NAME
sane-pixma - SANE backend for Canon PIXMA Multi-Functions Printers
MP, MX, ImageCLASS and I-SENSYS 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, MP250, MP260, MP270
PIXMA MP450, MP460, MP470, MP480, MP490
PIXMA MP500, MP510, MP520, MP530, MP540, MP550, MP560
PIXMA MP600, MP600R, MP610, MP620, MP630, MP640, MP710
PIXMA MP800, MP800R, MP810, MP830, MP960, MP970, MP980, MP990
PIXMA MX300, MX310, MX330, MX700, MX850, MX860, MX7600
MultiPASS MP700, MP730, PIXMA MP750 (no grayscale)
ImageCLASS MF3110, MF3240, MF4010, MF4018, MF4120, MF4122
ImageCLASS MF4140, MF4150, MF4270, MF4350d, MF4370dn, MF4380dn
ImageCLASS MF4660, MF4690, MF5770, D480
I-SENSYS MF4320d, MF4330d
CanoScan 8800F
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 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 MX320
ImageCLASS MF5630, MF5650, MF5730, MF5750, MF8170c
The backend supports:
* resolutions of 75, 150, 300, 600, 1200, 2400, and 4800 DPI
(some maybe buggy),
* color and grayscale mode,
* a custom gamma table,
* Automatic Document Feeder, Simplex and Duplex.
* Transparency Unit, 24 or 48 bits depth.
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 devices is in the form pixma:aaaa_bbbbb where
aaaa is the scanners model and bbbb is the hostname or ip-adress.
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).
/etc/sane.d/pixma.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below). The files contains an optional list of
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:
bjnp://<host>
where host is the hostname or IP address of the scanner, e.g.
bjnp://10.0.1.4 or bjnp://myscanner.mydomain.org. 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. 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 8612 on the scanner. So
you will have to allow outgoing traffic TO port 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 interfaces). The broadcast is sent
FROM port 8612 TO port 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.
You will therefore have to allow incoming packets TO port 8612 on your
computer.
So in short: open the firewall for all traffic from your computer to
port 8612 AND to port 8612 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.
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/BJNP traffics
21 full dump USB/BJNP traffic
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).

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.
