6 sane-pixma - SANE backend for Canon Multi-Function Printers and
7 CanoScan Scanners
8
10 The sane-pixma library implements a SANE (Scanner Access Now Easy)
11 backend that provides access to Canon PIXMA / i-SENSYS / imageCLASS /
12 imageRUNNER multi-function devices (All-in-one printers) and the Canon
13 CanoScan Flatbed/TPU scanners. The backend implements both the USB
14 interface and network interface (using Canon's BJNP and MFNP proto‐
15 cols). The network interface supports scanners over IPv4 as well as
16 IPv6 (MFNP over IPv6 is untested).
17 Currently, the following models work with this backend:

57 The following models are not well tested and/or the scanner sometimes
59 hangs and must be switched off and on.
60 PIXMA MP760, MP770, MP780, MP790
62 The following models may use the same Pixma protocol as those listed
64 above, but have not yet been reported to work (or not). They are
65 declared in the backend so that they get recognized and activated.

90 The following models may use partly the same Pixma protocol as other
92 devices listed above, but may still need some work. They are declared
93 in the backend as experimental and need the environment variable
94 PIXMA_EXPERIMENT=1 to get recognized and activated. Snoop logs are
95 required to further investigate, please contact the sane-devel mailing
96 list.

99 The backend supports:
101 * resolutions of 75, 150, 300, 600, 1200, 2400, 4800, and 9600
103 DPI (some maybe buggy),
104 * color and grayscale mode, as well as lineart on certain mod‐
105 els,
106 * a custom gamma table,
107 * Automatic Document Feeder, Simplex and Duplex.
108 * Transparency Unit, 24 or 48 bits depth. Infrared channel on
109 certain models.
110 The device name for USB devices is in the form pixma:xxxxyyyy_zzzzz
112 where x, y and z are vendor ID, product ID and serial number respec‐
113 tively.
114 Example: pixma:04A91709_123456 is a MP150.
116 Device names for BJNP/MFNP devices is in the form pixma:aaaa_bbbbb
118 where aaaa is the scanners model and bbbb is the hostname or ip-adress.
119 Example: pixma:MF4800_192.168.1.45 is a MF4800 Series multi-function
121 peripheral.
122 This backend, based on cloning original Canon drivers protocols, is in
124 a production stage. Designed has been carried out without any applica‐
125 ble manufacturer documentation, probably never available. However, we
126 have tested it as well as we could, but it may not work in all situa‐
127 tions. You will find an up-to-date status at the project homepage. (See
128 below). Users feedback is essential to help improve features and per‐
129 formances.
130
132 Besides "well-known" options (e.g. resolution, mode etc.) backend also
133 provides the following options, i.e. the options might change in the
134 future.
135 The button status can be polled i.e. with scanimage -A.
136 Button scan is disabled on MAC OS X due to darwin libusb not handling
137 timeouts in usb interrupt reads, but may work when using the network
138 protocol.
139 adf-wait
141 This option enables and sets the time in seconds waiting for a
142 document inserted into the Automatic Document Feeder. The maxi‐
143 mum allowed waiting time is 3600 sec (= 1 hour).
144 button-controlled
146 This option can be used by applications (like scanadf(1) and
147 scanimage(1)) in batch mode, for example when you want to scan
148 many photos or multiple-page documents. If it is enabled (i.e.
149 is set to true or yes), the backend waits before every scan
150 until the user presses the "SCAN" button (for MP150) or the
151 color-scan button (for other models). Just put the first page in
152 the scanner, press the button, then the next page, press the
153 button and so on. When you finished, press the gray-scan button.
154 (For MP150 you have to stop the frontend by pressing Ctrl-C for
155 example.)
156 button-update (deprecated)
158 (write only) In the past this option was required to be set to
159 force reading of the button status for button-1 and button-2.
160 The sane-pixma backend no longer requires this option to be
161 used: if no fresh data is available, it will be now requested
162 automatically from the scanner. This option is left for backward
163 compatibility reasons.
