NAME
sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners
DESCRIPTION
The sane-hp5400 library implements a SANE (Scanner Access Now Easy)
backend that provides access to the following Hewlett-Packard USB
flatbed scanners:
ScanJet 5400C
ScanJet 5470C
ScanJet 5490C
More details can be found on the hp5400 backend homepage
http://hp5400backend.sourceforge.net/.
This is ALPHA software. Keep your hand at the scanner’s plug and unplug
it, if the head bumps at the end of the scan area. See also the BUGS
section.
If you own a scanner other than the ones listed above that works with
this backend, please let us know this by sending the scanner’s exact
model name and the USB vendor and device ids (e.g. from
/proc/bus/usb/devices, sane-find-scanner or syslog) to us. Even if the
scanner’s name is only slightly different from the models mentioned
above, please let us know.
CONFIGURATION
The contents of the hp5400.conf file is a list of usb lines containing
vendor and product ids that correspond to USB scanners. The file can
also contain the names of device files that correspond to an HP 54XX
scanner. Empty lines and lines starting with a hash mark (#) are
ignored. The scanners are autodetected by usb vendor_id product_id
statements which are already included into hp5400.conf. "vendor_id"
and "product_id" are hexadecimal numbers that identify the scanner. If
autodetection does not work, add the device name of your scanner to the
configuration file, e.g. /dev/usb/scanner0.
FILES
/etc/sane.d/hp5400.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/usr/lib/sane/libsane-hp5400.a
The static library implementing this backend.
/usr/lib/sane/libsane-hp5400.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_HP5400
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.
Example: export SANE_DEBUG_HP5400=4

BUGS
Scanning is only tested with Linux/ix86/gcc. Be careful when testing on
other operating systems and especially on big-endian platforms. The
scanner may get wrong data.
