NAMEsane-agfafocus - SANE backend for AGFA Focus flatbed scanners
DESCRIPTIONThe sane-agfafocus library implements a SANE (Scanner Access Now Easy) backend that provides access to AGFA Focus flatbed scanners. At present, the following scanners are supported from this backend:
The driver supports line art, 6bpp and 8bpp gray, 18bpp and 24bpp color scans.
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 email@example.com. Have a look at http://www.mostang.com/sane/mail.html concerning subscription to sane-devel.
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.
DEVICE NAMESThis backend expects device names of the form:
Where special is either 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 /dev/sga or /dev/sge, for example. See sane-scsi(5) for details.
CONFIGURATIONThe contents of the 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:
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.
BUGSThe 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 "SANE_DEBUG_AGFAFOCUS=128 scanimage -L" in sh and look for the "disconnect:" line)
DEBUGIf 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.
If you encounter a bug please set the environment variable SANE_DEBUG_AGFAFOCUS to 128 and try to regenerate the problem. Then send me a report with the log attached.
If you encounter a SCSI bus error or trimmed and/or displaced images please also set the environment variable SANE_DEBUG_SANEI_SCSI to 128 before sending me the report.