164 button-1 button-2
166 (read only) These options will return the value of the respec‐
167 tive buttons. value 0 means that the button was not pressed, 1
168 is returned when the button was pressed. Some scanners with more
169 than two buttons send the button number as target.
170 original
172 (read only) Returns the value of the type or size of original to
173 be scanned if the scanner provides that data. Known values of
174 type: 1 = document, 2 = photo, 5 = film. Known values of size: 1
175 = A4, 2 = Letter, 8 = 10x15, 9 = 13x18, b = auto. Not all scan‐
176 ners can provide this data.
177 target (read only) Returns the value of the target of the scan opera‐
179 tion if the scanner provides that data. The values depend on the
180 scanner type. Known values: 1 = save to disk, 2 = save to pdf, 3
181 = send to email, 4 = send to application or 1 = JPEG, 2 = TIFF,
182 3 = PDF, 4 = Compact PDF. For some scanners this value is equiv‐
183 alent to the number of the pressed button. Not all scanners can
184 provide this data.
185 scan-resolution
187 (read only) Returns the resolution of the scan operation if the
188 scanner provides that data. Known values: 1 = 75 dpi, 2 = 150
189 dpi, 3 = 300 dpi, 4 = 600 dpi. Not all scanners can provide this
190 data.
191 document-type
193 (read only) Returns the type of the scanned document if the
194 scanner provides that data. Known values: 1 = Document, 2 =
195 Photo, 3 = Auto scan. Not all scanners can provide this data.
196 adf-status
198 (read only) Returns the status of the document feeder if the
199 scanner provides that data. Known values: 1 = ADF empty, 2 = ADF
200 filled. Not all scanners can provide this data.
201 adf-orientation
203 (read only) Returns the scan orientation of the medium scanned
204 from ADF if the scanner provides that data. Known values: 1 =
205 Portrait, 2 = Landscape. Not all scanners can provide this data.
206
208 /usr/lib64/sane/libsane-pixma.a
209 The static library implementing this backend.
210 /usr/lib64/sane/libsane-pixma.so
212 The shared library implementing this backend (present on systems
213 that support dynamic loading).
214 /etc/sane.d/pixma.conf
216 The backend configuration file (see also description of
217 SANE_CONFIG_DIR below).
218 The file contains an optional list of networked scanners using
220 the BJNP or MFNP protools (See below for datails on networking
221 support for scanners). Normally only scanners that cannot be
222 auto-detected because they are on a different subnet shall be
223 listed here. If you do not use Linux and your OS does not allow
224 enumeration of interfaces (i.e. it does not support the getifad‐
225 drs() qfunction) you also may need to add your scanner here as
226 well.
227 Scanners shall be listed in the configuration file as follows:
229 <method>://<host>[:port][/timeout=<value>]
231 where method indicates the protocol used (bjnp is used for
233 inkjet multi-functionals and mfnp is used for laser multi-func‐
234 tionals).
235 host is the hostname or IP address of the scanner, e.g.
237 bjnp://10.0.1.4 for IPv4,
238 bjnp://[2001:888:118e:18e2:21e:8fff:fe36:b64a] for a literal
239 IPv6-address or bjnp://myscanner.mydomain.org for a hostname.
240 The port number is optional and in normally implied by the
242 method. Port 8610 is the standard port for mfnp, 8612 for bjnp.
243 A scanner specific timeout value for the network protocol can be
245 set using the bjnp-timeout parameter. The value is in ms.
246 Define scanners each on a new line.
248 More globally applicable timeouts can be set using the bjnp-
250 timeout parameter as follows:
251 bjnp-timeout=<value>
253 A timeout defined using bjnp-timeout will apply to the following
255 scanner definitions in the file. If required the bjnp-timeout
256 setting can be defined multiple times, where each setting will
257 apply only to the scanners that follow the setting. The last
258 setting is used for the auto discovered scanners. If not
259 explicitly set, the default 1000ms setting will apply.
260 Setting timeouts should only be required in exceptional cases.
262 If so desired networking can be disabled as follows:
264 - If the first non-commented line contains networking=no
266 all networking will be disabled. This will cause all
267 further statements in the configuration file to be
268 ignored.
