sane-plustek(k) sane-plustek(k) 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 cur- rently can be downloaded from http://home.t-online.de/home/g-jaeger/plustek.html PARALLEL PORT SUPPORT At present, the following scanners should work with this backend and the corresponding kernel module: PLUSTEK SCANNERS Parallelport Model: ASIC: Properties: ---------------------- ----- ------------------------ OpticPro PT12 98003 600x1200 dpi 36bit 512Kb OpticPro P12 98003 600x1200 dpi 36bit 512Kb OpticPro 9636T/12000T 98001 600x1200 dpi 36bit 512Kb OpticPro 12000P Turbo 98001 600x1200 dpi 36bit 512Kb OpticPro 9636P+/Turbo 98001 600x1200 dpi 36bit 512Kb OpticPro 9636P 98001 600x1200 dpi 36bit 512Kb OpticPro 12000P/96000P 96003 600x1200 dpi 30bit 128Kb OpticPro 1236P 96003 600x1200 dpi 30bit 128Kb OpticPro 9600P 96003 600x1200 dpi 30bit 128Kb OpticPro 9630P/FBIV 96003 600x1200 dpi 30bit 128Kb OpticPro 9630PL (14") 96003 600x1200 dpi 30bit 128Kb OpticPro A3I 96003 400x800 dpi 30bit 128Kb OpticPro 600P/6000P 96003 300x600 dpi 30bit 32Kb OpticPro 4831P 96003 300x600 dpi 30bit 32Kb OpticPro 4830P/FBIII 96003 300x600 dpi 30bit 32Kb OpticPro 4800P/FBII 96001 300x600 dpi 24bit 32Kb PRIMAX SCANNERS There are some scanners sold by Primax, but they are in fact Plustek devices.

Only the National Semiconductor LM9831/2 based devices of Plustek are supported by this driver. Older versions of 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 dis- tribution. It has to be downloaded from: http://home.t-online.de/home/g-jaeger/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 configu- ration 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. 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 parame- ters or appending the options to the file /etc/conf.mod- ules The Options: lampoff=lll The value lll tells the driver, after how many sec- onds to switch-off the lamp(p). 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 lOffo- nEnd=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 force- Mode=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, sup- ported 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 mem- ory 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. 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. FILES /etc/sane.d/plustek.conf The backend configuration file /usr/lib/sane/libsane-plustek.a The static library implementing this backend. /usr/lib/sane/libsane-plustek.so The shared library implementing this backend (present on systems that support dynamic loading). /lib/modules/<Kernel-Version>/misc/pt_drv.o The Linux Kernelmodule. CONTACT AND BUG-REPORTS Please send any information and bug-reports to: Plustek Driver Mailing List <plustek@linuxhacker.org> or directly to: Gerhard Jaeger <g.jaeger@earthling.net> Additional info and hints can be obtained from our Mailing-List archive at: http://www.linuxhacker.org/cgi-bin/ezmlm-cgi/3 or directly from the projects' homepage at: http://home.t-online.de/home/g-jaeger/plustek.html 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. 24 January 2002 sane-plustek(k)
