The override option must be the first one after the usb line. If you can only scan half of the page, use the PS2Dfw2. The kernel scanner driver scanner module or libusb, the USB library. Other firmware files including the one linked from this page may not work. It’s only necessary if the default or override doesn’t work. Have a look at the SANE download section for some links to binaries.

When you download the gt68xx backend for the first timeuse SANE 1. Without libusb or with older libusb versions all kinds of trouble can be expected. This option can be either used to select the AFE values if automatic coarse calibration is disabled, or to make automatic coarse calibration faster.

Higher debug levels increase the verbosity of the output. When you try the backend, especially with a new or untested scanner, keep your finger at the USB or power connector of your scanner and unplug it if the scanner makes unusual sounds.

These are the scanners that are supported or may be supported by the backend. Thanks for sending patches and answering questions to them and all the other contributors. The scanner should be found by sane-find-scanner without further rgandtech. Please send any comments or support requests to the sane-devel mailing list. It needs an old kernel scanner driver which is supplied with the package.

This is BETA software. An alternative and rather ugly way is to keep the distribution’s sane and xsane packages and to overwrite the sane installation by running configure in the gt68xx package with arguments like this: If it doesn’t find your scanner, there is a problem with access to the USB kernel drivers, a permission problem or sane-backends wasn’t built with libusb support.

You may need to create this directory.

Most scanners should work with sane-backends 1.

The overridefirmwarevendormodeland afe options must be placed after the usb line they refer to. Some scanners need the latest backend from this page, however. When building the backend, check that libusb was detected.

For the latter usage, enable debug level 3 see belowscan an image and look for debug line string with “afe”. It was originally located at http: Some scanners may not work with these binary packages because they weren’t supported at the time 1.

You really need the firmware file for your specific scanner. If you are a beginner and don’t like to compile yourself I recommend to use a current RPM or DEB for Debian of grandtfch if the latest version isn’t already included in your distribution. Don’t ask questions about Windows drivers. A sample configuration file is shown below: Try override “artec-ultima”, sold by Tesco UK.
