6 sane-epson2 - SANE backend for EPSON scanners
7
9 The sane-epson2 library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to Epson flatbed scanners. This library
11 supports a similar set of scanners as the sane-epson driver but was
12 developed to support a wider range of connections to the scanner;
13 include network access.
14 Because sane-epson and sane-epson2 drivers support many of the same
16 devices, if one driver gives you problems you may try disabling it to
17 try the other. This can be done by removing the driver name from the
18 dll.conf or perhaps by commenting out the options in epson.conf or
19 epson2.conf.
20 At present, the following scanners are known to work with this backend:

90 The options the backend supports can either be selected through command
91 line options to programs like scanimage or through GUI elements in pro‐
92 grams like xscanimage or xsane.
93 Valid command line options and their syntax can be listed by using
95 scanimage --help -d epson2
96 Not all devices support all options.
97 Scan Mode
99 The --mode switch selects the basic mode of operation of the
100 scanner. Valid choices are Binary, Gray and Color. The Binary
101 mode is black and white only, Gray will produce 256 levels of
102 gray or more depending on the scanner and Color means 24 bit
103 color mode or more depending on the scanner. Some scanners will
104 internally use 36 bit color, their external interface however
105 may only support 24 bits.
106 The --depth option selects the bit depth the scanner is using.
108 This option is only available for scanners that support more
109 than one bit depth. Older scanners will always transfer the
110 image in 8bit mode. Newer scanners allow one to select either 8
111 bits, 12 or 14 bits per color channel. For a color scan this
112 means an effective color depth of 36 or 42 bits over all three
113 channels. The valid choices depend on the scanner model.
114 The --halftoning switch selects the mode that is used in Binary
116 mode. Valid options are "None", "Halftone A (Hard Tone)",
117 "Halftone B (Soft Tone)", "Halftone C (Net Screen)", "Dither A
118 (4x4 Bayer)", "Dither B (4x4 Spiral)", "Dither C (4x4 Net
119 Screen)", "Dither D (8x4 Net Screen)", "Text Enhanced Technol‐
120 ogy", "Download pattern A", and "Download pattern B".
121 The --dropout switch selects the so called dropout color. Valid
123 options are None, Red, Green and Blue. The default is None. The
124 dropout color is used for monochrome scanning and selects the
125 color that is not scanned. This can be used to e.g. scan an
126 original with a colored background.
127 The --brightness switch controls the brightness of the scan.
129 Valid options are integer values from -3 to 3. The default is 0.
130 The larger the brightness value, the brighter the image gets. If
131 a user defined table for the gamma correction is selected, the
132 brightness parameter is not available.
133 The --sharpness switch sets the sharpness of the image data.
135 Valid options are integer values from -2 to 2, with -2 meaning
136 "Defocus", -1 "Defocus slightly", 0 "Normal", 1 "Sharpen
137 slightly" and 2 "Sharpen".
138 The --gamma-correction switch controls the scanner's internal
140 gamma correction. Valid options are "Default", "User defined",
141 "High density printing" "Low density printing" and "High con‐
142 trast printing".
143 The --color-correction switch controls the scanner's internal
145 color correction function. Valid options are "No Correction",
146 "Impact-dot printers", "Thermal printers", "Ink-jet printers"
147 and "CRT monitors". The default is "CRT monitors".
148 The --resolution switch selects the resolution for a scan. Some
150 EPSON scanners will scan in any resolution between the lowest
151 and highest possible value. The list reported by the scanner can
152 be displayed using the "--help -d epson" parameters to scanim‐
153 age.
154 The --threshold switch selects the minimum brightness to get a
156 white point.
157 The --mirror option controls the way the image is scanned. By
159 reading the image data from right to left the image is mirrored.
160 Valid options are "yes" and "no". The default is "no".
161 The --auto-area-segmentation switch activates the automatic area
163 segmentation for monochrome scans. The scanner will try to
164 determine which areas are text and which contain images. The
165 image areas will be halftoned, and the text will be improved.
166 Valid options are "yes" and "no". The default is "yes".
167 The --red-gamma-table parameter can be used to download a user
169 defined gamma table for the red channel. The valid options are
170 the same as for --gamma-table.
171 The --green-gamma-table parameter can be used to download a user
173 defined gamma table for the green channel. The valid options are
174 the same as for --gamma-table.
175 The --blue-gamma-table parameter can be used to download a user
177 defined gamma table for the blue channel. The valid options are
178 the same as for --gamma-table.
179 The --wait-for-button parameter can be used to wait until the
181 button on the scanner is pressed to actually start the scan
182 process.
183 The color correction coefficients --cct-1 --cct-2 --cct-3 ...
185 --cct-9 will install color correction coefficients for the user
186 defined color correction. Values are specified as integers in
187 the range -127..127.
