The sane-hp5590 library implements a SANE (Scanner Access Now Easy) backend that provides access to the following Hewlett-Packard Workgroup/Document scanners:

ScanJet 4500C

ScanJet 4570C

ScanJet 5500C

ScanJet 5550C

ScanJet 5590

ScanJet 7650

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.


None required.



The static library implementing this backend.


The shared library implementing this backend (present on systems that support dynamic loading).



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. See used levels below.

Level 10 - generic processing

Level 20 - verbose backend messages

Level 40 - HP5590 high-level commands

Level 50 - HP5590 low-level (USB-in-USB) commands


export SANE_DEBUG_HP5590=50
