.SH NAME
|
|
sane-canon630u \- SANE backend for the Canon 630u USB flatbed scanner
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane-canon
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to the following Canon flatbed scanners:
|
|
.PP
|
|
.RS
|
|
CanoScan 630u
|
|
.br
|
|
CanoScan 636u (hopefully)
|
|
.br

|
|
IMPORTANT: this is alpha code. Although there are no known bugs at this
|
|
time, this code uses the Linux USB kernel drivers, which are currently
|
|
in active development. So it may not work, your computer might even hang, and it cannot
|
|
be excluded (although I consider it extremely unprobable) that your scanner
|
|
will be damaged.
|
|

|
|
That said, TESTERS ARE WELCOME. Send your bug reports and comments to

|
.SH "DEVICE NAMES"
|
|
This backend expects device names of the form:
|
|
.PP
|
|
.RS
|
|
.I special
|
|
.RE
|
|
.PP
|
|
Where
|
|
.I special
|
|
is the path-name for the special device that corresponds to a USB scanner
|
|
or a symlink to such a device. The program
|
|
.IR sane-find-scanner
|
|
helps to find out the correct device. Under Linux, such a device name
|
|
could be
|
|
.I /dev/usb/scanner0
|
|
for example. See sane-usb(5) for details.
|
|
|
|
.SH CONFIGURATION
|
|
The contents of the
|
|
.I canon630u.conf
|
|
file is a list of device names that correspond to Canon
|
|
USB scanners. Empty lines and lines starting with a hash mark (#) are
|
|
ignored. Only one device name can be listed in
|
|
.IR canon630u.conf .
|
|
|
|
.SH NOTES
|
|
.PP
|
|
Due to Canon's unwillingness to provide scanner documentation, this
|
|
software was developed by analyzing the USB traffic of the Windows
|
|
2000 driver. So things like the calibration procedure I kind of made up;
|
|
it seems to work for my scanner. If you have complaints, let me know.
|
|
.PP
|
|
This driver requires the ability to send USB Control Messages, available in
|
|
kernel 2.4.12 or later.
|
|
.PP
|
|
This scanner may not be recognized (yet) by the USB kernel driver. Check
|
|
for "Driver=usbscanner" under /proc/bus/usb/devices. If "Driver=(none)",
|
|
try forcing it with "modprobe scanner vendor=0x04a9 product=0x2204"
|
|
.PP
|
|
.SH FILES
|
|
.TP
|
|
.I @CONFIGDIR@/canon630u.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I @LIBDIR@/libsane-canon630u.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane-canon630u.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
.TP
|
|
.I /tmp/canon.cal
|
|
The calibration file used to normalize pixel brightness. This is
|
|
calculated every time the scanner is first used after it has lost power.
|
|
It can be forced to recalibrate by simply deleting this file.
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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 @CONFIGDIR@. 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
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"@CONFIGDIR@" being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_CANON630U
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend. Higher
|
|
debug levels increase the verbosity of the output.
|
|
|
|
Example:
|
|
SANE_DEBUG_CANON630U=12 scanimage > /dev/null