188 The --preview option requests a preview scan. The frontend soft‐
190 ware automatically selects a low resolution. Valid options are
191 "yes" and "no". The default is "no".
192 The geometry options -l -t -x -y control the scan area: -l sets
194 the top left x coordinate, -t the top left y coordinate, -x
195 selects the width and -y the height of the scan area. All param‐
196 eters are specified in millimeters.
197 The --source option selects the scan source. Valid options
199 depend on the installed options. The default is "Flatbed".
200 The --auto-eject option will eject a page after scanning from
202 the document feeder.
203 The --film-type option will select the film type for scans with
205 the transparency unit. This option is only activated if the TPU
206 is selected as scan source. Valid options are "Negative Film"
207 and "Positive Film".
208 The --focus-position option selects the focus position for all
210 scans. Valid options are "Focus 2.5mm above glass" and "Focus on
211 glass". The focus on the 2.5mm point above the glass is neces‐
212 sary for scans with the transparency unit, so that the scanner
213 can focus on the film if one of the film holders is used. This
214 option is only functional for selected scanners, all other scan‐
215 ners will ignore this option.
216 The --bay option selects which bay to scan
218 The --eject option ejects the sheet in the ADF.
220 The --adf-mode option select the ADF mode (simplex/duplex).
222
225 The configuration file /etc/sane.d/epson2.conf specifies the device(s)
226 that the backend will use. Possible connection types are:
227 SCSI This is the default, and if nothing else is specified the back‐
229 end software will open a given path as SCSI device. More infor‐
230 mation about valid syntax for SCSI devices can be found in
231 sane-scsi(5).
232 Usually SCSI scanners are configured with a line "scsi EPSON" in
233 this file. In some cases it may be necessary to only use the
234 string "scsi" (e.g. for the GT-6500).
235 PIO - Parallel Interface
237 The parallel interface can be configured in two ways: An integer
238 value starting at the beginning of a line will be interpreted as
239 the IO address of the parallel port. To make it clearer that a
240 configured IO address is a parallel port the port address can be
241 preceded by the string "PIO". The PIO connection does not use a
242 special device file in the /dev directory. The IO address can be
243 specified in hex mode (prefixed with "0x").
244 USB For USB scanners not automatically detect, their VENDOR and
246 PRODUCT ID can be specified manually in the config file. More
247 information about valid syntax for USB devices can be found in
248 sane-usb(5).
249 Network
251 Network scanners can be auto-discovered if autodiscovery is
252 specified after net keyword. An IP address to connect to can
253 also be used.
254
256 /usr/lib64/sane/libsane-epson2.a
257 The static library implementing this backend.
258 /usr/lib64/sane/libsane-epson2.so
260 The shared library implementing this backend (present on systems
261 that support dynamic loading).
262
264 SANE_DEBUG_EPSON2
265 If the library was compiled with debug support enabled, this
266 environment variable controls the debug level for this backend.
267 E.g., a value of 128 requests all debug output to be printed.
268 Smaller levels reduce verbosity.
269 SANE_DEBUG_EPSON2_SCSI
271 If the library was compiled with debug support enabled, this
272 environment variable controls the SCSI related debug level for
273 this backend. Only a value of 2 is supported.
274 SANE_DEBUG_EPSON2_NET
276 If the library was compiled with debug support enabled, this
277 environment variable controls the network related debug level
278 for this backend. E.g., a value of 128 requests all debug out‐
279 put to be printed. Smaller levels reduce verbosity.
280 SANE_EPSON2_CMD_LVL
282 This allows one to override the function or command level that
283 the backend uses to communicate with the scanner. The function
284 level a scanner supports is determined during the initialization
285 of the device. If the backend does not recognize the function
286 level reported by the scanner it will default to function level
287 B3. Valid function levels are A1, A2, B1, B2, B3, B4, B5, B6,
288 B7, B8, D1 and F5. Use this feature only if you know what you
289 are doing!
290
293 sane-scsi(5), sane-usb(5), scanimage(1), xscanimage(1), xsane(1)
294
297 None :-) At least none are currently known.
298
301 The backend may be used with Epson scanners that are not yet listed
302 under the list of supported devices. A scanner that is not recognized
303 may default to the function level B3, which means that not all func‐
304 tions that the scanner may be capable of are accessible.
305 If the scanner is not even recognized as an Epson scanner this is prob‐
307 ably because the device name reported by the scanner is not in the cor‐
308 rect format. Please send this information to the backend maintainer
309 (email address is in the AUTHOR section of this man page or in the
310 AUTHORS file of the SANE distribution).

315 work done by Karl Hienz Kremer in the epson package as well as based on
316 work by Christian Bucher and Kazuhiro Sasayama
