NAME
sane-plustekpp - SANE backend for Plustek parallel port
flatbed scanners
DESCRIPTION
The sane-plustekpp 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. The access of the scanner is either done directly
by the backend or via kernel module, called ptdrv which can
be created out of the plustekpp backend code - see also
section BUILDING THE KERNEL MODULE for further information.
SUPORTED DEVICES
At present, the following scanners should work with this
backend and/or the kernel module:

DEVICE NAMES
This backend works in two modes, the so called "direct-mode"
and the "kernel-mode". In direct-mode, the user-space back-
end is used, in kernel-mode, you should have a kernel-module
named ptdrv loaded. This backends default device is:
0x378
This "default device" will be used, if no configuration file
can be found. It is rather 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
/etc/sane.d/plustekpp.conf
See this file for examples.

SANE Scanner Access Now Easy sane-plustekpp(5)
CONFIGURATION
This section describes the backends' configuration file
entries. The file is located at:
/etc/sane.d/plustekpp.conf
For a proper setup, you will need at least two entries:
[direct]
device 0x378
or
[kernel]
device /dev/ptdrv
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. kernel should only be used, when a
kernel-module has been built out of the backend sources. See
below for more instructions about this.
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
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/negative

m = 4
OpticPro 9636P override (works if OP9636 has been
detected) disables backends transparency/negative
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)
See the plustekpp.conf file for examples.
BUILDING THE KERNEL MODULE
As mentioned before, the plustekpp backend code can also be
compiled and installed as linux kernel module. To do so, you
will need the source-files of this sane-backend installa-
tion. Unpack this tar-ball and go to the directory:
sane-backends/doc/plustek
Within this directory, you should find a script called:
MakeModule.sh
Now if your Linux kernelsources are installed correctly, it
should be possible to build, install and load the module
ptdrv. Please note, that the kernelsources need to be con-
figured correctly. Refer to your distributions manual on
how this is done. As root user, try
./MakeModule.sh
the script will try and get all necessary information about
your running kernel and will lead you through the whole ins-
tallation process.
Note: Installing and loading the can superuser.
KERNEL MODULE SETUP
The configuration of the kernel module is done by providing
some or more options found below to the kernel module at
load time. This can be done by invoking insmod with the
appropriate parameters or appending the options to the file
/etc/modules.conf (kernel < 2.6.x) or /etc/modprobe.conf
(kernel >= 2.6.x)
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
sane-backends 1.0.19Last change: 18 June 2004 4
SANE Scanner Access Now Easy sane-plustekpp(5)
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 nor-
maly 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 SP mode and 2 --> use EP
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/negative
capabilities
m = 4
OpticPro 9636P override (works if OP9636 has been
detected) disables backends transparency/negative
capabilities
sane-backends 1.0.19Last change: 18 June 2004 5
SANE Scanner Access Now Easy sane-plustekpp(5)
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 ptdrv
pre-install ptdrv modprobe -k parport
options ptdrv lampoff=180 warmup=15 port=0x378 lOffonEnd=0
For multidevice support, simply add values separated by com-
mas to the different options
options ptdrv port=0x378,0x278 mov=0,4 slowIO=0,1 for-
ceMode=0,1
Remember to call depmod after changing /etc/conf.modules.
PARALEL PORT MODES
The current driver works best, when the parallel port has
been set to EP-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 SP mode, as this mode
should work with all Linux supported parallel 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 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.
See the plustekpp.conf file for examples.

ENVIRONMENT
SANECONFIGDIR
This environment variable specifies the list of direc-
tories that may contain the configuration file. Under
UNIX, the directories are separated by a colon (`:'),
under OS/2, they are separated 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 /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 SANECONFIGDIR to
"/tmp/config:" would result in directories
"tmp/config", ".", and "/etc/sane.d" being searched (in
this order).
SANEDEBUGPLUSTEKP
If the library was compiled with debug support enabled,
this environment variable controls the debug level for
this backend. Higher debug levels increase the verbos-
ity of the output.
Example: export SANEDEBUGPLUSTEKP=10

your favorite scan-frontend (i.e. xscanimage).
i.e.: export SANEDEBUGPLUSTEKP=20 ; xscanimage
The value controls the verbosity of the backend.
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 CD-
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
