NAME
sane-umax - SANE backend for UMAX scanners

ABOUT THIS FILE
This file only is a short descripton of the umax-backend for sane! For detailled informations take a look at sane-umax-doc.dvi or sane-umax-doc.html!

DESCRIPTION
The sane-umax library implements a SANE backend that provides acces to several UMAX-SCSI-scanners and some Linotye Hell SCSI-scanners, parallel- and USB-scanners are not supported! I suggest you hold one hand on the power-button of the scanner while you try the first scans!

CONFIGURATION
The configuration file for this backend resides in
    /usr/local/etc/sane.d/umax.conf. Its contents is a list of device names that correspond to UMAX scanners. Empty lines and lines starting with a hash mark (#) are ignored. A sample configuration file is shown below:
 #scsi Vendor Model Type Bus Channel ID LUN
 scsi UMAX * Scanner * * * * *
 /dev/scanner
 # this is a comment
 /dev/sge The special device name must be a generic SCSI device or a symlink to such a device. To find out to which device your scanner is assigned and how you have to set the permissions of that device, have a look at sane-scsi.

SCSI ADAPTER TIPS
The SCSI-adapters that are shipped with some Umax-scanners are not supported by Linux and most other platforms, so you typically need to purchase another SCSI-adapter that is supported by your platform. See the relevant hardware FAQs and HOWTOs for your platform for more information. The UMAX-scanners do block the scsi-bus for a few seconds while scanning. It is not necessary to connect the scanner to its own SCSI-adapter. But if you need short response time for your SCSI-harddisk (e.g. if your computer is a file-server), I suggest you use an own SCSI-adapter for your UMAX-scanner. See also: sane-scsi(5)

FILES
The backend configuration file:
 /usr/local/etc/sane.d/umax.conf The static library implementing this backend:
 /usr/local/lib/sane/libsane-umax.a The shared library implementing this backend :
 /usr/local/lib/sane/libsane-umax.so
 (present on systems that support dynamic loading)

ENVIRONMENT
SANE_DEBUG_UMAX
 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_UMAX values

 Number  Remark
 0       print important errors (printed each time)
 1       print errors
 2       print sense
 3       print warnings
 4       print scanner-inquiry
 5       print informations
 6       print less important informations
 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
Example:
export SANE_DEBUG_UMAX=8

BUGS
X-resolutions greater than 600 dpi sometimes make problems
