NAME
sane-mustek_pp - SANE backend for Mustek parallel port flatbed scanners
DESCRIPTION
The 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 CCD (cold cathode
device) scanners and CIS (contact image sensor) scanners.
The current version of this backend supports both CCD type scanners and CIS type
scanners.
The following scanners might work with this backend:

(*) Calibration problems existed with earlier version of this driver. They seem
to be solved now.
(**) 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.
IF YOU HEAR LOUD CLICKING NOISES, IMMEDIATELY UNPLUG THE SCANNER ! (This
holds for any type of scanner).
(***) Possibly, the engine_delay parameter has to be set to 1 ms for accurate
engine movements.
Please note that this backend is still under construction. Certain models are cur-
rently not supported and some may never be because the communication protocol is
still unknown (eg., SE 12000 P).
Some scanners work faster when 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).
Note that the backend needs to run as root or has to have appropriate access rights
to /dev/parport* if libieee1284 support is compiled in. To allow user access to the
scanner run the backend through the network interface (See saned(8) and sane-
net(5)). Note also that the backend does not support parport sharing, i.e. if you
try printing while scanning, your computer may crash. To enable parport sharing,
you have to enable libieee1284 at compile time. This backend also conflicts with
the sane-musteka4s2 backend. You can only enable one of them in your dll.conf. How-
ever, you have to enable the backend explicitly in your dll.conf, just remove the
hash mark in the line "mustek_pp".
DEVICE DEFINITION
This backend allows multiple devices being defined and configured via the
mustek_pp.conf file (even simultaneously, provided that they are connected to dif-
ferent parallel ports). Please make sure to edit this file before you use the back-
end.
A device can be defined as follows:
scanner <name> <port name> <driver>
where
<name> is an arbitrary name for the device, optionally enclosed by double quotes,
for instance "LifeTec 9350".
<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 (default setup),
valid port names are parport0, parport1, and parport2.
In case the backend is configured for raw IO (old setup), port addresses
have to be used instead of port names: 0x378, 0x278, or 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 con-
nected to, have a look at your /etc/conf.modules, /etc/modules.conf and/or
/proc/ioports.
If you are unsure which port to use, you can use the magic value * to probe
for your scanner.
<driver> is the driver to use for this device. Currently available drivers are:
cis600 : for 600 CP, 96 CP & OEM versions
cis1200 : for 1200 CP & OEM versions
cis1200+ : for 1200 CP+ & OEM versions
ccd300 : for 600 IIIE P & OEM version
Choosing the wrong driver can damage your scanner!
Especially, using the 1200CP settings on a 600CP can be harmful. If the
scanner starts making a loud noice, turn it off immediately !!!
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).
If unsure about the exact model of your OEM version, check the optical reso-
lution in the manual or on the box: the 600CP has a maximum optical resolu-
tion of 300x600 DPI, whereas the 1200CP and 1200CP+ have a maximum optical
resolution of 600x1200 DPI.
Examples:
scanner "LifeTec 9350" 0x378 cis1200
scanner Mustek_600CP 0x378 cis600
scanner Mustek_600IIIEP * ccd300
If in doubt which port you have to use, or whether your scanner is detected at all,
you can use sane-find-scanner -p to probe all configured ports.
CONFIGURATION
The contents of the 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:
option <name> [<value>]
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.
Common options
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.
Default value: 127
Minimum: 0
Maximum: 255
Example: option bw 150
CIS driver options
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.
Default value: 0.0
Minimum: -5.0
Maximum: 5.0
Example: option top_adjust -2.5
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 inaccura-
cies (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.
By default, fast skipping is used.
Example: option slow_skip
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 detec-
tion of the engine state. As a result, engine commands are transmitted
too soon and the movement of the scanner head becomes unreliable. Inac-
curacies 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 usu-
ally sufficient. The maximum delay is 100 ms.
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.
Default value: 0
Minimum: 0
Maximum: 100
Example: option engine_delay 1
CCD driver options
top <value> Number of scanlines to skip to the start of the scan area. The num-
ber can be any positive integer. Values known to me are 47 and 56.
Default value: 47
Minimum: 0
Maximum: none
Example: option top 56
waitbank <value> The number of usecs to wait for a bank change. You should not
touch this value actually. May be any positive integer
Default value: 700
Minimum: 0
Maximum: none
Example: option waitbank 700

#
# LifeTec/Medion 9350 on port 0x378
#
scanner "LifeTec 9350" 0x378 cis1200

scanner "Mustek 1200CP plus" 0x278 cis1200+
# Some calibration options (examples!).
option bw 130
option top_skip 0.2
#
# A Mustek 600 III EPP on port parport0
#
scanner "Mustek 600 III EPP" parport0 ccd300
# Some calibration options (examples!).
option bw 130

GLOBAL OPTIONS
You can control the overall behaviour of the mustek_pp backend by global options
which precede any scanner definition in the mustek_pp.conf file.
Currently, there is only one global option:
Global options
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.
Default value: use EPP
Example: option no_epp
FILES
/etc/sane.d/mustek_pp.conf
The backend configuration file (see also description of SANE_CONFIG_DIR
below).
/usr/lib*/sane/libsane-mustek_pp.a
The static library implementing this backend.
/usr/lib*/sane/libsane-mustek_pp.so
The shared library implementing this backend (present on systems that sup-
port dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
This environment variable specifies the list of directories 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 directories are searched
after the explicitly specified directories. For example, setting SANE_CON-
FIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".", and
"/etc/sane.d" being searched (in this order).
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.
level debug output
------- ------------------------------
0 nothing
1 errors
2 warnings & minor errors
3 additional information
4 debug information
5 code flow (not supported yet)
6 special debug information
SANE_DEBUG_SANEI_PA4S2
This variable sets the debug level for the SANE interface for the Mustek
chipset A4S2. Note that enabling this will spam your terminal with some mil-
lion lines of debug output.

BUGS
Too many... please send bug reports to sane-devel AT lists.org (note
that you have to subscribe first to the list before you can send emails... see
http://www.sane-project.org/mailing-lists.html)
BUG REPORTS
If something doesn't work, please contact us (Jochen for the CCD scanners, Eddy for
the CIS scanners). But we need some information about your scanner to be able to
help you...
SANE version
run "scanimage -V" to determine this
the backend version and your scanner hardware
run "SANE_DEBUG_MUSTEK_PP=128 scanimage -L" as root. If you don't get any
output from the mustek_pp backend, make sure a line "mustek_pp" is included
into your /etc/sane.d/dll.conf. If your scanner isn't detected, make sure
you've defined the right port address in your mustek_pp.conf.
the name of your scanner/vendor
also a worthy information. Please also include the optical resolution and
lamp type of your scanner, both can be found in the manual of your scanner.
any further comments
if you have comments about the documentation (what could be done better), or
you think I should know something, please include it.
some nice greetings
