NAME

6       sane-fujitsu - SANE backend for Fujitsu flatbed and ADF scanners
7

DESCRIPTION

10       The  sane-fujitsu  library  implements a SANE (Scanner Access Now Easy)
11       backend which provides access to most Fujitsu flatbed and ADF scanners.
12
13       This document describes backend version 136, which  shipped  with  SANE
14       1.0.30.

SUPPORTED HARDWARE

18       This  version  supports every known model which speaks the Fujitsu SCSI
19       and SCSI-over-USB protocols. Specifically, the  SCSI  M309x  and  M409x
20       series, the SCSI fi-series, most of the USB fi-series, the USB ScanSnap
21       S5xx/S15xx, and the USB iX1xx/5xx series scanners are supported. Please
22       see the list at http://www.sane-project.org/sane-supported-devices.html
23       for details.
24
25       This backend may support other Fujitsu scanners. The best way to deter‐
26       mine  level of support is to test the scanner directly, or to collect a
27       trace of the windows driver in action.  Please contact the  author  for
28       help or with test results.

UNSUPPORTED HARDWARE

32       The  following scanners are known NOT to work with this backend, either
33       because they have a non-fujitsu chipset, or  an  unsupported  interface
34       type. Some of these scanners may be supported by another backend.

OPTIONS

48       Effort has been made to expose all hardware options, including:
49
50       source s
51              Selects  the source for the scan. Options may include "Flatbed",
52              "ADF Front", "ADF  Back",  "ADF  Duplex",  "Card  Front",  "Card
53              Back", "Card Duplex".
54
55       mode m
56              Selects  the  mode  for the scan. Options may include "Lineart",
57              "Halftone", "Gray", and "Color".
58
59       resolution, y-resolution
60              Controls  scan  resolution.  Setting  --resolution   also   sets
61              --y-resolution, though this behavior is overridden by some fron‐
62              tends.
63
64       tl-x, tl-y, br-x, br-y
65              Sets scan area upper left and lower right coordinates. These are
66              renamed t, l, x, y by some frontends.
67
68       page-width, page-height
69              Sets  paper size. Used by scanner to determine centering of scan
70              coordinates when using ADF and to detect double feed errors.
71
72       Other options will be available based on the capabilities of the  scan‐
73       ner: machines with IPC or DTC will have additional enhancement options,
74       those with CMP will have compression options, those with a printer will
75       have a group of endorser options.
76
77       Additionally,  several  'software'  options are exposed by the backend.
78       These are reimplementations of features  provided  natively  by  larger
79       scanners,  but  running  on  the  host  computer.  This enables smaller
80       machines to have similar capabilities. Please note that these  features
81       are  somewhat  simplistic,  and  may  not perform as well as the native
82       implementations. Note also that these features  all  require  that  the
83       driver  cache  the  entire  image in memory. This will almost certainly
84       result in a reduction of scanning speed.
85
86       Use 'scanimage --help' to get a list, but be aware  that  some  options
87       may  be  settable  only  when  another  option  has  been set, and that
88       advanced options may be hidden by some frontend programs.

CONFIGURATION FILE

92       The configuration file fujitsu.conf is used to tell the backend how  to
93       look for scanners, and provide options controlling the operation of the
94       backend.  This file is read each time the frontend asks the backend for
95       a  list  of  scanners,  generally only when the frontend starts. If the
96       configuration file is missing, the backend will be unable to locate any
97       scanners.
98
99       Scanners can be specified in the configuration file in 4 ways:
100
101       "scsi FUJITSU"
102              Requests  backend  to  search all scsi buses in the system for a
103              device which reports itself to be a scanner made by 'FUJITSU'.
104
105       "scsi /dev/sg0" (or other scsi device file)
106              Requests backend to open the named scsi device. Only  useful  if
107              you  have multiple compatible scanners connected to your system,
108              and need to specify one. Probably should not be  used  with  the
109              other "scsi" line above.
110
111       "usb 0x04c5 0x1042" (or other vendor/product ids)
112              Requests  backend  to  search  all usb buses in the system for a
113              device which uses that vendor and product id.  The  device  will
114              then be queried to determine if it is a Fujitsu scanner.
115
116       "usb /dev/usb/scanner0" (or other device file)
117              Some  systems  use  a kernel driver to access usb scanners. This
118              method is untested.
119
120       The only configuration option supported is "buffer-size=xxx",  allowing
121       you  to  set  the number of bytes in the data buffer to something other
122       than the compiled-in default, 65536 (64K). Some users report that their
123       scanner will "hang" mid-page, or fail to transmit the image if the buf‐
124       fer is not large enough.
125
126       Note: This option may appear multiple times in the configuration  file.
127       It  only applies to scanners discovered by 'scsi/usb' lines that follow
128       this option.
129
130       Note: The backend does not place an upper bound on this value, as  some
131       users  required  it to be quite large. Values above the default are not
132       recommended, and may crash your OS or lockup your scsi card driver. You
133       have been warned.
134

ENVIRONMENT

136       The  backend  uses  a  single environment variable, SANE_DEBUG_FUJITSU,
137       which enables debugging output to stderr. Valid values are:
138
139              5  Errors
140              10 Function trace
141              15 Function detail
142              20 Option commands
143              25 SCSI/USB trace
144              30 SCSI/USB writes
145              31 SCSI/USB reads
146              35 Useless noise
147
148

KNOWN ISSUES

150       Flatbed units may fail to scan at maximum area,  particularly  at  high
151       resolution.
152
153       Any  model  that  does not support VPD during inquiry will not function
154       until an override is added to the backend.
155
156       CCITT Fax compression used by older scanners is not supported.
157
158       JPEG output is supported by the backend, but not by the SANE  protocol,
159       so  is  disabled in this release. It can be enabled if you rebuild from
160       source.
