La pagina de SANE (http://www.sane-project.org/) sinteticamente dice:

Backends included in the CVS repository - see SANE CVS Repository
pixma 	0.14.5 	Canon 	PIXMA MP140 	USB 	0x04a9/0x172b 	good 	All

Cuando vas a la pagina del manual (link sane-pixma), dice:

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).  Currently, the following models work
with this
       backend:

              PIXMA MP150, MP160, MP170, MP180, MP450, MP460
              PIXMA MP500, MP510, MP530, MP600, MP600R
              PIXMA MP800, MP800R, MP810, MP830, MP960
              MultiPASS MP700, PIXMA MP750 (no grayscale)

       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 backend supports
       * resolutions at 75,150,300,600,1200 and 2400 DPI (still buggy),
       * color and grayscale mode,
       * a custom gamma table and
       * automatic document feeder (only single side).

       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 is in alpha stage and will stay in this stage until
we get
       the programming manual for the hardware. Although we have tested
it  as
       good  as  we could, it will not work in every situations. You
will find
       an up-to-date status at the project homepage. (See below)



OPTIONS

       Besides "well-known" options (e.g. resolution, mode etc.) pixma
backend
       also  provides  the following experimental options for button
handling,
       i.e. the options might change in the future.

       button-controlled
              This option can be used in combination with scanadf(1) and
scan-
              image(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
scan-
              ner, 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
              10 dump USB traffics

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

Me llama la atencion que el modelo que tenes no figura explicitamente en
la lista, si bien sale como dispositivo soportado, con lo cual se me
ocurre que algun driver de otro modelo (como los que figura en la pagina
del manual) seria el equivalente (el MP150 quizas ?).

De hecho, debajo del primer cuadro aparece esta aclaracion que si es
especifica sobre ese modelo MP140:

Backend 	Version 	Supported Devices 	Manual Page
Manufacturer 	Model 	Interface 	USB id 	Status 	Comment
Backends neither included in the current tarball nor the CVS repository
canon_mfp 	*none* 	Canon 	MP140 	USB 	0x04a9/0x172b 	untested 	No report
yet.

Con lo cual tengo mis reservas de que funcione como MP140.
