerate the problem. Then send me a report with the +log attached. +.PP +If you encounter a SCSI bus error or trimmed and/or displaced images please +also set the environment variable +.B SANE_DEBUG_SANEI_SCSI +to 128 before sending me the report. + +.SH TODO +.TP +.B More scanners? + +The AGFA ACS and ARCUS scanners are similar to the FOCUS scanners. +The driver could probably be extended to support these scanners +without too many changes. I do not have access to such scanners, and +cannot add support for it. However, if you are in possession of such +a scanner, I could be helpful in adding support for these scanners. + +The AGFA HORIZON scanners are SCSI-2 scanners, and it would probably +be easier to support these scanners in a SCSI-2 compliant backend. + +.SH SEE ALSO +.BR sane (7), +.BR sane\-scsi (5) + +.SH AUTHOR +Ingo Schneider and Karl Anders \[/O]ygard. |
