sane-epkowa(5) File Formats Manual sane-epkowa(5) NAME sane-epkowa - SANE backend for EPSON scanners DESCRIPTION The sane-epkowa library implements a SANE (Scanner Access Now Easy) backend that provides access to EPSON flatbed scanners. This backend should be considered alpha-quality software! At present, the following scanners are known to work with this backend: Model: japan other ---------------- ------------------- GT-6600U Perfection 610 GT-6700U Perfection 640U GT-7200U Perfection 1250 Perfection 1250 PHOTO GT-7300U Perfection 1260 Perfection 1260 PHOTO GT-7600S Perfection 1200S GT-7600U Perfection 1200U GT-7600UF Perfection 1200U PHOTO GT-7700U Perfection 1240U GT-8300UF Perfection 1660 PHOTO GT-8700 Perfection 1640SU GT-8700F Perfection 1640SU PHOTO GT-8200U Perfection 1650 GT-8200UF Perfection 1650 PHOTO GT-9300UF Perfection 2400 PHOTO GT-9400 Perfection 3170 PHOTO GT-9700F Perfection 2450 PHOTO GT-9800F Perfection 3200 PHOTO GT-F500 Perfection 2480 PHOTO GT-F520 Perfection 3490 PHOTO GT-F550 Perfection 2580 PHOTO GT-F570 Perfection 3590 PHOTO GT-F600 Perfection 4180 PHOTO GT-F650 Perfection V100 PHOTO GT-F670 Perfection V200 PHOTO GT-F700 Perfection V350 PHOTO GT-S600 Perfection V10 GT-X700 Perfection 4870 PHOTO GT-X750 Perfection 4490 PHOTO GT-X770 Perfection V500 PHOTO GT-X800 Perfection 4990 PHOTO GT-X900 Perfection V700/V750 ES-2000 Expression 1600 ES-2200 Expression 1680 ES-6000 GT-10000 ES-6000H GT-10000+ ES-6000HS ES-7000H GT-15000 ES-8500 Expression 1640XL ES-9000H GT-30000 ES-10000G Expression 10000XL ES-H300 GT-2500 Stylus CX2800/CX2900/ME200 PX-A550 Stylus CX3500/CX3600 Stylus CX3700/CX3800/DX3800 PX-A620 Stylus CX3900/DX4000 Stylus CX4100/CX4200/DX4200 Stylus CX4300/CX4400/CX5500/CX5600/DX4400 Stylus CX4500/CX4600 PX-A650 Stylus CX4700/CX4800/DX4800 Stylus CX4900/CX5000/DX5000 CC-600PX Stylus CX5100/CX5200 Stylus CX5300/CX5400 PX-A720 Stylus CX5900/CX6000/DX6000 Stylus CX6300/CX6400 Stylus CX6500/CX6600 PX-A640 Stylus CX7300/CX7400/DX7400 Stylus CX7700/CX7800 PX-A740 Stylus CX8300/CX8400/DX8400 PX-FA700 Stylus CX9300F/CX9400Fax/DX9400F PM-A700 Stylus Photo RX420/RX425/RX430 Stylus Photo RX500/RX510 PM-A750 Stylus Photo RX520/RX530 PM-A820 Stylus Photo RX560/RX580/RX590 PM-A840 Stylus Photo RX585/RX595/RX610 PM-A850 Stylus Photo RX600 PM-A870 Stylus Photo RX620/RX630 PM-A890 Stylus Photo RX640/RX650 PM-A940 Stylus Photo RX680/RX685/RX690 PM-A900 Stylus Photo RX700 PM-A920 PM-A950 PM-A970 PM-T960 PM-T990 LP-A500 AcuLaser CX11 AcuLaser CX21 LP-M5500 LP-M5600 For other scanners the software may or may not work.

