NAME¶
sane-avision - SANE backend for original Avision and Avision OEM scanners (HP, Minolta, Mitsubishi, UMAX and possibly more) flatbed and film scanners.ABOUT THIS FILE¶
This file is a short descripton for the avision-backend shipped with SANE.DESCRIPTION¶
The sane-avision library implements a SANE (Scanner Access Now Easy) backend that provides access to various Avision scanners and the Avision OEM scanners labelled by HP, Minolta, Mitsubishi or Fujitsu.CONFIGURATION¶
The configuration file for this backend resides in /etc/sane.d/avision.conf.# this is a comment option force-a4 option force-a3 option disable-gamma-table option disable-calibration #scsi Vendor Model Type Bus Channel ID LUN scsi AVISION scsi HP scsi /dev/scanner usb 0x03f0 0x0701
- force-a4:
- Forces the backend to overwrite the scanable area returned by the scanner to ISO A4. Scanner that are known to return bogus data are marked in the backend so if you need this option please report this to the backend maintainer. USE WITH CARE!
- force-a3:
- Forces the backend to overwrite the scanable area returned by the scanner to ISO A3. Scanner that are known to return bogus data are marked in the backend so if you need this option please report this to the backend maintainer. USE WITH CARE!
- 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.
- Note:
- Any option above modifies the default code-flow for your
scanner. The options should only be used when you encounter problems with
the default be- haviour of the backend. Please report the need of options
to the backend-author so the backend can be fixed as soon as possible.
DEVICE NAMES¶
This backend expects device names of the form:scsi scsi-spec
usb usb-spec
Where scsi-spec is the path-name to a special device or a device ID for
the device that corresponds to a SCSI scanner. The special device name must be
a generic SCSI device or a symlink to such a device, for example on Linux
"/dev/sga" or "/dev/sg0". The device ID is the ID returned
by the scanner, for example "HP" or "AVISION". See
sane-scsi(5) for details.
- Note:
- Since the backend now includes native USB access, it is no longer needed - even considered obsolete - to access USB scanner via the SCSI emulation (named hpusbscsi on Linux) for Avision USB devices such as the HP 53xx, HP 74xx or Minolta film-scanners.
FILES¶
- /etc/sane.d/avision.conf
- The backend configuration file (see also description of SANE_CONFIG_DIR below).
- /usr/lib/arch_triplet/sane/libsane-avision.a
- The static library implementing this backend.
- /usr/lib/arch_triplet/sane/libsane-avision.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 configuration 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 explicitly 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_AVISION
- 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. The debug level
7 is the author's prefered value to debug backend problems.
