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 134, which  shipped  with  SANE
14       1.0.28.

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

CONFIGURATION FILE

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

ENVIRONMENT

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

KNOWN ISSUES

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