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

NAME

sane-plustek - SANE backend for LM983[1/2/3] based USB flatbed scanners

DESCRIPTION

The 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 sane-plustek_pp(5) backend.

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 NOT supported by this backend.

OTHER PLUSTEK SCANNERS

For parallelport device support see the sane-plustek_pp(5) backend.
The SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner and is supported by the sane-artec(5) backend.
Only the National Semiconductor LM983[1/2/] based devices of Plustek are supported by this backend. Older versions of the U12, the UT12, the U1212 and U1248 (GrandTech chipset) are not supported.

CONFIGURATION

To use your scanner with this backend, you need at least two entries in the configuration file /etc/sane.d/plustek.conf

[usb] vendor-id product-id
device /dev/usbscanner

[usb] tells the backend, that the following devicename (here /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 auto then the next matching device is used.
The following options can be used for a default setup of your device. Most of them are also available through the frontend.

The Options:

option warmup t

t specifies the warmup period in seconds, if set to -1, the automatic warmup function will be used

option lampOff t

t is the time in seconds for switching off the lamps in standby mode

option lOffonEnd b

b specifies the behaviour when closing the backend, 1 --> switch lamps off, 0 --> do not change lamp status

option mov m

m is the model override switch. It works only with Mustek BearPaw devices. 
m/PID |    0x1000    |    0x1001
------+--------------+--------------


  0   | BearPaw 1200 | BearPaw 2400


  1   |  no function | BearPaw 1200

option invertNegatives b

b 0 --> do not invert the picture during negative scans,
1 --> invert picture

option cacheCalData b

b 0 --> do not save calibration results,
1 --> save results of calibration in ~/.sane/ directory

option altCalibration b

b 0 --> use standard calibration routines,
1 --> use alternate calibration (only non Plustek devices, standard for CIS devices)

option skipFine b

b 0 --> perform fine calibration,
1 --> skip fine calibration (only non Plustek devices)

option skipFineWhite b

b 0 --> perform white fine calibration,
1 --> skip white fine calibration (only non Plustek devices)

option skipDarkStrip b

b 0 --> perform dark calibration, with enabled lamp using the dark calibration strip of the scanner. If the scanner does not have such a strip, the alternative way is to switch off the lamp during this step.
1 --> always switch off the lamp for dark calibration, even a black strip is available

option skipCalibration b

b 0 --> perform calibration,
1 --> skip calibration (only non Plustek devices)

option enableTPA b

b 0 --> default behaviour, specified by the internal tables,
1 --> override internal tables and allow TPA mode (EPSON/UMAX only)

option posOffX x
option posOffY y
option tpaOffX x
option tpaOffY y
option negOffX x
option negOffY y

x y By using this settings, the user can adjust the given image positions. Please note, that there's no internal range checking for this feature.

option posShadingY p
option tpaShadingY p
option negShadingY p

p overrides the internal shading position. The values are in steps. Please note, that there's no internal range checking for this feature.

option redGamma r
option greenGamma g
option blueGamma b
option grayGamma gr

r g b gr
By using these values, the internal linear gamma table (r,g,b,gr = 1.0) can be adjusted.

option red_gain r
option red_offset ro
option green_gain g
option green_offset go
option blue_gain b
option blue_offset bo

r g b ro go bo These values can be used to set the gain and offset values of the AFE for each channel. The range is between 0 and 63. -1 means autocalibration.

See the plustek.conf file for examples.

Note:
You have to make sure, that the USB subsystem is loaded correctly and you have access to the device-node. For more details see sane-usb(5) manpage. You might use sane-find-scanner(1) to check that you have access to your device.

Note:
If there's no configuration file, the backend defaults to device auto

FILES

/etc/sane.d/plustek.conf
The backend configuration file
/usr/lib/x86_64-linux-gnu/sane/libsane-plustek.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-plustek.so
The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

This environment variable specifies the list of directories that may contain the configuration file. On *NIX systems, 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 /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).
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

CONTACT AND BUG-REPORTS

Please send any information and bug-reports to:
SANE Mailing List

Additional info and hints can be obtained from our mailing-List archive at: http://www.sane-project.org/mailing-lists.html.

To obtain debug messages from the backend, please set the environment-variable SANE_DEBUG_PLUSTEK before calling your favorite SANE frontend (e.g. scanimage(1)):

export SANE_DEBUG_PLUSTEK=20 ; scanimage

The value controls the verbosity of the output. Please note that values greater than 24 force the backend to output raw data files which could be rather large. The suffix of these files is ".raw". For problem reports it should be enough the set the verbosity to 13.

KNOWN BUGS & RESTRICTIONS

* 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.

* 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.

* Negative/Slide scanning quality is poor.
