SCANGEAR TOOL INSTALL
Install sane-utils and see if the scanner is detected with That's fine, but it tells us nothing about whether we can get the device scanning. There is an Epson Stylus Photo on USB Bus 002 and at Device 005. Suitable backends to use for scanning are sane-escl and sane-airscan.Ĭonnect the scanner to the computer and see what lsusb lsusbīus 002 Device 005: ID 04b8:080f Seiko Epson Corp. On Debian 11 (bullseye), a modern scanner device that provides the IPP-over-USB protocol will be automatically set up to use the protocol, provided ipp-usb is installed and the service is loaded, active and running.
SCANGEAR TOOL MANUAL
Each backend has its own manual page and a configuration file in /etc/sane.d. The SANE manual lists the backends available. Your scanner should work out-of the-box with a frontend without bothering with any of the next steps, but it is as well to be aware there are troubleshooting procedures that can be followed. The next two sections assume you have the backend (and other files) that SANE or the vendor supply. A notable free backend source requiring this step is the one for the all-in-one machines from HP. If the scanner is not supported by SANE, the backend (and other files) will have to be obtained from the Debian archives or the vendor.
The package also provides SANE's collection of scanner backends. The first step on the road to successful scanning is to install libsane or libsane1, which has the central library for operating scanners. Those scanners that SANE directly supports with backends are listed here.
SCANGEAR TOOL SOFTWARE
Backends not provided by SANE can easily be accomodated within the SANE scanning framework whether the software is free ( HP) or non-free. The Project provides a collection of scanner backends (drivers) that can communicate with the scanner in order to operate it.
Scanning a document from a standalone scanner or a multi-function device generally involves using SANE (Scanner Access Now Easy).
