sane-plustek - SANE backend for Plustek parallel port and LM983[1/2/3]
|
|
based USB flatbed scanners

</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-plustek</B> 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
|
|
<B>http://www.gjaeger.de/scanner/plustek.html</B>
|
|

|
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 <B>NOT</B> supported, as it
|
|
contains unsupported ASICs inside.

<H2>OTHER PLUSTEK SCANNERS</H2><PRE>
|
|
The SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner and
|
|
is supported by the <B>Artec</B> 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.

|
<H2>DEVICE NAMES</H2><PRE>
|
|
This backend expects a default device called:
|
|
|
|
<I>/dev/pt</I><B>_</B><I>drv</I>
|
|
|
|
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:
|
|
<B>http://www.gjaeger.de/scanner/plustek.html</B>
|
|
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
|
|
|
|
<I>/usr/local/etc/sane.d/plustek.conf</I>
|
|
|
|
See the plustek.conf file for examples.
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The configuration of this backend can be divided into two sections:
|
|
|
|
<B>CONFIGURATION</B> <B>-</B> <B>parallel</B> <B>port</B> <B>scanner</B>
|
|
|
|
<B>CONFIGURATION</B> <B>-</B> <B>USB</B> <B>scanner</B>
|
|
|
|
Please make sure, that the configuration matches the real world, namely
|
|
your configuration. And note again, .I pt_drv is only needed
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION - PARALLEL PORT SCANNER</H2><PRE>
|
|
Beside the kernel-module options, which are described below, you need
|
|
to enable the parallel port device in the configuration file
|
|
|
|
<I>/usr/local/etc/sane.d/plustek.conf</I>
|
|
|
|
For a proper setup, you will need at least two entries:
|
|
|
|
<I>[parport]</I>
|
|
|
|
<I>device</I> <I>/dev/pt</I><B>_</B><I>drv</I>
|
|
|
|
<I>parport</I> tells the backend, that the following devicename (here
|
|
<I>/dev/pt</I><B>_</B><I>drv</I> ) 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
|
|
<B>/etc/conf.modules</B>
|
|
|
|
<B>The</B> <B>Options:</B>
|
|
lampoff=lll
|
|
The value <I>lll</I> tells the driver, after how many seconds to
|
|
switch-off the lamp(s). The default value is 180. 0 will dis-
|
|
able this feature.
|
|
<B>HINT:</B> Do not use a value that is too small, because often
|
|
switching on/off the lamps will reduce their lifetime.
|
|
|
|
port=ppp
|
|
<I>ppp</I> specifies the port base address, where the scanner is con-
|
|
nected to. The default value is 0x378 which normaly is standard.
|
|
|
|
warmup=www
|
|
<I>www</I> 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
|
|
<I>e</I> specifies the behaviour when unloading the driver, 1 -->
|
|
switch lamps off, 0 --> do not change lamp status
|
|
|
|
slowIO=s
|
|
<I>s</I> specifies which I/O functions the driver should use, 1 --> use
|
|
delayed functions, 0 --> use the non-delayed ones
|
|
|
|
forceMode=fm
|
|
<I>fm</I> specifies port mode which should be used, 0 --> autodetec-
|
|
tion, 1 --> use SPP mode and 2 --> use EPP mode
|
|
|
|
mov=m
|
|
<I>m</I> =0 - default: no override
|
|
<I>m</I> =1 - OpticPro 9630PL override (works if OP9630
|
|
has been detected) forces legal size (14")
|
|
<I>m</I> =2 - Primax 4800Direct override (works if OP600
|
|
has been detected) swaps red/green color
|
|
<I>m</I> =3 - OpticPro 9636 override (works if OP9636 has
|
|
been detected) disables backends
|
|
transparency/negativ capabilities
|
|
<I>m</I> =4 - OpticPro 9636P override (works if OP9636 has
|
|
been detected) disables backends
|
|
transparency/negativ capabilities
|
|
<I>m</I> =5 - OpticPro A3I override (works if OP12000 has
|
|
been detected) enables A3 scanning
|
|
<I>m</I> =6 - OpticPro 4800P override (works if OP600
|
|
has been detected) swaps red/green color
|
|
<I>m</I> =7 - Primax 4800Direct 30bit override (works if OP4830
|
|
has been detected)

|
|
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 <B>not</B> 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.

<B>Note:</B>
|
|
You have to make sure, that the USB subsystem is loaded correctly and
|
|
the module <I>scanner</I> has been loaded too. To make this module recognize
|
|
your scanner, you might have to add the following line to your
|
|
<B>/etc/modules.conf</B> :
|
|
<I>options</I> <I>scanner</I> <I>vendor=0x7b3</I> <I>product=0x17</I>
|
|
|
|
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 <I>cat</I>
|
|
<I>/proc/bus/usb/devices</I> and look for the scanner.

|
To obtain debug messages from the backend, please set the environment-
|
|
variable <I>SANE</I><B>_</B><I>DEBUG</I><B>_</B><I>PLUSTEK</I> before calling your favorite scan-frontend
|
|
(i.e. xscanimage).

<B>i.e.:</B> <B>export</B> <B>SANE_DEBUG_PLUSTEK=20</B> <B>;</B> <B>xscanimage</B>
|
|
|
|
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.

<H2>KNOWN BUGS & RESTRICTIONS</H2><PRE>
|
|
* 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.
