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


   The sane-pixma library implements a  SANE  (Scanner  Access  Now  Easy)
   backend  that  provides access to Canon PIXMA / i-SENSYS / imageCLASS /
   imageRUNNER multi-function devices (All-in-one printers) and the  Canon
   CanoScan  Flatbed/TPU  scanners.   The  backend implements both the USB
   interface  and  network  interface  (using  Canon's   BJNP   and   MFNP
   protocols).  The  network interface supports scanners over IPv4 as well
   as IPv6 (MFNP over IPv6 is untested).

   Currently, the following models work with this backend:

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

          PIXMA MP760, MP770, MP780, MP790

   The  following  models  may use the same Pixma protocol as those listed
   above, but have not yet been  reported  to  work  (or  not).  They  are
   declared  in  the  backend  so  that they get recognized and activated.
   Feedback in the sane-devel mailing list welcome.

   The backend supports:

          * resolutions of 75, 150, 300, 600, 1200, 2400, 4800,  and  9600
          DPI (some maybe buggy),
          *  color  and  grayscale  mode,  as  well  as lineart on certain
          * a custom gamma table,
          * Automatic Document Feeder, Simplex and Duplex.
          * Transparency Unit, 24 or 48 bits depth.  Infrared  channel  on
          certain models.

   The  device  name  for  USB devices is in the form pixma:xxxxyyyy_zzzzz
   where x,  y  and  z  are  vendor  ID,  product  ID  and  serial  number

   Example: pixma:04A91709_123456 is a MP150.

   Device  names  for  BJNP/MFNP  devices  is in the form pixma:aaaa_bbbbb
   where aaaa is the scanners model and bbbb is the hostname or ip-adress.

   Example: pixma:MF4800_192.168.1.45 is a  MF4800  Series  multi-function

   This  backend, based on cloning original Canon drivers protocols, is in
   a  production  stage.  Designed  has  been  carried  out  without   any
   applicable   manufacturer   documentation,  probably  never  available.
   However, we have tested it as well as we could, but it may not work  in
   all  situations.  You  will  find  an  up-to-date status at the project
   homepage. (See below).  Users feedback is  essential  to  help  improve
   features and performances.


   Besides "well-known" options (e.g. resolution, mode etc.) pixma backend
   also provides the following  options  for  button  handling,  i.e.  the
   options might change in the future.
   The button status can be polled i.e. with 'scanimage -A'.
   Button  scan  is disabled on MAC OS X due to darwin libusb not handling
   timeouts in usb interrupt reads, but may work when  using  the  network

          This  option  can  be  used by applications (like scanadf(1) and
          scanimage(1)) in batch mode, for example when you want  to  scan
          many  photos  or multiple-page documents. If it is enabled (i.e.
          is set to true or yes), the  backend  waits  before  every  scan
          until  the  user  presses  the  "SCAN" button (for MP150) or the
          color-scan button (for other models). Just put the first page in
          the  scanner,  press  the  button, then the next page, press the
          button and so on. When you finished, press the gray-scan button.
          (For  MP150 you have to stop the frontend by pressing Ctrl-C for

   button-update (deprecated)
          (write only) In the past this option was required to be  set  to
          force  reading  of  the button status for button-1 and button-2.
          The sane-pixma no longer requires this option to be used: if  no
          fresh  data is available, it will be now requested automatically
          from the scanner. This option is left for backward compatibility

   button-1 button-2
          (read   only)  These  options  will  return  the  value  of  the
          respective buttons.  value 0  means  that  the  button  was  not
          pressed,  1  is  returned  when  the  button  was  pressed. Some
          scanners with more than two buttons send the  button  number  as

          (read only) Returns the value of the type or size of original to
          be scanned if the scanner provides that data.  Known  values  of
          type:  1 = document, 2 = foto, 5 = film. Known values of size: 1
          = A4, 2 = Letter, 8 = 10x15, 9 =  13x18,  b  =  auto.   Not  all
          scanners can provide this data.

   target (read  only)  Returns  the  value  of  the  target  of  the scan
          operation if the scanner provides that data. The  values  depend
          on the scanner type. Known values: 1 = save to disk, 2 = save to
          pdf, 3 = send to email, 4 = send to application or 1 = JPEG, 2 =
          TIFF,  3 = PDF, 4 = Compact PDF. For some scanners this value is
          equivalent to the number of the pressed button. Not all scanners
          can provide this data.

          (read  only) Returns the resolution of the scan operation if the
          scanner provides that data. Known values: 1 = 75 dpi,  2  =  150
          dpi, 3 = 300 dpi, 4 = 600 dpi. Not all scanners can provide this


          The static library implementing this backend.

