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

              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

              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).