269 - A line that contains auto_detection=no will cause auto-
271 detection to be skipped. Explicitly defined network scan‐
272 ners will still be probed.
273
275 USB scanners will be auto-detected and require no configuration.
276
278 The sane-pixma backend supports network scanners using the so called
279 Canon BJNP and MFNP protocols.
280 Canon seems to be dropping support for these protocols in recent scan‐
282 ners. To verify if your scanner supports one of these protocols, check
283 the content of the _scanner._tcp service entry in mDNS/DNS-SD (using
284 for example avahi-discover(1)). If that does not list port 8610 or
285 8612 your scanner probably does not support the mfmp or bjnp protols.
286 Both IPv4 and IPv6 are supported, but IPv6 is as yet untested with
288 MFNP. Please report your results on the mailing list.
289 Configuration is normally not required. The sane-pixma backend will
291 auto-detect your scanner if it is within the same subnet as your com‐
292 puter if your OS does support this.
293 If your scanner can not be auto-detected, you can add it to the
295 sane-pixma configuration file (see above).
296
298 The sane-pixma backend communicates with port 8610 for MFNP or port
299 8612 for BJNP on the scanner. So you will have to allow outgoing traf‐
300 fic TO port 8610 or 8612 on the common subnet for scanning.
301 Scanner detection is slightly more complicated. The sane-pixma backend
303 sends a broadcast on all direct connected subnets it can find (provided
304 your OS allows for enumeration of all network interfaces). The broad‐
305 cast is sent FROM port 8612 TO port 8610 or 8612 on the broadcast
306 address of each interface. The outgoing packets will be allowed by the
307 rule described above.
308 Responses from the scanner are sent back to the computer TO port 8612.
310 Connection tracking however does not see a match as the response does
311 not come from the broadcast address but from the scanners own address.
312 For automatic detection of your scanner, you will therefore have to
313 allow incoming packets TO port 8612 on your computer. This applies to
314 both MFNP and BJNP.
315 So in short: open the firewall for all traffic from your computer to
317 port 8610 (for MFNP) or 8612 (for BJNP) AND to port 8612 (for both BJNP
318 and MFNP) to your computer.
319 With the firewall rules above there is no need to add the scanner to
321 the pixma.conf file, unless the scanner is on a network that is not
322 directly connected to your computer.
323
325 SANE_DEBUG_PIXMA
326 If the library was compiled with debug support enabled, this
327 environment variable controls the debug level for this backend
328 itself. Higher value increases the verbosity and includes the
329 information printed at the lower levels.
330 0 print nothing (default)
331 1 print error and warning messages (recommended)
332 2 print informational messages
333 3 print debug-level messages
334 4 print verbose debug-level messages
335 11 dump USB traffic
336 21 full dump USB traffic
337 SANE_DEBUG_BJNP
339 If the library was compiled with debug support enabled, this
340 environment variable controls the debug level for the BJNP and
341 MFNP network protocols for this backend. Higher value increases
342 the verbosity and includes the information printed at the lower
343 levels.
344 0 print nothing (default)
345 1 Print error and warning messages (recommended)
346 2 Print high level function tracing information
347 3 Print more detailed protocol tracing information
348 4 Print protocol headers
349 5 Print full protocol contents
350 PIXMA_EXPERIMENT
352 Setting to a non-zero value will enable the support for experi‐
353 mental models. You should also set SANE_DEBUG_PIXMA to 11.
354 SANE_CONFIG_DIR
356 This environment variable specifies the list of directories that
357 may contain the configuration file. Under UNIX, the directories
358 are separated by a colon (`:'), under OS/2, they are separated
359 by a semi-colon (`;'). If this variable is not set, the config‐
360 uration file is searched in two default directories: first, the
361 current working directory (".") and then in /etc/sane.d. If the
362 value of the environment variable ends with the directory sepa‐
363 rator character, then the default directories are searched after
364 the explicitly specified directories. For example, setting
365 SANE_CONFIG_DIR to "/tmp/config:" would result in directories
366 tmp/config, ., and /etc/sane.d being searched (in this order).
