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 inter
   face 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, G2030, G2070, G2100, G3030, G3070, G4000, G4070, G4511

   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. Design 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 en
          abled (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 op
          tion 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 scan
          ners, 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 = 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.

   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  pro
          vide this data.

FILES

   /usr/lib/x86_64-linux-gnu/sane/libsane-pixma.a
          The static library implementing this backend.

   /usr/lib/x86_64-linux-gnu/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 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() function) 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>]

          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://myscan
                 ner.mydomain.org for a hostname.

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

          timeout
                 scanner-specific timeout value for the network protocol. The value is in ms.

          Define each scanner each on a separate 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 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:

          networking=no
                 If the first non-commented line contains this entry all networking will be disabled.  All further statements in the configuration file will be ignored.

          auto_detection=no
                 This line 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 in
          cludes 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 experimental support for further 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 direc
          tory (".") 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 or
          der).
