.SH NAME
sane\-plustek \- SANE backend for LM983[1/2/3] based
USB flatbed scanners
.SH DESCRIPTION
The
.B sane\-plustek
library implements a SANE (Scanner Access Now Easy) backend that
provides access to USB flatbed scanners based on National Semiconductor
Merlin chipsets (LM9831, 9832 and 9833).
If you're looking for parallel-port support for Plustek scanner
please refer to the
.BR sane\-plustek_pp (5)
backend.

.SH "SUPPORTED DEVICES"
The Backend is able to support USB scanner based on the National
Semiconductor chipsets LM9831, LM9832 and LM9833. The following tables
show various devices which are currently reported to work. If your
Plustek scanner has another Product ID, then the device is
.B NOT
supported by this backend.

The SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner
and is supported by the
.BR sane\-artec (5)
backend.
.br
Only the National Semiconductor LM983[1/2/] based devices of Plustek

.SH "CONFIGURATION"
To use your scanner with this backend, you need at least two
entries in the configuration file
.I @CONFIGDIR@/plustek.conf
.RS
.PP
.I [usb] vendor-id product-id
.br
.I device /dev/usbscanner
.RE
.PP
.I [usb]
tells the backend, that the following devicename (here
.IR /dev/usbscanner )
has to be interpreted as USB scanner device. If vendor- and
product-id has not been specified, the backend tries to
detect this by its own. If device is set to
.I auto
then the next matching device is used.
.br
The following options can be used for a default setup of
your device. Most of them are also available through
the frontend.
.PP
.B
The Options:
.PP
option warmup t
.RS
.I t
specifies the warmup period in seconds, if set to \-1, the
automatic warmup function will be used
.RE
.PP
option lampOff t
.RS
.I t
is the time in seconds for switching off the lamps in
standby mode
.RE
.PP
option lOffonEnd b
.RS
.I b
specifies the behaviour when closing the backend, 1 --> switch
lamps off, 0 --> do not change lamp status
.RE
.PP
option mov m
.RS
.I m
is the model override switch. It works only with Mustek
BearPaw devices.

You have to make sure, that the USB subsystem is loaded
correctly and you have access to the device-node. For
more details see
.BR sane\-usb (5)
manpage. You might use
.BR sane\-find\-scanner (1)
to check that you have access to your device.
.PP
.B Note:
.br
If there's no configuration file, the backend defaults to
.B device auto

.SH FILES
.TP
.I @CONFIGDIR@/plustek.conf
The backend configuration file
.TP
.I @LIBDIR@/libsane\-plustek.a
The static library implementing this backend.
.TP
.I @LIBDIR@/libsane\-plustek.so
The shared library implementing this backend (present on systems that
support dynamic loading).

.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
.IR @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
.IR "tmp/config" ,
.IR "." ,
and
.I "@CONFIGDIR@"
being searched (in this order).
.TP
.B SANE_DEBUG_PLUSTEK
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:
export SANE_DEBUG_PLUSTEK=10

.SH "CONTACT AND BUG-REPORTS"
Please send any information and bug-reports to:
.br
.B SANE Mailing List
.PP
Additional info and hints can be obtained from our
.br
Mailing-List archive at:
.br
.I http://www.sane\-project.org/mailing\-lists.html
.PP
To obtain debug messages from the backend, please set the
environment-variable
.B SANE_DEBUG_PLUSTEK
before calling your favorite scan-frontend (i.e.
.BR scanimage (1)), i.e.:

.br
.I export SANE_DEBUG_PLUSTEK=20 ; scanimage
.PP
The value controls the verbosity of the backend. Please note, that
values greater than 24 force the backend to output raw data files,
which could be rather large. The ending of these files is ".raw".
For problem reports it should be enough the set the verbosity to
13.

.SH "KNOWN BUGS & RESTRICTIONS"

.PP
* The driver does not support these manic scalings up
to 16 times the physical resolution. The only scaling
is done on resolutions between the physical resolution
of the CCD-/CIS-sensor and the stepper motor i.e. you
have a 600x1200 dpi scanner and you are scanning using
800dpi, so scaling is necessary, because the sensor only
delivers 600dpi but the motor is capable to perform
1200dpi steps.
.PP
* Plusteks' model policy is somewhat inconsistent. They
sell technically different devices under the
same product name. Therefore it is possible that some
devices like the UT12 or U12 won't work \- please check
the model list above and compare the product-id to
the one your device has.
.PP
* Negative/Slide scanning quality is poor.
