sane-cardscan(5) SANE Scanner Access Now Easy sane-cardscan(5) NAME
sane-cardscan - SANE backend for Corex CardScan usb scanners DESCRIPTION
The sane-cardscan library implements a SANE (Scanner Access Now Easy) backend which provides access to the Corex CardScan 800c & 600c small-format scanners. The backend supports only grayscale and color modes and media of (theoretically) infinite length. This backend may support other scanners. The best way to determine level of support is to get a trace of the windows driver in action, and send it to the author. OPTIONS
The cardscan backend supports the following options: mode m Selects the mode for the scan. Options are "Gray" and "Color". CONFIGURATION FILE
The configuration file "cardscan.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: "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 cardscan scanner. "usb /dev/usb/scanner0" (or other device file) Some systems use a kernel driver to access usb scanners. This method is untested. Additionally, there are two configuration options that control the protocol used by the backend: "lines_per_block 16" (or other number from 1 to 32) Controls the number of lines of image data which will be aquired in each pass. Older scanners will require this number set lower, often 1. "has_cal_buffer 1" (1 or 0) Causes the backend to get calibration data from scanner during initialization. Older scanners do not support this request, and must be set to 0. ENVIRONMENT
The backend uses a single environment variable, SANE_DEBUG_CARDSCAN, 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 35 Useless noise KNOWN ISSUES
The scanner does not seem to have much control possible, so the backend cannot set x/y coordinate values, resolutions, etc. These things could be simulated in the backend, but there are plenty of command line tools. The backend also does not send all the commands that the windows driver does, so it may not function the same. The backend does not have the calibration or ejection options of the windows driver.

sane-epjitsu(5) SANE Scanner Access Now Easy sane-epjitsu(5) NAME
sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners. DESCRIPTION
The sane-epjitsu library implements a SANE (Scanner Access Now Easy) backend which provides basic access the Fujitsu fi-60F and ScanSnap S300/S1300 scanners. HARDWARE SUPPORT
These scanners are fairly limited, only supporting a couple of modes and resolutions, and always scanning full width. The backend supports missing modes (binary, grayscale) in software, but makes no effort to offer intermediate resolutions or scan area controls. See KNOWN ISSUES. This backend may support other scanners. If physical inspection reveals an Epson chipset, please contact the author for instructions on collecting a USB trace under Windows to verify. OPTIONS
A limited effort has been made to expose the standard options to the API. This allows a frontend to set resolution, color mode, and choose the ADF setting. The epjitsu 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", "Gray", "Color". resolution, y-resolution Controls scan resolution. Setting --resolution also sets --y-resolution, though this behavior is overridden by some frontends. 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, and that advanced options may be hidden by the frontend. CONFIGURATION FILE
The configuration file "/etc/sane.d/epjitsu.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 fron- tend starts. If the configuration file is missing, the backend will not work. Scanners can be specified in the configuration file in two ways: "usb 0x04c5 0x10c7" (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 supported 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 "firmware /PATH/TO/FILE", allowing you to set the location of the firmware file you have extracted from the Windows driver. Note: This firmware is a copyrighted work of Fujitsu, so cannot be provided by the backend or the author. Please do not ask. Note: These scanners REQUIRE a firmware file to function. See the supplied configuration file for more detail. Note: This option may appear multiple times in the configuration file. It only applies to scanners discovered by 'usb' lines that follow this option. ENVIRONMENT
The backend uses a single environment variable, SANE_DEBUG_EPJITSU, which enables debugging output to stderr. Valid values are: 5 Errors 10 Function trace 15 Function detail 20 Option commands 25 USB trace 30 USB detail 35 Useless noise KNOWN ISSUES
No scan area options are exposed. fi-60F hardware grayscale mode is not used. CREDITS