          The shared library implementing this backend (present on systems
          that support dynamic loading).

          The   backend   configuration  file  (see  also  description  of
          SANE_CONFIG_DIR below). The files contains an optional  list  of
          networked scanners. Normally only scanners that can not be auto-
          detected because they are on a different subnet shall be  listed
          here.  If your OS does not allow enumeration of interfaces (i.e.
          it does not support the getifaddrs() function) you may  need  to
          add your scanner here as well.

   Scanners shall be listed as:


          where  method  indicates  the  protocol  used  (bjnp is used for
          inkjet multi-functionals and  mfnp  is  used  for  laser  multi-

          host  is  the  hostname  or  IP  address  of  the  scanner, e.g.
          bjnp://                    for                     IPv4,
          bjnp://[2001:888:118e:18e2:21e:8fff:fe36:b64a]   for  a  literal
          IPv6-address or bjnp:// for a hostname.

          The port number is optional  and  in  normally  implied  by  the
          method.  Port 8610 is the standard port for mfnp, 8612 for bjnp.

          Define each scanner on a new line.


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


   The  pixma  backend supports network scanners using the so called Canon
   BJNP protocol and MFNP protocol. Both IPv4 and IPv6 are supported,  but
   IPv6  is  as  yet untested with MFNP. Please report your results on the
   mailing list.

   Configuration is normally not required.  The pixma backend  will  auto-
   detect your scanner if it is within the same subnet as your computer if
   your OS does support this.

   If your scanner can not be auto-detected, you can add it to  the  pixma
   configuration file (see above).


   The  sane  pixma  backend  communicates with port 8610 for MFNP or port
   8612 for BJNP on the scanner.  So  you  will  have  to  allow  outgoing
   traffic TO port 8610 or 8612 on the common subnet for scanning.

   Scanner detection is slightly more complicated. The pixma backend sends
   a broadcast on all direct connected subnets it can find (provided  your
   OS  allows for enumeration of all netowrk interfaces). The broadcast is
   sent FROM port 8612 TO port 8610 or 8612 on the  broadcast  address  of
   each  interface.   The  outgoing  packets  will  be allowed by the rule
   described above.

   Responses from the scanner are sent back to the computer TO port  8612.
   Connection  tracking  however does not see a match as the response does
   not come from the broadcast address but from the scanners own  address.
   For  automatic  detection  of  your scanner, you will therefore have to
   allow incoming packets TO port 8612 on your computer. This  applies  to
   both MFNP and BJNP.

   So  in  short:  open the firewall for all traffic from your computer to
   port 8610 (for MFNP) or 8612 (for BJNP) AND to port 8612 (for both BJNP
   and MFNP) to your computer.

   With  the  firewall  rules above there is no need to add the scanner to
   the pixma.conf file, unless the scanner is on a  network  that  is  not
   directly connected to your computer.


          If  the  library  was  compiled with debug support enabled, this
          environment variable controls the debug level for  this  backend
          itself.  Higher  value  increases the verbosity and includes the
          information printed at the lower levels.
          0  print nothing (default)
          1  print error and warning messages (recommended)
          2  print informational messages
          3  print debug-level messages
          4  print verbose debug-level messages
          11 dump USB traffic
          21 full dump USB traffic

          If the library was compiled with  debug  support  enabled,  this
          environment  variable  controls the debug level for the BJNP and
          MFNP network protocols for this backend. Higher value  increases
          the  verbosity and includes the information printed at the lower
          0 print nothing (default)
          1 Print error and warning messages (recommended)
          2 Print high level function tracing information
          3 Print more detailed protocol tracing information
          4 Print protocol headers
          5 Print full protocol contents

          Setting  to  a  non-zero  value  will  enable  the  support  for
          experimental  models.   You  should also set SANE_DEBUG_PIXMA to

          This environment variable specifies the list of directories that
          may contain the configuration file.  Under UNIX, the directories
          are separated by a colon (`:'), under OS/2, they  are  separated
          by  a  semi-colon  (`;').   If  this  variable  is  not set, the
          configuration file  is  searched  in  two  default  directories:
          first,   the   current  working  directory  (".")  and  then  in
          /etc/sane.d.  If the value of the environment variable ends with
          the  directory separator character, then the default directories
          are searched after the explicitly  specified  directories.   For
          example,  setting SANE_CONFIG_DIR to "/tmp/config:" would result
          in  directories  "tmp/config",  ".",  and  "/etc/sane.d"   being
          searched (in this order).
