NAME
sane-fujitsu - SANE backend for Fujitsu flatbed and ADF scanners

DESCRIPTION
The sane-fujitsu library implements a SANE (Scanner Access Now Easy) backend which provides access to most Fujitsu flatbed and ADF scanners. This document describes the rewritten backend versions 1.0.21 and greater. The backend supports lineart, halftone, grayscale, and color scanning for most USB and SCSI scanners, depending on hardware capabilities. Most simple scanning related features are exposed. This version features at least basic support for many more models. See KNOWN ISSUES.

HARDWARE SUPPORT
The following scanners are thought to have at least basic scanning capability, either because they have been tested with a prior version, or because documentation indicates they are compatible with a tested model.

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

    ScanStation  M3093E/DE/EX fi-4110EOX2
    ScanPartner  M3096EX      fi-4010CU

    SP-15C/300C

This backend may support scanners not listed here. The best way to determine level of support is to test the scanner directly. Fujitsu equipment has historically been good enough to not be damaged by incorrect commands if the scanner is incompatible. Please contact the author with test results, positive or negative.

OPTIONS
A modest effort has been made to expose the standard options to the API. This allows a frontend to set scanning region, resolution, bit-depth, color mode, and enable the automatic document feeder. The fujitsu backend supports the following basic options for most scanners:

source s
    Selects the source for the scan. Options may include "Flatbed", "ADF Front", "ADF Back", "ADF Duplex".

mode m
    Selects the mode for the scan. Options may include "Lineart", "Halftone", "Gray", and "Color".

resolution, y-resolution
    Controls scan resolution. Setting --resolution also sets --y-resolution but not vice versa. This behavior is overridden by some frontends.

tlx, tly, brx, bry
    Sets scan area upper left and lower right coordinates. Often converted to t, l, x, y by frontend code.

pagewidth, pageheight
    Sets paper size. Used by scanner to determine centering of scan coordinates when using ADF.

Other options will be available based on the capabilities of the scanner. Use 'scanimage --help' to get a list. Be aware that some options may appear only when another option has been set.

CONFIGURATION FILE
The configuration file "fujitsu.conf" is used to tell the backend how to look for scanners, and provide options controlling the operation of the backend. This file is read each time the frontend asks the backend for a list of scanners, generally only when the frontend starts. If the configuration file is missing, the backend will use a set of compiled defaults, which are identical to the default configuration file shipped with SANE.

Scanners can be specified in the configuration file in 4 ways:

"scsi FUJITSU"
    Requests backend to search all scsi busses in the system for a device which reports itself to be a scanner made by 'FUJITSU'.

"scsi /dev/sg0" (or other scsi device file)
    Requests backend to open the named scsi device. Only useful if you have multiple compatible scanners connected to your system, and need to specify one. Probably should not be used with the other "scsi" line above.

"usb 0x04c5 0x1042" (or other vendor/product ids)
    Requests backend to search all usb busses in the system for a device which uses that vendor and product id. The device will then be queried to determine if it is a Fujitsu scanner.

"usb /dev/usb/scanner0" (or other device file)
    Some systems use a kernel driver to access usb scanners. This method is untested.

The only configuration option supported is "buffer-size=xxx", allowing you to set the number of bytes in the data buffer to something other than the compiled-in default, 65536 (64K). Some users report that their scanner will "hang" mid-page, or fail to transmit the image if the buffer is not large enough.

Note: This option may appear multiple times in the configuration file. It only applies to scanners discovered by 'scsi/usb' lines that follow this option.

Note: The backend does not place an upper bound on this value, as some users required it to be quite large. Values above the default are not recommended, and may crash your OS or lockup your scsi card driver. You have been warned.

ENVIRONMENT
The backend uses a single environment variable, SANE_DEBUG_FUJITSU, which enables debugging output to stderr. Valid values are:

    5 Errors
    10 Function trace
    15 Function detail
    20 Option commands
    25 SCSI/USB trace
    30 SCSI/USB detail

OLDER VERSIONS
Backend versions prior to this were numbered with a two part version, or with no version number at all. At the time this version was written, all older versions were retroactively renumbered, 1.0.2 - 1.0.20.

The current backend may have lost support for some feature you were using. The last of the "old" backends, 1.0.20, is still available as source from:

http://www2.pfeiffer.edu/~anoah/fujitsu/

If you find that you need to use the older version, please contact the author, to try and get those features restored to a later version.

KNOWN ISSUES

    All IPC, imprinter, and compression options are disabled.
    Most scanner specific 'quirks' are not accounted for, making it possible to set some options in ways that the scanner does not support.
    Some flatbed options are affected by adf settings.
    Any model that does not support VPD during inquiry will not function.
