NAME
       sane-pixma - SANE backend for Canon PIXMA MP series


DESCRIPTION
       The  sane-pixma  library  implements  a  SANE (Scanner Access Now Easy)
       backend that provides access  to  Canon  PIXMA  multi-function  devices
       (All-in-one  printers).   The backend implements both USB interface and
       Network LAN interface using  Canon’s  BJNP  protocol.   Currently,  the
       following models work with this backend:

              PIXMA MP140, MP150, MP160, MP170, MP180, MP190
              PIXMA MP210, MP220, MP240
              PIXMA MP450, MP460, MP470, MP480
              PIXMA MP500, MP510, MP520, MP530, MP540
              PIXMA MP600, MP600R, MP610, MP620, MP630, MP710
              PIXMA MP800, MP800R, MP810, MP830, MP960, MP970, MP980
              PIXMA MX300, MX310, MX700, MX850, MX7600
              MultiPASS MP700, PIXMA MP750 (no grayscale)
              ImageCLASS MF4010, MF4018, MF4120, MF4122, MF4140, MF4150
              ImageCLASS MF4270

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

              SmartBase MP360, MP370, MP390
              MultiPASS MP730, PIXMA MP760, PIXMA MP780

       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-dev mailing list welcome.

              PIXMA MP740
              PIXMA MP260
              ImageCLASS MF3110, MF3240
              ImageCLASS MF5630, MF5650, MF5730, MF5750, MF5770, MF8170c

       The backend supports
       *  resolutions  at  75,150,300,600,1200,2400  and  4800 DPI (some maybe
       buggy),
       * color and grayscale mode,
       * a custom gamma table,
       * Automatic Document Feeder (Duplex for some models).
       * Transparency Unit, 24 or 48 bits depth.

       The device name 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.

       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
       every 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.
       Button scan is disabled on MAC OS X due to darwin libusb  not  handling
       timeouts in usb interrupt reads.

       button-controlled
              This  option  can  be  used  in  combination with 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 button-1 button-2
              These options are interesting for developers.  To  check  button
              status:  (1)  set button-1 and button-2 to zero, (2) set button-
              update (Its type is SANE_TYPE_BUTTON.),  (3)  get  button-1  and
              button-2.   If  the result is not zero, the corresponding button
              was pressed.


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

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


ENVIRONMENT
       SANE_DEBUG_PIXMA
              If  the  library  was  compiled with debug support enabled, this
              environment variable controls the debug level for this  backend.
              Higher value increases the verbosity.

              0  print nothing (default)
              1  print error and warning messages (recommended)
              2  print informational messages
              3  print debug-level messages
              11 dump USB traffics
              21 full dump USB traffics

       PIXMA_EXPERIMENT
              Setting  to  a  non-zero  value  will  enable  the  support  for
              experimental models.  You should also  set  SANE_DEBUG_PIXMA  to
              10.

       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.
