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:

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

/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

/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 disable 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 connected 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 --> autodetection, 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

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 parallel 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 resolution modes. If you encounter sporadic corrupted images (parts duplicated or shifted horizontally) kill all other applications before scanning 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
/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 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, simply load the USB subsystem and plug in your scanner. Then do a cat /proc/bus/usb/devices and look for the scanner.

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.
