|SANE Scanner Access Now Easy
sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.
The sane-epjitsu library implements a SANE (Scanner Access Now Easy) backend which provides basic access the Fujitsu fi-60F/fi-65F and ScanSnap S300/S1300(i)/S1100(i) scanners.
These scanners are fairly limited, only supporting a couple of modes and resolutions, and always scanning full width. The backend supports missing modes (binary, grayscale) and intermediate resolutions in software, but provides only minimal scan area controls. See KNOWN ISSUES.
This backend may support other scanners. If physical inspection reveals an Epson chipset, please contact the author for instructions on collecting a USB trace under Windows to verify.
A limited effort has been made to expose the standard options to the API. This allows a frontend to set resolution, color mode, and choose the ADF setting. The sane-epjitsu backend supports the following basic options for most scanners:
Other options will be available based on the capabilities of the scanner. Use 'scanimage --help' to get a list. Be aware that some options may appear only when another option has been set, and that advanced options may be hidden by the frontend.
The configuration file /etc/sane.d/epjitsu.conf is used to tell the backend how to look for scanners, and provide options controlling the operation of the backend. This file is read each time the frontend asks the backend for a list of scanners, generally only when the frontend starts. If the configuration file is missing, the backend will not work.
Scanners can be specified in the configuration file in two ways:
"usb 0x04c5 0x10c7" (or other vendor/product ids)
"usb /dev/usb/scanner0" (or other device file)
The only configuration option supported is "firmware /PATH/TO/FILE", allowing you to set the location of the firmware file you have extracted from the Windows driver.
Note: This firmware is a copyrighted work of Fujitsu, so cannot be provided by the backend or the author. Please do not ask.
Note: These scanners REQUIRE a firmware file to function. See the supplied configuration file for more detail.
Note: This option may appear multiple times in the configuration file. It only applies to scanners discovered by 'usb' lines that follow this option.
The backend uses a single environment variable, SANE_DEBUG_EPJITSU, which enables debugging output to stderr. Valid values are:
10 Function trace
15 Function detail
20 Option commands
25 USB trace
30 USB detail
35 Useless noise
fi-60F and fi-65F hardware grayscale mode is not used, because the calibration code is not finished.
S300 support funded by Microdea, Inc. and Archivista, GmbH.
fi-60F support funded by TrueCheck, Inc.
Improved calibration code provided by Richard Goedeken.
