NAME¶

sane-kodak - SANE backend for big Kodak flatbed and ADF scanners

DESCRIPTION¶

The sane-kodak library implements a SANE (Scanner Access Now Easy) backend 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

--mode m

--resolution

--tl-x, --tl-y, --br-x, --br-y

--page-width, --page-height

Other options will be available based on the capabilities of the scanner. 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 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 2 ways:

"scsi KODAK"

"scsi /dev/sg0" (or other scsi device file)

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:

KNOWN ISSUES¶

Most hardware options are either not supported or not exposed for control by the user, including: multifeed detection, image compression, autocropping, endorser, thresholding, multi-stream, etc.
