sane-pixma

DESCRIPTION
       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.

              PIXMA E400, E460, E480, E500, E510, E560, E600, E610
              PIXMA MG4100, MG5400, MG5600, MG6500, MG6600, MG7500, MG8100
              PIXMA MP375R, MP493, MP495, MP740
              PIXMA MX320, MX390, MX430, MX450, MX470, MX490, MX710
              imageCLASS MF810/820, MF5630, MF5650, MF5750, MF8030, MF8170c

              i-SENSYS MF210 Series, MF220 Series, MF5880dn, MF5900 Series
              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-
       tively.

       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
       peripheral.

       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-
       formances.

OPTIONS
       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
       protocol.

       button-controlled
              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
              example.)

       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
              reasons.

       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
              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.

       scan-resolution
              (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
              data.

FILES
       /usr/lib/arch_triplet/sane/libsane-pixma.a
              The static library implementing this backend.

       /usr/lib/arch_triplet/sane/libsane-pixma.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

       /etc/sane.d/pixma.conf
              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:

              <method>://<host>[:port]

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

              host is  the  hostname  or  IP  address  of  the  scanner,  e.g.
              bjnp://10.0.1.4                     for                    IPv4,
              bjnp://[2001:888:118e:18e2:21e:8fff:fe36:b64a]  for  a   literal
              IPv6-address or bjnp://myscanner.mydomain.org 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 SUPPORT
       USB scanners will be auto-detected and require no configuration.

NETWORKING SUPPORT
       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
       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.

ENVIRONMENT
       SANE_DEBUG_PIXMA
              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

       SANE_DEBUG_BJNP
              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
              levels.
              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

       PIXMA_EXPERIMENT
              Setting  to a non-zero value will enable the support for experi-
              mental models.  You should also set SANE_DEBUG_PIXMA to 11.
              "tmp/config", ".", and "/etc/sane.d"  being  searched  (in  this
              order).
