NAME

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


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 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:



              PIXMA E410, E510, E4500
              PIXMA G600, G2000, G2010, G2100, G4000, G4511

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

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

              -- none --

       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 models,
              * 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 respectively.

       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 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.


OPTIONS

       Besides "well-known" options (e.g. resolution, mode etc.)  sane-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
       protocol.

       adf-wait
              This option enables and sets the time in seconds waiting for a
              document inserted into the Automatic Document Feeder.  The maximum
              allowed waiting time is 3600 sec (= 1 hour).

       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 backend 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 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 target.

       original
              (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 = photo, 5 = film. Known values of size: 1 =
              A4, 2 = Letter, 8 = 10x15, 9 = 1318, 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.

       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.

       document-type
              (read only) Returns the type of the scanned document if the
              scanner provides that data. Known values: 1 = Document, 2 = Photo,
              3 = Auto scan. Not all scanners can provide this data.

       adf-status
              (read only) Returns the status of the document feeder if the
              scanner provides that data. Known values: 1 = ADF empty, 2 = ADF
              filled. Not all scanners can provide this data.

       adf-orientation
              (read only) Returns the scan orientation of the medium scanned
              from ADF if the scanner provides that data. Known values: 1 =
              Portrait, 2 = Landscape. Not all scanners can provide this data.


FILES

       /opt/local/lib/sane/libsane-pixma.a
              The static library implementing this backend.

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

       /opt/local/etc/sane.d/pixma.conf
              The backend configuration file (see also description of
              SANE_CONFIG_DIR below).

              The file contains an optional list of networked scanners using the
              BJNP or MFNP protools (See below for datails on networking support
              for scanners). Normally only scanners that cannot be auto-detected
              because they are on a different subnet shall be listed here. If
              you do not use Linux and your OS does not allow enumeration of
              interfaces (i.e. it does not support the getifaddrs() qfunction)
              you also may need to add your scanner here as well.

              Scanners shall be listed in the configuration file as follows:

                     <method>://<host>[:port][/timeout=<value>]

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

              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.

              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 timeouts can be set using the bjnp-
              timeout parameter as follows:

                     bjnp-timeout=<value>

              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 setting will
              apply only to the scanners that follow the setting. The last
              setting is used for the auto discovered scanners.  If not
              explicitly set, the default 1000ms setting will apply.

              Setting timeouts should only be required in exceptional cases.

       If so desired networking can be disabled as follows:

              -      If the first non-commented line contains networking=no all
                     networking will be disabled.  This will cause all further
                     statements in the configuration file to be ignored.

              -      A line that contains auto_detection=no will cause auto-
                     detection to be skipped. Explicitly defined network
                     scanners will still be probed.


USB SUPPORT

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


NETWORKING SUPPORT

       The sane-pixma backend supports network scanners using the so called
       Canon BJNP and MFNP protocols.

       Canon seems to be dropping support for these protocols in recent
       scanners.  To verify if your scanner supports one of these protocols,
       check the content of the _scanner._tcp service entry in mDNS/DNS-SD
       (using for example avahi-discover(1)).  If that does not list port 8610
       or 8612 your scanner probably does not support the mfmp or bjnp protols.

       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 sane-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
       sane-pixma configuration file (see above).


FIREWALLING FOR NETWORKED SCANNERS

       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 sane-pixma backend
       sends a broadcast on all direct connected subnets it can find (provided
       your OS allows for enumeration of all network 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
              experimental models.  You should also set SANE_DEBUG_PIXMA to 11.

       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  On *NIX systems, 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
              /opt/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
              directories.  For example, setting SANE_CONFIG_DIR to
              "/tmp/config:" would result in directories tmp/config, ., and
              /opt/local/etc/sane.d being searched (in this order).

       In case of trouble with a recent Pixma model, try the latest code for the
       sane-pixma backend, available in the Sane git repository at:
       https://gitlab.com/sane-project/backends.git

       You can also post into the Sane-devel mailing list for support.

       We would like to thank all testers and helpers. Without them we could not
       be able to write subdrivers for models we don't have. See also the
       project homepage.
