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 MG2100, MG2200, MG2400, MG2500, MG2900, MG3100, MG3200
              PIXMA MG3500, MG4200, MG5100, MG5200, MG5300, MG5500, MG6100
              PIXMA MG6200, MG6300, MG6400, MG7100, MG8200
              PIXMA MP140, MP150, MP160, MP170, MP180, MP190
              PIXMA MP210, MP220, MP230, MP240, MP250, MP260, MP270, MP280

              imageCLASS MF3110, MF3240, MF4010, MF4018
              imageCLASS MF4120, MF4122, MF4140, MF4150
              imageCLASS MF4270, MF4350d, MF4370dn, MF4380dn
              imageCLASS MF4410, MF4430, MF4570dw, MF4660, MF4690
              imageCLASS MF5730, MF5770, MF6550, D420, D480, D530
              i-SENSYS MF3010, MF4320d, MF4330d, MF4500 Series
              i-SENSYS MF4700 Series, MF4800 Series, MF8200C Series
              i-SENSYS MF8300 Series
              imageRUNNER 1020/1024/1025
              CanoScan 8800F, 9000F, 9000F Mark II

       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
              imageRUNNER 1133
              i-SENSYS MF210 Series, MF220 Series, MF5880dn, MF5900 Series
              i-SENSYS MF6100 Series, MF6680dn, MF8500C Series
              MAXIFY MB2000, MB2300, MB5000, MB5300

       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.) 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 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 = 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.

       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-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.

              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 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).

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  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 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.  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).