OPTIONS The options the backend supports can either be selected through command line options to programs like scanimage or through GUI elements in xs- canimage or xsane. Valid command line options and their syntax can be listed by using scanimage --help -d epkowa Not all devices support all options. Scan Mode The --mode switch selects the basic mode of operation of the scanner valid choices are Binary, Gray and Color. The Binary mode is black and white only, Gray will produce up to 256 levels of gray and Color means 24 bit color mode. Some scanners will internally use 36 bit color, the external interface however does only support 24 bits. The --dropout option determines which color filters are used to scan in Binary mode. Valid choices are None, Red, Green and Blue. The --halftoning switch selects the mode that is used in Binary mode. Valid options are None, Halftone A (Hard Tone), Halftone B (Soft Tone), Halftone C (Net Screen), Dither A (4x4 Bayer), Dither B (4x4 Spiral), Dither C (4x4 Net Screen), Dither D (8x4 Net Screen), Text Enhanced Technology, Download pattern A, and Download pattern B. The --dropout switch selects the so called dropout color. Vald options are None, Red, Green and Blue. The default is None. The dropout color is used for monochrome scanning and selects the color that is not scanned. This can be used to e.g. scan an original with a colored background. The --brightness switch controls the brightness of the scan. Valid options are the numbers from -3 to 3. The default is 0. The larger the brightness value, the brighter the image gets. If a user defined table for the gamma correction is selected, the brightness parameter is not available. The --sharpness switch sets the sharpness of the image data. Valid options are the numbers from -2 to 2, with -2 meaning "De- focus", -1 "Defocus slightly", 0 "Normal", 1 "Sharpen slighly" and 2 "Sharpen". The --gamma-correction switch controls the scanne internal gamma correction. Valid options are "Default", "User defined", "High density printing" "Low density printing" and "High contrast printing". The --color-correction switch controls the scanner internal color correction function. Valid options are "No Correction", "Impact-dot printers", "Thermal printers", "Ink-jet printers" and "CRT monitors". The default is "CRT monitors". The --resolution switch selects the resolution for a scan. Many EPSON scanners will scan in any resulution between the lowest and highest possible value. The list reported by the scanner can be displayed using the "--help -d epkowa" parameters to scanim- age. The --mirror option controls the way the image is scanned. By reading the image data from right to left the image is mirored. Valid options are "yes" and "no". The default is "no". The --speed option can improve the scan speed in monochrome mode. Valid options are "yes" or "no", the "yes" option will speed up the scan if this option is supported. The --auto-area-segmentation switch turns on the automatic area segmentation for monochrome scans. The scanner will try to de- termine which areas are text and which contain images. The image areas will be halftoned, and the text will be impoved. Valid op- tions are "yes" and "no". The default is "yes". The --gamma-table parameter can be used to download a user de- fined gamma table. The options takes 256 values from the range 0-255. In color mode this option equally affects the red, green, and blue channel. The --red-gamma-table parameter can be used to download a user defined gamma table for the red channel. The valid options are the same as for --gamma-table. The --green-gamma-table parameter can be used to download a user defined gamma table for the green channel. The valid options are the same as for --gamma-table. The --blue-gamma-table parameter can be used to download a user defined gamma table for the blue channel. The valid options are the same as for --gamma-table. The color correction coefficients --cct-1 --cct-2 --cct-3 ... --cct-9 will install color correction coefficients for the user defined color correction. Possible values are in the range -127..127. The --preview option requests a preview scan. The frontend soft- ware automatically selects a low resolution. Valid options are "yes" and "no". The default is "no". The --preview-speed options will increase the scan speed if this is supported by the scanner. Valid options are "yes" and "no", the default is "no". The geometry options -l -t -x -y control the scan area: -l sets the top left x coordinate, -t the top left y coordinate, -x se- lects the width and -y the height of the scan aea. All parame- ters are specified in milimeters. The --quick-format option lets the user select a scan area with predefined sizes. Valid parameters are "CD", "A5 portrait", "A5 landscape", "Letter", "A4" and "max". The default is "max", which selects the largest possible area. The --source option selects the scan source. Valid options de- pend on the installed options. The default is "Flatbed". The --auto-eject option will eject a page after scanning from the document feeder. CONFIGURATION FILE The configuration file /usr/local/etc/sane.d/epkowa.conf specifies the device(s) that the backend will use. The current version only supports one scanner per EPSON backend. Possible connection types are: SCSI This is the default, and if nothing else is specified the back- end software will open a given patch as SCSI device. More infor- mation about valid syntax for SCSI devices can be found in sane- scsi(5). PIP - Parallel Interface The parallel interface can be configured in two ways: An integer number starting at the beginning of a line will be interpreted as the IO address of the parallel port. To make it clearer that a configured IO address is a parallel port the port address can be preceded by the string "PIO". The PIO connection does not use a special device file in the /dev directory. USB A device file that is preceded by the string "USB" is treated as a scanner connected via the Universal Serial Bus. The correct special device file has to be created prior to using it with Sane. See the USB documentation for more information about how to set up the USB subsystem and the required device files. FILES /usr/local/lib/sane/libsane-epkowa.a The static library implementing this backend. /usr/local/lib/sane/libsane-epkowa.so The shared library implementing this backend (present on systems that support dynamic loading). ENVIRONMENT SANE_DEBUG_EPKOWA If the library was compiled with debug support enabled, this en- vironment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity. SANE_EPSON_CMD_LVL This allows to override the function or command level that the backend uses to communicate with the scanner. The function level a scanner supports is determined during the initialization of the device. If the backend does not recognize the function level reported by the scanner it will default to function level B5. Valid function levels are A1, A2, B1, B2, B3, B4, B5, B6, B7, B8 and F5. Use this feature only if you know what you are doing! SEE ALSO sane-scsi(5), scanimage(1), xscanimage(1), xsane(1), sane-epson(5) BUGS When used with "scanimage -T" the backend hangs after sucessfully com- pleting the tests. It is necessary to powercycle the scanner to get the communication between backend and scanner going again. Sometimes the scanner is not initialized correctly. The problem can be resolved by killing the program and restarting it again. UNSUPPORTED DEVICES The backend may be used with EPSON scanners that are not yet listed un- der the list of supported devices. A scanner that is not recognized may default to the function level B3, which means that not all functions that the scanner may be capable of are accessible. If the scanner is not even recognized as an EPSON scanner it is proba- bly because the device name eported by the scanner is not in the cor- rect format. Please send this information to the backend maintainer (email address is in the AUTHORS file).devices.
