NAME

6       sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.

DESCRIPTION

10       The  sane-epjitsu  library  implements a SANE (Scanner Access Now Easy)
11       backend which provides basic access the  Fujitsu  fi-60F  and  ScanSnap
12       S300/S1300 scanners.

HARDWARE SUPPORT

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) in software, but makes no effort to
19       offer intermediate resolutions or scan area controls. See KNOWN ISSUES.
20
21       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.

OPTIONS

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  epjitsu  backend  supports  the  following  basic
30       options for most scanners:
31
32       source s
33              Selects  the source for the scan. Options may include "Flatbed",
34              "ADF Front", "ADF Back", "ADF Duplex".
35
36       mode m
37              Selects the mode for the scan. Options  may  include  "Lineart",
38              "Gray", "Color".
39
40       resolution, y-resolution
41              Controls   scan   resolution.  Setting  --resolution  also  sets
42              --y-resolution, though this behavior is overridden by some fron‐
43              tends.
44
45       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
48       options may be hidden by the frontend.

CONFIGURATION FILE

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
58       Scanners can be specified in the configuration file in two ways:
59
60       "usb 0x04c5 0x10c7" (or other vendor/product ids)
61              Requests  backend  to  search all usb busses in the system for a
62              device which uses that vendor and product id.  The  device  will
63              then be queried to determine if it is a supported scanner.
64
65       "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
69       The only configuration option supported  is  "firmware  /PATH/TO/FILE",
70       allowing  you  to  set  the  location  of  the  firmware  file you have
71       extracted from the Windows driver.
72
73       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
76       Note:  These scanners REQUIRE a firmware file to function. See the sup‐
77       plied configuration file for more detail.
78
79       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

ENVIRONMENT

84       The backend uses a  single  environment  variable,  SANE_DEBUG_EPJITSU,
85       which enables debugging output to stderr. Valid values are:
86
87              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

95

KNOWN ISSUES

97              No scan area options are exposed.
98              fi-60F hardware grayscale mode is not used.
99              The S1100 is not currently supported, but a patch is available.
