sane-plustek_pp(5) SANE Scanner Access Now Easy sane-plustek_pp(5) NAME sane-plustek_pp - SANE backend for Plustek parallel port flatbed scan- ners DESCRIPTION The sane-plustek_pp library implements a SANE (Scanner Access Now Easy) backend that provides access to Plustek ASIC 9600[1/3] and P9800[1/3] based parallel port flatbed scanners. SUPPORTED DEVICES At present, the following scanners should work with this backend: 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 96003 600x1200 dpi 36bit 128Kb OpticPro 12000P/96000P 96003 600x1200 dpi 36bit 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 36bit 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.

The following table will show the relation- ship: Model: Remarks: --------------------------- ---------------------------- BrightScan OpticPro OpticPro P12 DEVICE NAMES This backend's default device is: 0x378 This "default device" will be used if no configuration file can be found. It is the base address of the parallel port on i386 machines. As the backend supports up to four devices, it is possible to specify them in the configuration file /usr/local/etc/sane.d/plustek_pp.conf See this file for examples. CONFIGURATION This section describes the backend's configuration file entries. The file is located at: /usr/local/etc/sane.d/plustek_pp.conf For a proper setup, you will need at least two entries: [direct] device 0x378 direct tells the backend, that the following devicename (here 0x378) has to be interpreted as parallel port scanner device. In fact it is the address to use. Alternatively you can use /dev/parport0 if the backend has been compiled with libieee1284 support. Further 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 mov m m is the model override switch, which only works in direct mode. m = 0 default: no override m = 1 OpticPro 9630PL override (works if OP9630 has been de- tected) forces legal size (14") m = 2 Primax 4800Direct override (works if OP600 has been de- tected) swaps red/green color m = 3 OpticPro 9636 override (works if OP9636 has been de- tected) disables backends transparency/negative capabili- ties m = 4 OpticPro 9636P override (works if OP9636 has been de- tected) disables backends transparency/negative capabili- ties m = 5 OpticPro A3I override (works if OP12000 has been de- tected) enables A3 scanning m = 6 OpticPro 4800P override (works if OP600 has been de- tected) swaps red/green color m = 7 Primax 4800Direct 30bit override (works if OP4830 has been detected) See the plustek_pp.conf file for examples. 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. If in doubt, enter your BIOS and set it to any mode except ECP. 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. See the plustek_pp.conf file for examples. FILES /usr/local/etc/sane.d/plustek_pp.conf The backend configuration file /usr/local/lib/sane/libsane-plustek_pp.a The static library implementing this backend. /usr/local/lib/sane/libsane-plustek_pp.so The shared library implementing this backend (present on systems that support dynamic loading). ENVIRONMENT SANE_CONFIG_DIR This environment variable specifies the list of directories that may contain the configuration file. On *NIX systems, the direc- tories are separated by a colon (`:'), under OS/2, they are sep- arated 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 /usr/lo- cal/etc/sane.d. If the value of the environment variable ends with the directory separator character, then the default direc- tories are searched after the explicitly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re- sult in directories tmp/config, ., and /usr/local/etc/sane.d be- ing searched (in this order). SANE_DEBUG_PLUSTEK_PP If the library was compiled with debug support enabled, this en- vironment variable controls the debug level for this backend. Higher debug levels increase the verbosity of the output. Example: export SANE_DEBUG_PLUSTEK_PP=10 SEE ALSO sane(7), xscanimage(1), /usr/local/share/doc/sane-backends/plustek/Plustek-PARPORT.changes 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_PP before calling your favorite SANE fron- tend (e.g. xscanimage(1)): export SANE_DEBUG_PLUSTEK_PP=20 ; xscanimage The value controls the verbosity of the output. 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 CCD-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 800dpi steps. * On some devices, the pictures seems bluish 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 transparency 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 under heavy system load the driver may lose data, which can result in picture corruption or cause the sensor to hit the scan bed. * The scanning speed on 600x1200 dpi models is slow. * The scanning quality of the A3I is poor. 14 Jul 2008 sane-plustek_pp(5)
