Scanning Troubleshooting

Issue 1: 'xsane' reports error: "Failed to open device: Operation not supported"

Solution:

1.Make sure the line "hpaio" appears in /etc/sane/dll.conf and is not commented out (i.e., no "#" before "hpaio" on the line). Also, note that the "hp" SANE backend (which works with HP Scanjets) is not the same as the "hpaio" SANE backend provided by HPLIP.

2.Try using scanimage to debug the problem: (Note: you may want to comment out SANE backends that you are not using with a "#" character in /etc/sane/dll.conf to make debugging easier)

$ export SANE_DEBUG_DLL=128
$ scanimage -L

Check the output for errors and report them to the HPLIP forum.

Issue 2: OpenOffice or 'xsane' cannot "see" my network connected scanner.

Solution:

For network scanning, the "hp:/net/..." URI must be configured in the CUPS queue for auto-discovery by OpenOffice and xsane. You can manually specify the URI with xsane using the following format:

xsane <"hpaio" device uri>

For example:

xsane hpaio:/net/PSC_750?ip=12.25.63.142

(Where the CUPS installed device URI is: hp:/net/PSC_750?ip=12.25.63.142, and the hp: was replaced with hpaio:)

Issue 3: When scanning multiple sheets with my scanner's ADF, I get an error message.

Solution:

When scanning with the ADF, you must use "batch mode". In 'scanimage', use a command line such as:

$ scanimage -b --batch-scan=yes > output.pnm

In 'xsane', use the provided batch scan mode.
