NAME

       sane-plustek  - SANE backend for Plustek parallel port and 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 Plustek parallel port and USB flatbed
       scanners.  The USB support is part of the SANE package  but  for  usage
       with  parallel  port  scanners  you  will  need a kernel module, called
       pt_drv which currently can be downloaded from
       http://www.gjaeger.de/scanner/plustek.html

       !!!Please note that you need the kernel module only for  parallel  port
       scanners!!!


PARALLEL PORT SUPPORT

       At  present,  the  following scanners should work with this backend and
       the corresponding kernel module:

USB SUPPORT

       The Backend is able to support USB scanner based on the National  Semi-
       conductor  chipset 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, as it
       contains unsupported ASICs inside.

OTHER PLUSTEK SCANNERS

       The SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner  and
       is supported by the Artec backend.
       Only  the  National Semiconductor LM9831/2 based devices of Plustek are
       supported by this driver. Older versions of  the  U12,  the  UT12,  the
       U1212 and U1248 (GrandTech chipset) are not supported.

DEVICE NAMES

       This backend expects a default device called:

              /dev/pt_drv

       This  default  device  will  be  used,  if no configuration file can be
       found.

       The device-driver is currently not part of the SANE  distribution.   It
       has to be downloaded from:
       http://www.gjaeger.de/scanner/plustek.html
       See  the INSTALL file there for a proper setup. Currently only Linux is
       supported by this driver (Kernel 2.2.x and higher).

       As the backend and the driver support up to four devices per system, it
       is possible to specify them in the configuration file

              /usr/local/etc/sane.d/plustek.conf

       See the plustek.conf file for examples.


CONFIGURATION

       The configuration of this backend can be divided into two sections:

       CONFIGURATION - parallel port scanner

       CONFIGURATION - USB scanner

       Please make sure, that the configuration matches the real world, namely
       your configuration. And note again, .I pt_drv is only needed


CONFIGURATION - PARALLEL PORT SCANNER

       Beside the kernel-module options, which are described below,  you  need
       to enable the parallel port device in the configuration file

              /usr/local/etc/sane.d/plustek.conf

       For a proper setup, you will need at least two entries:

       [parport]

       device /dev/pt_drv

       parport   tells  the  backend,  that  the  following  devicename  (here
       /dev/pt_drv ) has to be interpreted as parallel port scanner device.

       To have this device, you will need to setup the kernel module.  As  the
       driver is a loadable kernel module, it is configured by invoking insmod
       with the appropriate parameters or appending the options  to  the  file
       /etc/conf.modules

       The Options:
       lampoff=lll
              The  value  lll  tells  the  driver,  after  how many seconds to
              switch-off the lamp(s). The default value is 180.  0  will  dis-
              able this feature.
              HINT:  Do  not  use  a  value  that  is too small, because often
              switching on/off the lamps will reduce their lifetime.

       port=ppp
              ppp specifies the port base address, where the scanner  is  con-
              nected to. The default value is 0x378 which normaly is standard.

       warmup=www
              www specifies the time in seconds, how long a lamp has to be on,
              until the driver will start to scan. The default value is 30.

       lOffonEnd=e
              e  specifies  the  behaviour  when  unloading  the driver, 1 -->
              switch lamps off, 0 --> do not change lamp status

       slowIO=s
              s specifies which I/O functions the driver should use, 1 --> use
              delayed functions, 0 --> use the non-delayed ones

       forceMode=fm
              fm  specifies  port  mode which should be used, 0 --> autodetec-
              tion, 1 --> use SPP mode and 2 --> use EPP mode

       mov=m
              m =0 - default: no override
              m =1 - OpticPro 9630PL override (works if OP9630
                     has been detected) forces legal size (14")
              m =2 - Primax 4800Direct override (works if OP600
                     has been detected) swaps red/green color
              m =3 - OpticPro 9636 override (works if OP9636 has
                     been detected) disables backends
                     transparency/negativ capabilities
              m =4 - OpticPro 9636P override (works if OP9636 has
                     been detected) disables backends
                     transparency/negativ capabilities
              m =5 - OpticPro A3I override (works if OP12000 has
                     been detected) enables A3 scanning
              m =6 - OpticPro 4800P override (works if OP600
                     has been detected) swaps red/green color
              m =7 - Primax 4800Direct 30bit override (works if OP4830
                     has been detected)

