sane-canon630u(5)	 SANE Scanner Access Now Easy	     sane-canon630u(5)

       sane-canon630u - SANE backend for the Canon 630u USB flatbed scanner

       The  sane-canon630u library implements a SANE (Scanner Access Now Easy)
       backend that provides access to the following Canon flatbed scanners:

	      CanoScan 630u
	      CanoScan 636u

       Color scanning is supported at 75, 150, 300, and 600 dpi, and gamma and
       analog gain are adjustable.

       TESTERS	ARE WELCOME. Send your bug reports and comments to Nathan Rut‐
       man <>

       The contents of the 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
       canon630u.conf.	 The  program  sane-find-scanner helps to find out the
       correct device. Under Linux, such a device name could be /dev/usb/scan‐
       ner0 for example.  See sane-usb(5) for details.

       This  product-specific  scanner	driver uses the lower-level kernel USB
       driver	 "scanner".	Check	 for	 "Driver=usbscanner"	 under
       /proc/bus/usb/devices.  If "Driver=(none)", try forcing it with "insmod
       scanner vendor=0x04a9 product=0x2204"

       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.

       This  driver  requires the ability to send USB Control Messages, avail‐
       able in kernel 2.4.12 or later.

       Some users have reported that this driver doesn't work  at  all.	  This
       seems  to  be  a	 hardware  specific  issue, although I don't know what
       exactly the problem is.	If you are having problems, please send me the
       info  in	 /proc/bus/usb/devices, /proc/pci, the kernel scanner.c driver
       version	  from	  /var/log/messages,	and    the     output	  from
       "SANE_DEBUG_CANON630U=12 scanimage > /dev/null"

	      The   backend   configuration  file  (see	 also  description  of
	      SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

	      The  calibration	file used to normalize pixel brightness.  This
	      is calculated every time the scanner is first used after it  has
	      lost power.  Deleting this file will force recalibration.

	      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	 /sys‐
	      tem/resources/sane-backends/1.0.18/etc/sane.d.   If the value of
	      the environment variable ends with the directory separator char‐
	      acter,  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	 "/system/resources/sane-back‐
	      ends/1.0.18/etc/sane.d" being searched (in this order).

	      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.

	      SANE_DEBUG_CANON630U=12 scanimage > /dev/null
