NAME

6       sane-pixma  -  SANE  backend  for  Canon  Multi-Function  Printers  and
7       CanoScan Scanners
8

DESCRIPTION

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 in‐
14       terface and network interface (using Canon's BJNP and MFNP  protocols).
15       The network interface supports scanners over IPv4 as well as IPv6 (MFNP
16       over IPv6 is untested).
17
18       Currently, the following models work with this backend:
19
20              PIXMA E410, E510
21              PIXMA G2000, G2010, G2100, G4000, G4511

58       The following models are not well tested and/or the  scanner  sometimes
59       hangs and must be switched off and on.

63       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  de‐
65       clared in the backend so that they get recognized and activated.  Feed‐
66       back in the sane-devel mailing list welcome.

91       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  re‐
95       quired  to  further  investigate, please contact the sane-devel mailing
96       list.

99
100       The backend supports:
101
102              * 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
111       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
115       Example: pixma:04A91709_123456 is a MP150.
116
117       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
120       Example: pixma:MF4800_192.168.1.45 is a  MF4800  Series  multi-function
121       peripheral.
122
123       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.

OPTIONS

132       Besides  "well-known"  options (e.g. resolution, mode etc.)  sane-pixma
133       backend also provides the following options,  i.e.  the  options  might
134       change in the 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
140       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
145       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  un‐
150              til the user presses the "SCAN" button (for MP150) or the color-
151              scan button (for other models). Just put the first page  in  the
152              scanner,  press the button, then the next page, press the button
153              and so on. When you finished, press the gray-scan  button.  (For
154              MP150 you have to stop the frontend by pressing Ctrl-C for exam‐
155              ple.)
156
157       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
165       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
171       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
178       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
186       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
192       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
197       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
202       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.

FILES

208       /usr/lib64/sane/libsane-pixma.a
209              The static library implementing this backend.
210
211       /usr/lib64/sane/libsane-pixma.so
212              The shared library implementing this backend (present on systems
213              that support dynamic loading).
214
215       /etc/sane.d/pixma.conf
216              The  backend  configuration  file  (see  also   description   of
217              SANE_CONFIG_DIR below).
218
219              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
228              Scanners shall be listed in the configuration file as follows:
229
230                     <method>://<host>[:port][/timeout=<value>]
231
232              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
236              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
241              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
244              A scanner specific timeout value for the network protocol can be
245              set using the bjnp-timeout parameter. The value is in ms.
246
247              Define scanners each on a new line.
248
249              More  globally  applicable  timeouts  can be set using the bjnp-
250              timeout parameter as follows:
251
252                     bjnp-timeout=<value>
253
254              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  ex‐
259              plicitly set, the default 1000ms setting will apply.
260
261              Setting timeouts should only be required in exceptional cases.
262
263       If so desired networking can be disabled as follows:
264
265              -      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 ig‐
268                     nored.
269
270              -      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

USB SUPPORT

275       USB scanners will be auto-detected and require no configuration.
276

NETWORKING SUPPORT

278       The sane-pixma backend supports network scanners using  the  so  called
279       Canon BJNP and MFNP protocols.
280
281       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
287       Both  IPv4  and  IPv6  are  supported, but IPv6 is as yet untested with
288       MFNP. Please report your results on the mailing list.
289
290       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
294       If your scanner can not  be  auto-detected,  you  can  add  it  to  the
295       sane-pixma configuration file (see above).
296

FIREWALLING FOR NETWORKED SCANNERS

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
302       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  ad‐
306       dress  of  each interface.  The outgoing packets will be allowed by the
307       rule described above.
308
309       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 al‐
313       low incoming packets TO port 8612 on your  computer.  This  applies  to
314       both MFNP and BJNP.
315
316       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
320       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 di‐
322       rectly connected to your computer.

ENVIRONMENT

325       SANE_DEBUG_PIXMA
326              If the library was compiled with debug support enabled, this en‐
327              vironment variable controls the debug level for this backend it‐
328              self.  Higher value increases the verbosity and includes the in‐
329              formation 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
338       SANE_DEBUG_BJNP
339              If the library was compiled with debug support enabled, this en‐
340              vironment  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
351       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
355       SANE_CONFIG_DIR
356              This environment variable specifies the list of directories that
357              may contain the configuration file.  On *NIX systems, the direc‐
358              tories are separated by a colon (`:'), under OS/2, they are sep‐
359              arated by a semi-colon (`;').  If this variable is not set,  the
360              configuration  file  is  searched  in  two  default directories:
361              first,  the  current  working  directory  (".")  and   then   in
362              /etc/sane.d.  If the value of the environment variable ends with
363              the directory separator character, then the default  directories
364              are  searched  after  the explicitly specified directories.  For
365              example, setting SANE_CONFIG_DIR to "/tmp/config:" would  result
366              in directories tmp/config, ., and /etc/sane.d being searched (in
367              this order).