       Sample entry for file /etc/modules.conf :
       alias char-major-40 pt_drv
       pre-install pt_drv modprobe -k parport
       options  pt_drv  lampoff=180  warmup=15  port=0x378  lOffonEnd=0  mov=0
       slowIO=0 forceMode=0

       For  multidevice  support, simply add values separated by commas to the
       different options
       options pt_drv port=0x378,0x278 mov=0,4 slowIO=0,1 forceMode=0,1

       Remember to call depmod after changing /etc/conf.modules.

       PARALLEL PORT MODES

       The current driver works best, when the parallel port has been  set  to
       EPP-mode.  When detecting any other mode such as ECP or PS/2 the driver
       tries to set to a faster, supported mode. If this fails,  it  will  use
       the  SPP mode, as this mode should work with all Linux supported paral-
       lel ports.

       Former Plustek scanner models (4830, 9630) supplied a ISA parallel port
       adapter card. This card is not supported by the driver.

       The  ASIC 96001/3 based models have sometimes trouble with high resolu-
       tion modes. If you encounter sporadic corrupted  images  (parts  dupli-
       cated or shifted horizontally) kill all other applications before scan-
       ning and (if sufficient memory available) disable swapping.


CONFIGURATION - USB SCANNER

       To use the USB device with this backend, you need at least two  entries
       in the configuration file
       /usr/local/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  ven-
       dor- and product-id has not been specified, the backend tries to detect
       this by its own. If device ist set to auto
        then the next matching device is used.

       The Options:

       option warmup t
              t specifies the warmup period in seconds

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

       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 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 green_gain g
       option blue_gain b
              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.


       See the plustek.conf file for examples.

       Note:
       You have to make sure, that the USB subsystem is loaded  correctly  and
       the  module  scanner has been loaded too. To make this module recognize
       your scanner, you  might  have  to  add  the  following  line  to  your
       /etc/modules.conf :
       options scanner vendor=0x7b3 product=0x17

       If you're not sure about the vendor and product id of your device, sim-
       ply load the USB subsystem and plug in your  scanner.  Then  do  a  cat
       /proc/bus/usb/devices and look for the scanner.

       To obtain debug messages from the backend, please set the  environment-
       variable  SANE_DEBUG_PLUSTEK before calling your favorite scan-frontend
       (i.e. xscanimage).
       i.e.: export SANE_DEBUG_PLUSTEK=20 ; xscanimage

       The value controls the verbosity of the backend. Please note, that val-
       ues  greater  than 19 force the backend to output raw data files, which
       could be rather large. The ending of these files is ".raw".  For  prob-
       lem reports it should be enough the set the verbosity to 13.


KNOWN BUGS & RESTRICTIONS

       * The Halftoning works, but the quality is poor
       * Printers (especially HP models) will start to
         print during scanning. This in fact is a problem
         to other printers too, using bidirectional protocol
         (see www.plustek.com (TAIWAN) page for further details)
       * 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 CDD-sensor and the stepper motor i.e. you have a
         600x1200 dpi scanner and you are scanning using 800dpi,
         so scaling is necesary, because the sensor only delivers
         600dpi but the motor is capable to perform 800dpi steps.
       * On some devices, the pictures seems to be bluished

       ASIC 98001 based models:
       * The 300dpi transparency and negative mode does not work
         correctly.
       * There is currently no way to distinguish a model with
         and without transpareny unit.
       * The scanned images seem to be too dark (P9636T)

       ASIC 96003/1 based models:
       * 30bit mode is currently not supported.
       * On low-end systems and under heavy system load, the
         driver will loosing data, this might causes the sensor
         to hit the scan-bed and/or the picture is corrupted.
       * The scanspeed on 600x1200 dpi models is slow.
       * The scanquality of the A3I is poor

       USB models:
       * Plusteks' model policy is somewhat inconsistent. This
         means, they sell technical 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 scanning quality is poor.
