If "scanimage -L" doesn't show it, inspect whether or not the SANE backends (i.e. the drivers) for your models are activated in a file like /etc/sane.d/dll.conf (might be elsewhere on CentOS). For HP all-in-one devices which use HP's own free software HPLIP (see http://hplipopensource.com) the SANE backend is "hpaio". For HP flatbed scanners there are some other backends provided the model is supported by SANE, see http://www.sane-project.org/sane-mfgs.html#Z-HEWLETT-PACKARD Even if you use CentOS, the following articles for openSUSE might also be of interest for you because in general SANE should work the same regardless of a particular Linux distribution: http://en.opensuse.org/SDB:Configuring_Scanners in particular the sections about "USB scanner access permissions via udev" and "Trouble-Shooting (Debugging)" http://en.opensuse.org/SDB:How_to_set-up_a_HP_printer in particular in the "Troubleshooting" section: ----------------------------------------------------------------- In general if things do not work, use "hp-check -r" in a terminal to track the issue. ----------------------------------------------------------------- In particular regarding HPLIP see also http://hplipopensource.com/hplip-web/support.html Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5, 90409 Nuernberg, Germany AG Nuernberg, HRB 16746, GF: Markus Rex
