6 sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.
7
10 The sane-epjitsu library implements a SANE (Scanner Access Now Easy)
11 backend which provides basic access the Fujitsu fi-60F/fi-65F and
12 ScanSnap S300/S1300(i)/S1100(i) scanners.
13
16 These scanners are fairly limited, only supporting a couple of modes
17 and resolutions, and always scanning full width. The backend supports
18 missing modes (binary, grayscale) and intermediate resolutions in soft‐
19 ware, but provides only minimal scan area controls. See KNOWN ISSUES.
20 This backend may support other scanners. If physical inspection reveals
22 an Epson chipset, please contact the author for instructions on col‐
23 lecting a USB trace under Windows to verify.
24
27 A limited effort has been made to expose the standard options to the
28 API. This allows a frontend to set resolution, color mode, and choose
29 the ADF setting. The sane-epjitsu backend supports the following basic
30 options for most scanners:
31 source s
33 Selects the source for the scan. Options may include "Flatbed",
34 "ADF Front", "ADF Back", "ADF Duplex".
35 mode m
37 Selects the mode for the scan. Options may include "Lineart",
38 "Gray", "Color".
39 resolution, y-resolution
41 Controls scan resolution. Setting --resolution also sets
42 --y-resolution, though this behavior is overridden by some
43 frontends.
44 Other options will be available based on the capabilities of the scan‐
46 ner. Use 'scanimage --help' to get a list. Be aware that some options
47 may appear only when another option has been set, and that advanced op‐
48 tions may be hidden by the frontend.
49
51 The configuration file /etc/sane.d/epjitsu.conf is used to tell the
52 backend how to look for scanners, and provide options controlling the
53 operation of the backend. This file is read each time the frontend asks
54 the backend for a list of scanners, generally only when the frontend
55 starts. If the configuration file is missing, the backend will not
56 work.
57 Scanners can be specified in the configuration file in two ways:
59 "usb 0x04c5 0x10c7" (or other vendor/product ids)
61 Requests backend to search all usb buses in the system for a de‐
62 vice which uses that vendor and product id. The device will then
63 be queried to determine if it is a supported scanner.
64 "usb /dev/usb/scanner0" (or other device file)
66 Some systems use a kernel driver to access usb scanners. This
67 method is untested.
68 The only configuration option supported is "firmware /PATH/TO/FILE",
70 allowing you to set the location of the firmware file you have ex‐
71 tracted from the Windows driver.
72 Note: This firmware is a copyrighted work of Fujitsu, so cannot be pro‐
74 vided by the backend or the author. Please do not ask.
75 Note: These scanners REQUIRE a firmware file to function. See the sup‐
77 plied configuration file for more detail.
78 Note: This option may appear multiple times in the configuration file.
80 It only applies to scanners discovered by 'usb' lines that follow this
81 option.
82
84 The backend uses a single environment variable, SANE_DEBUG_EPJITSU,
85 which enables debugging output to stderr. Valid values are:
86 5 Errors
88 10 Function trace
89 15 Function detail
90 20 Option commands
91 25 USB trace
92 30 USB detail
93 35 Useless noise
94
97 Only limited scan area options are exposed.
98 fi-60F and fi-65F hardware grayscale mode is not used, because
99 the calibration code is not finished.
