sane-pixma(5) SANE Scanner Access Now Easy sane-pixma(5)
sane-pixma - SANE backend for Canon Multi-Function Printers and
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 proto-
cols). The network interface supports scanners over IPv4 as well as
IPv6 (MFNP over IPv6 is untested).
Currently, the following models work with this backend:

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

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.

This backend, based on cloning original Canon drivers protocols, is in
a production stage. Designed has been carried out without any applica-
ble manufacturer documentation, probably never available. However, we
have tested it as well as we could, but it may not work in all situa-
tions. You will find an up-to-date status at the project homepage. (See
below). Users feedback is essential to help improve features and per-
Besides "well-known" options (e.g. resolution, mode etc.) pixma backend
also provides the following options, i.e. the options might change in
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
This option enables and sets the time in seconds waiting for a
document inserted into the Automatic Document Feeder. The maxi-
mum allowed waiting time is 3600 sec (= 1 hour).
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
(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
(read only) These options will return the value of the respec-
tive 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.
(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 scan-
ners can provide this data.
target (read only) Returns the value of the target of the scan opera-
tion 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 equiv-
alent to the number of the pressed button. Not all scanners can
provide this data.
(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
The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
The backend configuration file (see also description of
SANE_CONFIG_DIR below). The file contains an optional list of
networked scanners. Normally only scanners that cannot 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 also may need
to add your scanner here as well.
Scanners shall be listed in the configuration file as follows:
where method indicates the protocol used (bjnp is used for
inkjet multi-functionals and mfnp is used for laser multi-func-
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.
A scanner specific timeout value for the network protocol can be
set using the bjnp-timeout parameter. The value is in ms.
Define scanners each on a new line.
More globally applicable tinmeouts can be set using the bjnp-
timeout parameter as follows:
A timeout defined using bjnp-timeout will apply to the following
scanner definitions in the file. If required the bjnp-timeout
setting can be defined multiple times, where each settng will
apply only to the scanners that follow the setting. The last
setting is used for the auto discovered scanners. If not
explicitly set, the default 1000ms setting will apply.
Setting timeouts should only be required in exceptional cases.
USB scanners will be auto-detected and require no configuration.
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
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 traf-
fic 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
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.
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
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
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
Setting to a non-zero value will enable the support for experi-
mental models. You should also set SANE_DEBUG_PIXMA to 11.
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 config-
uration file is searched in two default directories: first, the
current working directory (".") and then in @CONFIGDIR@. If the
value of the environment variable ends with the directory sepa-
rator 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 "@CONFIGDIR@" being searched (in this
