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 98,  which  shipped  with  SANE
14       1.0.21.

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, and the USB
21       ScanSnap S5xx/S15xx scanners are supported.  Please  see  the  list  at
22       http://www.sane-project.org/sane-supported-devices.html for details.
23
24       This backend may support other Fujitsu scanners. The best way to deter‐
25       mine level of support is to test the scanner directly, or to collect  a
26       trace  of  the windows driver in action.  Please contact the author for
27       help or with test results.

UNSUPPORTED HARDWARE

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

OPTIONS

46       Effort has been made to expose all hardware options, including:
47
48       source s
49              Selects the source for the scan. Options may include  "Flatbed",
50              "ADF Front", "ADF Back", "ADF Duplex".
51
52       mode m
53              Selects  the  mode  for the scan. Options may include "Lineart",
54              "Halftone", "Gray", and "Color".
55
56       resolution, y-resolution
57              Controls  scan  resolution.  Setting  --resolution   also   sets
58              --y-resolution, though this behavior is overridden by some fron‐
59              tends.
60
61       tl-x, tl-y, br-x, br-y
62              Sets scan area upper left and lower right coordinates. These are
63              renamed t, l, x, y by some frontends.
64
65       page-width, page-height
66              Sets  paper size. Used by scanner to determine centering of scan
67              coordinates when using ADF and to detect double feed errors.
68
69       Other options will be available based on the capabilities of the  scan‐
70       ner: machines with IPC or DTC will have additional enhancement options,
71       those with CMP will have compression options, those with a printer will
72       have a group of endorser options.
73
74       Additionally,  several  'software'  options are exposed by the backend.
75       These are reimplementations of features  provided  natively  by  larger
76       scanners,  but  running  on  the  host  computer.  This enables smaller
77       machines to have similar capabilites. Please note that  these  features
78       are  somewhat  simplistic,  and  may  not perform as well as the native
79       implementations. Note also that these features  all  require  that  the
80       driver  cache  the  entire  image in memory. This will almost certainly
81       result in a reduction of scanning speed.
82
83       Use 'scanimage --help' to get a list, but be aware  that  some  options
84       may  be  settable  only  when  another  option  has  been set, and that
85       advanced options may be hidden by some frontend programs.
86

CONFIGURATION FILE

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

ENVIRONMENT

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

KNOWN ISSUES

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