sane-fujitsu - SANE backend for Fujitsu flatbed scanners



The sane-fujitsu library implements a SANE (Scanner Access Now Easy) backend which provides access to Fujitsu flatbed scanners. At present, the following scanners are known to work with this backend:

Vendor: Model: Rev:
-------- ---------------- -----
FUJITSU M3096Gm 02
FUJITSU fi-4340C
The driver supports lineart, halftone, grayscale, and color (3091 and 3092) scanning depending on hardware capabiliites.

The "Fujitsu" driver is a first attempt at integrating support for all Fujitsu scanners - previously available as different single drivers - in one driver. At present, the M3091DCd is working (lineart, halftone, 8-bit grayscale and 24-bit color, simplex and duplex), and the driver should also support the M3096 as the M3096g driver code has been incorporated. This driver supersedes the old "m3091"/"fujitsu" drivers and the old "m3096g" driver.

Other scanners in these families may work. The ScanPartner 15C seems to be a repackaging of the ScanPartner 600C, but I don't know if it works. Look at the sp15c backend for this scanner. Perusal of the M3096GX/M3093GX/M3093DG manual suggests the M3096G driver offers access to a subset of the new scanners. People are encouraged to try these driver with the other scanners and to contact the author with test results.



The M3091 driver supports duplex scanning. To the front-end, a duplex scan looks very much like scanning two separate pages from the document feeder, i.e. the SANE front-end receives two images instead of one. Front-ends which are not capable of dealing with that - e.g. the command-line tool scanimage - cannot be used for duplex scanning. If you want to do duplex scans from the command line, get Tom Martone's scanadf program from



A modest effort has been made to expose the standard options to the API. This allows frontends such as xscanimage to set scanning region, resolution, bit-depth (and color), and enable the automatic document feeder.
The "Fujitsu" driver supports the following options:
mode m
m may be one of "Color", "Lineart", "Halftone", or "Gray", dependent on the scanner model. It is advisable to specify this option first when using command line tools, as the validity of some of the other options depends on the mode setting.

x, y

Scan width and height

pagewidth, pageheight

Page size; when using the ADF, the driver will assume that a page of the given width is centered

resolution, y-resolution

Controls scan resolution. Permissible values dependent on model and scan mode; setting --resolution also sets --y-resolution but not vice versa. This makes it possible to set the 3091's maximum resolution of 300x600dpi.

brightness b

Only supported for M3096

treshold t

Only supported for M3096

duplex d

d may be "front", "back", or "both" and denotes which sides of the page are to be scanned (duplex scanner only for example 3091, 3093Gd).

lampcolor c

c may be "red", "green", "blue", or "default" - the lamp color to be used when doing graysacale or b/w scans on the M3091.

blueoffset, greenoffset

Color justification options for the M3091; anything other than +1/-1 will probably distort the image. Should be left alone unless your scanner is buggy.


boolean option for the M3091. Only affects duplex scans. If set, a swap file will be used for storing the rear side of a document as it is scanned; otherwise the whole page will be kept in memory.

You may specify the line "forceModel=xxx" in the configuration file to make the driver treat your scanner as an "xxx" scanner (currently supported: 3096, 3091). Use this if you have another scanner that is not automatically detected as being compatible.

The only other configuration option supported is "scsi-buf-size=xxx", allowing you to set the SCSI buffer size to something other than the compiled-in default. Especially with the M3091 scanner, some users had the problem that the scanner would "hang" mid-page, and this can often be alleviated by using "scsi-buf-size=32768".

I'm sure there are plenty, and not too well hidden, but I haven't seen them yet. I don't know if the ScanPartner 15C still works, because I'm not able to test it. 3091/3092 don't support halftone
