Section: SANE Scanner Access Now Easy (5)
Updated: 06 Jan 2009
The sane-hp3900 library implements a SANE (Scanner Access Now Easy) backend that provides access at least to the following USB flatbed scanners:
Model: Chipset: ------ -------- HP ScanJet 3800 RTS8822BL-03A HP ScanJet 3970 RTS8822L-01H HP ScanJet 4070 Photosmart RTS8822L-01H HP ScanJet 4370 RTS8822L-02A HP ScanJet G2710 RTS8822BL-03A HP ScanJet G3010 RTS8822L-02A HP ScanJet G3110 RTS8822L-02A UMAX Astra 4900/4950 RTS8822L-01H * BenQ 5550 RTS8823L-01E *
More details can be found on the hp3900 backend homepage http://sourceforge.net/projects/hp3900-series/.
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 configuration file,
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.
