sane-kodak(5) SANE Scanner Access Now Easy sane-kodak(5)
NAME
sane-kodak - SANE backend for big Kodak flatbed and ADF scanners
DESCRIPTION
The sane-kodak library implements a SANE (Scanner Access Now Easy) back-
end which provides access to large Kodak flatbed and ADF scanners.
This document describes backend version 7, which shipped with SANE
1.0.21.
SUPPORTED HARDWARE
This version should support models which speak the Kodak SCSI and
Firewire protocols. The i1860 was used to develop the backend, but other
models may work with only minimal modifications. Please see the list at
http://www.sane-project.org/sane-supported-devices.html for an updated
list.
If you have a machine not on that list, or reported as 'untested': the
best way to determine level of support is to test the scanner directly,
or to collect a trace of the windows driver in action. Please contact
the author for help or with test results.
UNSUPPORTED HARDWARE
Most of the recent Kodak consumer or workgroup level machines are based
on other chipsets and are not supported by this backend. Some of these
scanners may be supported by another backend.
OPTIONS
Effort has been made to expose the basic hardware options, including:
--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
Controls scan resolution. Available choices may be limited by
mode.
--tl-x, --tl-y, --br-x, --br-y
Sets scan area upper left and lower right coordinates. These are
renamed -t, -l, -x, -y by some frontends.
--page-width, --page-height
Sets paper size. Used by scanner to determine centering of scan
coordinates when using the ADF (Automatic Document Feeder) and to
detect double feed errors.
Other options will be available based on the capabilities of the scan-
ner. Use scanimage --help to get a list, but be aware that some options
may be settable only when another option has been set, and that advanced
options may be hidden by some frontend programs.
CONFIGURATION FILE
The configuration file kodak.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 con-
figuration file is missing, the backend will use a set of compiled de-
faults, which are identical to the default configuration file shipped
with SANE.
Scanners can be specified in the configuration file in 2 ways:
"scsi KODAK"
Requests backend to search all scsi buses in the system for a de-
vice which reports itself to be a scanner made by 'KODAK'.
"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.
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, 32768 (32K). 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_KODAK, which
enables debugging output to stderr. Valid values are:
5 Errors
10 Function trace
15 Function detail
20 Option commands
25 SCSI trace
30 SCSI detail
35 Useless noise
KNOWN ISSUES
Most hardware options are either not supported or not exposed for con-
trol by the user, including: multifeed detection, image compression, au-
tocropping, endorser, thresholding, multi-stream, etc.
