If vendor- and product-id has not been specified, the backend tries to detect this by its own. If device ist set to .I auto then the next matching device is used. .PP .B The Options: .PP option warmup t .RS .I t specifies the warmup period in seconds .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 invertNegatives b .RS .I b 0 --> do not invert the picture during negativ scans, 1 --> invert picture .RE .PP option cacheCalData b .RS .I b 0 --> do not save coarse calibration results, 1 --> save results of coarse calibration in ~/.sane/ directory .RE .PP option altCalibration b .RS .I b 0 --> use standard calibration routines, 1 --> use alternate calibration (only non Plustek .br devices, standard for CIS devices) .RE .PP option skipFine b .RS .I b 0 --> perform fine calibration, 1 --> skip fine calibration (only non Plustek devices) .RE .PP option skipFineWhite b .RS .I b 0 --> perform white fine calibration, 1 --> skip white fine calibration (only non Plustek devices) .RE .PP option skipCalibration b .RS .I b 0 --> perform calibration, 1 --> skip calibration (only non Plustek devices) .RE .PP option enableTPA b .RS .I b 0 --> default behaviour, specified by the internal tables, 1 --> override internal tables and allow TPA mode (EPSON only) .RE .PP option posOffX x .br option posOffY y .br option tpaOffX x .br option tpaOffY y .br option negOffX x .br option negOffY y .RS .I x y By using this settings, the user can adjust the given image positions. .B Please note, that there's no internal range checking for .B this feature. .RE .PP option posShadingY p .br option tpaShadingY p .br option negShadingY p .RS .I p overrides the internal shading position. The values are in steps. .B Please note, that there's no internal range checking for .B this feature. .RE .PP option redGamma r .br option greenGamma g .br option blueGamma b .br option grayGamma gr .RS .I r g b gr .RE By using these values, the internal linear gamma table (r,g,b,gr = 1.0) can be adjusted. .PP option red_gain r .br option green_gain g .br option blue_gain b .RS .I r g b These values can be used to adjust the internally detected gain values of the AFE for each channel. The range is between 0 and 63. .RE .PP See the plustek.conf file for examples. .PP .B Note: .br You have to make sure, that the USB subsystem is loaded correctly and the module .I scanner has been loaded too. To make this module recognize your scanner, you might have to add the following line to your .B "/etc/modules.conf" : .br .I options scanner vendor=0x7b3 product=0x17 .PP .br If you're not sure about the vendor and product id of your device, simply load the USB subsystem and plug in your scanner. Then do a .I cat /proc/bus/usb/devices and look for the scanner. .br Alternatively, the backend is able to access your scanner via libusb. You might use .B sane-find-scanner 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 . So it .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 "CONTACT AND BUG-REPORTS" Please send any information and bug-reports to: .br .B Plustek Driver Mailing List .br or directly to: .br .B Gerhard Jaeger .PP Additional info and hints can be obtained from our .br Mailing-List archive at: .br .B http://www.linuxhacker.org/cgi-bin/ezmlm-cgi/3 .PP or directly from the projects' homepage at: .br .B http://www.gjaeger.de/scanner/plustek.html .PP To obtain debug messages from the backend, please set the environment-variable .I SANE_DEBUG_PLUSTEK before calling your favorite scan-frontend (i.e. xscanimage). .br .B i.e.: export SANE_DEBUG_PLUSTEK=20 ; xscanimage .PP The value controls the verbosity of the backend. Please note, that values greater than 19 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" * The driver does not support these manic scalings up .br to 16 times the physical resolution. The only scaling .br is done on resolutions between the physical resolution .br of the CDD-sensor and the stepper motor i.e. you have a .br 600x1200 dpi scanner and you are scanning using 800dpi, .br so scaling is necesary, because the sensor only delivers .br 600dpi but the motor is capable to perform 800dpi steps. .br * Plusteks' model policy is somewhat inconsistent. This .br means, they sell technical different devices under the .br same product name. Therefore it is possible that some .br devices like the UT12 or U12 won't work - please check .br the model list above and compare the product-id to .br the one your device has. .br * Negative/Slide scanning quality is poor.
