NAME
sane-avision - SANE backend for original Avision and Avision OEM scanners (HP, Minolta, Mitsubishi, UMAX and possibly more) flatbed scannersABOUT THIS FILE
This file only is a short descripton of the avision-backend for sane!
DESCRIPTION
The sane-avision library implements a SANE (Scanner Access Now Easy) backend that provides access to Avision flatbed scanners and the Avision OEM scanners labelled with HP and Minolta.CONFIGURATION
The configuration file for this backend resides in
/etc/sane.d/avision.conf.
Its contents is a list of device names that correspond to Avision and Avision compatible scanners. Empty lines and lines starting with a hash mark (#) are ignored. A sample configuration file is shown below:
I suggest you hold one hand on the power-button of the scanner while you try the first scans!

option force-a4
option disable-gamma-table
option disable-calibration
option disable-calibration
option one-calib-only
- force-a4:
Forces the backend to overwrite the scanable area
returned by the scanner. This might be needed for
the AV 630 which returns no area - or newer scanners
which retun the area in a unkown format our backend
doesn't recongize yet.
- disable-gamma-table:
Disables the usage of the scanner's gamma-table. You
might try this if your scans hang or only produces
random garbage.
- disable-calibration:
Disables the scanner's color calibration. You
might try this if your scans hang or only produces
random garbage.
- one-calib-only
When this option is enabled, the backend will only
perform a calibration when the backend is initialized
and not before each scan. This might extend the life
of the CCD, but does not work reliable with the newer
USB scanners (they hang sometimes or return garbage
image data). So this option should be used with care.
DEVICE NAMES
This backend expects device names of the form:
- special
Where special is the path-name for the special device that corresponds to a SCSI scanner. The special device name must be a generic SCSI device or a symlink to such a device. The program sane-find-scanner helps to find out the correct device. Under Linux, such a device name could be /dev/sga or /dev/sge, for example. See sane-scsi(5) for details.
