sane-hp3900 - SANE backend for RTS8822 chipset based scanners
The sane-hp3900 library implements a SANE (Scanner Access Now Easy)
backend that provides access at least to the following USB flatbed
HP ScanJet 3800 RTS8822BL-03A
HP ScanJet 3970 RTS8822L-01H
HP ScanJet 4070 Photosmart RTS8822L-01H
HP ScanJet 4370 RTS8822L-02A
HP ScanJet G3010 RTS8822L-02A
UMAX Astra 4900/4950 RTS8822L-01H
More details can be found on the hp3900 backend homepage
This is ALPHA software. Keep your hand at the scanner’s plug and unplug
it, if scanner does not start to scan. 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.
The contents of the hp3900.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 39XX
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 hp3900.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
The backend configuration file (see also description of
The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
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).
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_HP3900=4

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.
