NAME
sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.
DESCRIPTION
The sane-epjitsu library implements a SANE (Scanner Access Now Easy)
backend which provides basic access the Fujitsu fi-60F and ScanSnap
S300/S1300 scanners.
HARDWARE SUPPORT
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) in software, but makes no effort to
offer intermediate resolutions or 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.
OPTIONS
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 epjitsu backend supports the following basic
options for most scanners:
source s
Selects the source for the scan. Options may include "Flatbed",
"ADF Front", "ADF Back", "ADF Duplex".
mode m
Selects the mode for the scan. Options may include "Lineart",
"Gray", "Color".
resolution, y-resolution
Controls scan resolution. Setting --resolution also sets
--y-resolution, though this behavior is overridden by some
frontends.
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.
CONFIGURATION FILE
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)
Requests backend to search all usb busses in the system for a
device which uses that vendor and product id. The device will
then be queried to determine if it is a supported scanner.
"usb /dev/usb/scanner0" (or other device file)
Some systems use a kernel driver to access usb scanners. This
method is untested.
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.
ENVIRONMENT
The backend uses a single environment variable, SANE_DEBUG_EPJITSU,
which enables debugging output to stderr. Valid values are:
5 Errors
10 Function trace
15 Function detail
20 Option commands
25 USB trace
30 USB detail
35 Useless noise
KNOWN ISSUES
No scan area options are exposed.
fi-60F hardware grayscale mode is not used.
