.SH NAME
|
|
sane\-mustek_pp \- SANE backend for Mustek parallel port flatbed scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-mustek_pp
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to Mustek parallel port flatbed scanners and OEM versions.
|
|
|
|
There are 2 classes of Mustek parallel port scanners: regular
|
|
.B CCD
|
|
(cold cathode device) scanners and
|
|
.B CIS
|
|
(contact image sensor) scanners.
|
|
.P
|
|
The current version of this backend supports both CCD type scanners and
|
|
CIS type scanners.
|
|
.P
|
|
The following scanners might work with this backend:

(*) Calibration problems existed with earlier version of
|

this driver. They seem to be solved now.
|
|
.HP
|
|
(**) Problems have been reported in the past for the
|
|
MD/LT9850 type (striped scans, head moving in wrong
|
|
direction at some resolutions). It is not known whether
|
|
the current version of the driver still has these problems.
|
|
.PP
|
|
.B IF YOU HEAR LOUD CLICKING NOISES, IMMEDIATELY UNPLUG THE SCANNER !
|
|
(This holds for any type of scanner).
|
|
.HP
|
|
(***) Possibly, the engine_delay parameter has to be set to 1 ms
|
|
for accurate engine movements.
|
|
.PP
|
|
Please note that this backend is still under construction. Certain models
|
|
are currently not supported and some may never be because the communication
|
|
protocol is still unknown (eg., SE 12000 P).
|
|
.PP
|
|
Some scanners work faster when
|
|
.B EPP/ECP
|
|
is enabled in the BIOS. EPP mode however may lead to hard-locks on some Linux
|
|
systems. If that is the case for you, you can either disable ECP/EPP in your
|
|
BIOS or disable it in the backend itself (see GLOBAL OPTIONS).
|
|
.PP
|
|
Note that the backend needs to run as root or has to have appropriate access
|
|
rights to
|
|
.I /dev/parport*
|
|
if libieee1284 support is compiled in. To allow user
|
|
access to the scanner run the backend through the network interface (see
|
|
.BR saned (8)
|
|
and
|
|
.BR sane\-net (5)).
|
|
Note also that the backend
|
|
.I does not
|
|
support
|
|
.IR "parport sharing" ,
|
|
i.e. if you try printing while scanning, your computer may crash. To enable
|
|
parport sharing, you have to enable
|
|
.BR libieee1284 (3)
|
|
at compile time.
|
|
You may also have to enable the backend explicitly in your
|
|
.IR dll.conf .
|
|
Just remove the hash mark in the line "mustek_pp".
|
|
|
|
.SH "DEVICE DEFINITION"
|
|
This backend allows multiple devices being defined and configured via the
|
|
.I mustek_pp.conf
|
|
file (even simultaneously, provided that they are connected to different
|
|
parallel ports). Please make sure to edit this file
|
|
.B before
|
|
you use the backend.
|
|
.PP
|
|
A device can be defined as follows:
|
|
.PP
|
|
.RS
|
|
.I scanner <name> <port name> <driver>
|
|
.RE
|
|
.PP
|
|
where
|
|
.HP
|
|
.B <name>
|
|
is an arbitrary name for the device, optionally enclosed by double quotes,
|
|
for instance "LifeTec 9350".
|
|
.HP
|
|
.B <port name>
|
|
is the name of the parallel port to which the device is connected. In case
|
|
libieee1284 is used for communication with the port
|
|
.I (default
|
|
.IR setup) ,
|
|
valid port names are
|
|
.BR parport0 ,
|
|
.BR parport1 ,
|
|
and
|
|
.BR parport2 .
|
|
.PP
|
|
In case the backend is configured for raw IO
|
|
.I (old
|
|
.IR setup) ,
|
|
port addresses have to be used instead of port names:
|
|
.BR 0x378 ,
|
|
.BR 0x278 ,
|
|
or
|
|
.BR 0x3BC .
|
|
The mapping of parallel ports (lp0, lp1, and lp2) to these addresses
|
|
can be different for different Linux kernel versions. For instance,
|
|
if you are using a Kernel 2.2.x or better and you have only one
|
|
parallel port, this port is named lp0 regardless of the base address. However,
|
|
this backend requires the base address of your port. If you are not sure which
|
|
port your scanner is connected to, have a look at your
|
|
.IR /etc/conf.modules ,
|
|
.I /etc/modules.conf
|
|
and/or
|
|
.IR /proc/ioports .
|
|
.PP
|
|
If you are unsure which port to use, you can use the magic value
|
|
.BR *
|
|
to probe for your scanner.
|
|
.PP
|
|
.HP
|
|
.B <driver>
|
|
is the driver to use for this device. Currently available drivers are:
|
|
.IP
|
|
.BR cis600 " : for 600 CP, 96 CP & OEM versions"
|
|
.br
|
|
.BR cis1200 " : for 1200 CP & OEM versions"
|
|
.br
|
|
.BR cis1200+ " : for 1200 CP+ & OEM versions"
|
|
.br
|
|
.BR ccd300 " : for 600 IIIE P & OEM version"
|
|
.IP
|
|
.B Choosing the wrong driver can damage your scanner!
|
|
.br
|
|
Especially, using the 1200CP settings on a 600CP can be
|
|
harmful. If the scanner starts making a loud noise, turn
|
|
it off immediately !!!
|
|
.PP
|
|
Using the cis600 driver on a 1200CP or a 1200CP+ is probably not
|
|
dangerous. The cis1200+ driver also works for the 1200CP, and using
|
|
the cis1200 driver on a 1200CP+ will typically result in scans that
|
|
cover only half of the width of the scan area (also not dangerous).
|
|
.PP
|
|
If unsure about the exact model of your OEM version, check the optical
|
|
resolution in the manual or on the box: the 600CP has a maximum optical
|
|
resolution of 300x600 DPI, whereas the 1200CP and 1200CP+ have a maximum
|
|
optical resolution of 600x1200 DPI.
|
|
.PP

