sane-pixma(5) SANE Scanner Access Now Easy sane-pixma(5)
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) back-
end that provides access to Canon PIXMA / i-SENSYS / imageCLASS / im-
ageRUNNER multi-function devices (All-in-one printers) and the Canon
CanoScan Flatbed/TPU scanners. The backend implements both the USB in-
terface 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 are not well tested and/or the scanner sometimes
hangs and must be switched off and on.
PIXMA MP760, MP770, MP780, MP790
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 de-
clared in the backend so that they get recognized and activated. Feed-

The following models may use partly the same Pixma protocol as other de-
vices listed above, but may still need some work. They are declared in
the backend as experimental and need the environment variable PIXMA_EX-
PERIMENT=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 respec-
tively.
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 pe-
ripheral.
This backend, based on cloning original Canon drivers protocols, is in a
production stage. Design 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 maxi-
mum 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 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 (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 automati-
cally from the scanner. This option is left for backward compati-
bility 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 re-
turned 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 scan-
ners 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 scan-
ner 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 scan-
ner 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_CON-
FIG_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 getifad-
drs() function) 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>]
method indicates the protocol used. bjnp is used for inkjet
multi-functionals and mfnp is used for laser multi-func-
tionals).
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 lit-
eral IPv6-address or bjnp://myscanner.mydomain.org for a
hostname.
port is optional and is normally implied by the method. Port
8610 is the standard port for mfnp, 8612 for bjnp.
timeout
scanner-specific timeout value for the network protocol.
The value is in ms.
Define each scanner each on a separate line.
More globally-applicable timeouts can be set using the bjnp-time-
out 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 set-
ting is used for 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:
networking=no
If the first non-commented line contains this entry all
networking will be disabled. All further statements in
the configuration file will be ignored.
auto_detection=no
This line will cause auto-detection to be skipped. Ex-
plicitly 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 scan-
ners. 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 com-
puter 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 de-
scribed 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 al-
low 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 en-
vironment variable controls the debug level for this backend it-
self. Higher value increases the verbosity and includes the in-
formation 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 en-
vironment 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 lev-
els.
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 experimental support for
further 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 direc-
tories are separated by a colon (`:'), under OS/2, they are sepa-
rated 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).
