       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  proto‐
       cols).  The  network  interface  supports scanners over IPv4 as well as
       IPv6 (MFNP over IPv6 is untested).

       Currently, the following models work with this backend:

              PIXMA MG2100, MG2200, MG2400, MG2500, MG2900, MG3100, MG3200

       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 mod‐
              * 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  respec‐

       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  applica‐
       ble  manufacturer  documentation, probably never available. However, we
       have tested it as well as we could, but it may not work in  all  situa‐
       tions. You will find an up-to-date status at the project homepage. (See
       below).  Users feedback is essential to help improve features and  per‐


       Besides "well-known" options (e.g. resolution, mode etc.) pixma backend
       also provides the following options, 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  enables and sets the time in seconds waiting for a
              document inserted into the Automatic Document Feeder.  The maxi‐
              mum allowed waiting time is 3600 sec (= 1 hour).

              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 respec‐
              tive 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 target.

              (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 scan‐
              ners can provide this data.

       target (read only) Returns the value of the target of the  scan  opera‐
              tion 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 equiv‐
              alent  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  file contains an optional list of
              networked scanners. Normally only scanners that cannot 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 also may need
              to add your scanner here as well.

              Scanners shall be listed in the configuraton file as follows:


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

              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.

              A scanner specific timeout value for the network protocol can be
              set using the bjnp-timeout parameter. The value is in ms.

              Define scanners each on a new line.

              More  globally  applicable  tinmeouts can be set using the bjnp-
              timeout parameter as folllows:


              A timeout defined using bjnp-timeout will apply to the following
              scanner  definitions  in  the file. If required the bjnp-timeout
              setting can be defined multiple times, where  each  settng  will
              apply  only  to  the  scanners that follow the setting. The last
              setting is used  for  the  auto  discovered  scanners.   If  not
              explicitely set,  the default 1000ms setting will apply.

              Setting timeouts should only be required in exceptional cases.


       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  traf‐
       fic 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  experi‐
              mental models.  You should also set SANE_DEBUG_PIXMA to 11.

              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 config‐
              uration  file is searched in two default directories: first, the
              current    working    directory    (".")     and     then     in
              /usr/local/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 directo‐
              ries.  For example, setting  SANE_CONFIG_DIR  to  "/tmp/config:"
              would    result    in   directories   "tmp/config",   ".",   and
              "/usr/local/etc/sane.d" being searched (in this order).
