sane-pixma(5) SANE Scanner Access Now Easy sane-pixma(5)NAMEsane-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 USB inter‐
face and network interface using Canon's BJNP protocol. The network
interface supports scanners over IPv4 as well as IPv6.
Currently, the following models work with this backend:
PIXMA MG2100, MG3100, MG4200, MG5100, MG5200, MG5300
PIXMA MG6100, MG6200, MG6300, MG8200
PIXMA MP140, MP150, MP160, MP170, MP180, MP190
PIXMA MP210, MP220, MP230, MP240, MP250, MP260, MP270, MP280

hangs and must be switched off and on.
PIXMA MP760, MP770, MP780, MP790
PIXMA MX360
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.

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 mod‐
els,
* 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 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 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‐
formances.
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.
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.
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
(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
reasons.
button-1 button-2
(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.
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 = 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.
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.
FILES
/usr/lib64/sane/libsane-pixma.a
The static library implementing this backend.
/usr/lib64/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 for IPv4,
bjnp://[2001:888:118e:18e2:21e:8fff:fe36:b64a] for a literal
IPv6-address or bjnp://myscanner.mydomain.org. Define each scan‐
ner 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. Both IPv4 and IPv6 are supported.
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 sub‐
net 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 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.
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
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
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 net‐
work protocol for this backend. Higher value increases the ver‐
bosity 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 experi‐
mental 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 config‐
uration 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 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 "/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
