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:

The following models may use partly the same Pixma protocol as other devices listed above,
but may still need some work. They are declared in the backend as experimental and need
the environment variable PIXMA_EXPERIMENT=1 to get recognized and activated. Snoop logs
are required to further investigate, please contact the sane-devel mailing list.

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.) sane-pixma backend also
provides the following options, 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.
adf-wait
This option enables and sets the time in seconds waiting for a document inserted
into the Automatic Document Feeder. The maximum allowed waiting time is 3600 sec
(= 1 hour).
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 backend 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 = photo, 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.
document-type
(read only) Returns the type of the scanned document if the scanner provides that
data. Known values: 1 = Document, 2 = Photo, 3 = Auto scan. Not all scanners can
provide this data.
adf-status
(read only) Returns the status of the document feeder if the scanner provides that
data. Known values: 1 = ADF empty, 2 = ADF filled. Not all scanners can provide
this data.
adf-orientation
(read only) Returns the scan orientation of the medium scanned from ADF if the
scanner provides that data. Known values: 1 = Portrait, 2 = Landscape. Not all
scanners can provide this data.
FILES
/usr/lib/x86_64-linux-gnu/sane/libsane-pixma.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/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 file contains an optional list of networked scanners using the BJNP or MFNP
protools (See below for datails on networking support for scanners). Normally only
scanners that cannot be auto-detected because they are on a different subnet shall
be listed here. If you do not use Linux and your OS does not allow enumeration of
interfaces (i.e. it does not support the getifaddrs() qfunction) you also may need
to add your scanner here as well.
Scanners shall be listed in the configuration file as follows:
<method>://<host>[:port][/timeout=<value>]
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.
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 timeouts can be set using the bjnp-timeout parameter as
follows:
bjnp-timeout=<value>
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 setting 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.
If so desired networking can be disabled as follows:
- If the first non-commented line contains networking=no all networking will
be disabled. This will cause all further statements in the configuration
file to be ignored.
- A line that contains auto_detection=no will cause auto-detection to be
skipped. Explicitly defined network scanners will still be probed.
USB SUPPORT
USB scanners will be auto-detected and require no configuration.
NETWORKING SUPPORT
The sane-pixma backend supports network scanners using the so called Canon BJNP and MFNP
protocols.
Canon seems to be dropping support for these protocols in recent scanners. To verify if
your scanner supports one of these protocols, check the content of the _scanner._tcp
service entry in mDNS/DNS-SD (using for example avahi-discover(1)). If that does not list
port 8610 or 8612 your scanner probably does not support the mfmp or bjnp protols.
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 sane-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 sane-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 sane-pixma backend sends a broadcast
on all direct connected subnets it can find (provided your OS allows for enumeration of
all network 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. On *NIX systems, 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).