Examples:
|
|
.PP
|
|
.RS
|
|
scanner "LifeTec 9350" 0x378 cis1200
|

.RE
|
|
|
|
If in doubt which port you have to use, or whether your scanner is
|
|
detected at all, you can use
|
|
.I sane\-find\-scanner \-p
|
|
to probe all configured ports.
|
|
|
|
.SH CONFIGURATION
|
|
.PP
|
|
The contents of the
|
|
.I mustek_pp.conf
|
|
file is a list of device definitions and device options that correspond to
|
|
Mustek scanners. Empty lines and lines starting with a hash mark (#) are
|
|
ignored. Options have the following format:
|
|
.PP
|
|
.RS
|
|
.I option <name> [<value>]
|
|
.RE
|
|
.PP
|
|
Depending on the nature of the option, a value may or may not be present.
|
|
Options always apply to the scanner definition that precedes them. There
|
|
are no global options. Options are also driver-specific: not all drivers
|
|
support all possible options.
|
|
|
|
.SS Common options
|
|
.TP
|
|
.B bw <value>
|
|
Black/white discrimination value to be used during lineart scanning. Pixel
|
|
values below this value are assumed to be black, values above are
|
|
assumed to be white.
|
|

|
.SS CIS driver options
|
|
.TP
|
|
.B top_adjust <value>
|
|
Vertical adjustment of the origin, expressed in millimeter (floating point).
|
|
This option can be used to calibrate the position of the origin, within
|
|
certain limits. Note that CIS scanners are probably temperature sensitive, and
|
|
that a certain inaccuracy may be hard to avoid. Differences in offset between
|
|
runs in the order of 1 to 2 mm are not unusual.
|
|
.br
|
|
Default value: 0.0
|
|
.br
|
|
Minimum: \-5.0
|
|
.br
|

Maximum: 5.0
|
|
.br
|
|
.sp
|
|
Example: option top_adjust \-2.5
|
|
.TP
|
|
.B slow_skip
|
|
Turns fast skipping to the start of the scan region off. When the region to
|
|
scan does not start at the origin, the driver will try to move the scanhead
|
|
to the start of the scan area at the fastest possible speed. On some models,
|
|
this may not work, resulting in large inaccuracies (up to centimeters).
|
|
By setting this option, the driver is forced to use normal speed during
|
|
skipping, which can circumvent the accuracy problems. Currently, there are
|
|
no models for which these inaccuracy problems are known to occur.
|
|
.sp
|
|
By default, fast skipping is used.
|
|
.sp
|
|
Example: option slow_skip
|
|
.TP
|
|
.B engine_delay <value>
|
|
Under normal circumstances, it is sufficient for the driver to wait for the
|
|
scanner signaling that the engine is stable, before a new engine command can
|
|
be transmitted. In rare cases, certain scanners and/or parallel port chipsets
|
|
appear to prevent reliable detection of the engine state. As a result, engine
|
|
commands are transmitted too soon and the movement of the scanner head becomes
|
|
unreliable. Inaccuracies ranging up to 10 cm over the whole vertical scan
|
|
range have been reported. To work around this problem, the engine_delay option
|
|
can be set. If it is set, the driver waits an additional amount of time after
|
|
every engine command, equal to the engine_delay parameter, expressed in
|
|
milliseconds. It practice an engine_delay of 1 ms is usually sufficient. The
|
|
maximum delay is 100 ms.
|
|
.sp
|
|
Note that every additional ms of delay can add up to 14 seconds to the total
|
|
scanning time (highest resolution), so an as small as possible value is
|
|
preferred.
|

.B top <value>
|
|
Number of scanlines to skip to the start of the scan area. The number can
|
|
be any positive integer. Values known to me are 47 and 56.
|

|
.B sane-\mustek_pp
|
|
backend by global
|
|
options which precede any scanner definition in the
|
|
.I mustek_pp.conf
|

.TP
|
|
.B no_epp
|
|
Disable parallel port mode EPP: works around a known bug in the Linux parport
|
|
code. Enable this option, if the backend hangs when trying to access the
|
|
parallel port in EPP mode.
|
|
.sp
|

.SH FILES
|
|
.TP
|

|
.B SANE_CONFIG_DIR
|

below).

|
.TP
|
|
.I @LIBDIR@/libsane\-mustek_pp.a

|
|
.TP
|
|
.I @LIBDIR@/libsane\-mustek_pp.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B SANE_CONFIG_DIR
|
|
This environment variable specifies the list of directories that may
|
|
contain the configuration file. On *NIX systems, 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
|
|
.IR @CONFIGDIR@ .
|
|
If the value of the
|
|
environment variable ends with the directory separator character, then
|
|
the default directories are searched after the explicitly specified
|
|
directories. For example, setting
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories
|
|
.IR "tmp/config" ,
|
|
.IR "." ,

|
and
|
|
.I "@CONFIGDIR@"
|
|
being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_MUSTEK_PP
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend. E.g.,

|
a value of 128 requests all debug output to be printed. Smaller
|
|
levels reduce verbosity.
