NAME

DESCRIPTION

There are 2 classes of Mustek parallel port scanners: regular CCD (cold cathode device) scanners and CIS (contact image sensor) scanners.

Previous versions of this backend only supported CCD type scanners. Patches for CIS type scanners were available, but simultaneous support for both types was not possible. The current version of the driver enables both types to co-exist. The CIS drivers have been ported to it already, and work is going on to port the CCD drivers too.

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).

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).

Some scanners work faster when EPP/ECP is enabled in the BIOS.

Note that the backend needs to run as root. To allow user access to the scanner run the backend through the network interface (See saned(1) 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. This backend also conflicts with the sane-musteka4s2 backend. You can only enable one of them in your dll.conf. However, you have to enable the backend explicitly in your dll.conf, just remove the hash mark in the line "mustek_pp".

DEVICE DEFINITION

A device can be defined as follows:

scanner <name> <address> <driver>

where

<name>

is an arbitrary name for the device, optionally enclosed by double quotes, for instance "LifeTec 9350".

<address>

is the port address of the parallel port to which the device is connected. Known ports are 0x378, 0x278, and 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 /etc/conf.modules, /etc/modules.conf and/or /proc/ioports.

<driver>

is the driver to use for this device. Currently available drivers are:

cis600 : for 600 CP & OEM versions
cis1200 : for 1200 CP & OEM versions
cis1200+ : for 1200 CP+ & OEM versions

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 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.

Examples:

scanner "LifeTec 9350" 0x378 cis1200

scanner Mustek_600CP 0x378 cis600

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 preceeds 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_skip -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 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.
By default, fast skipping is used.

Example: option slow_skip

CCD driver options

To be defined.

A sample configuration file is shown below:

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

   # Some calibration options (examples!).

   option bw 127

   option top_skip -0.8

#
# A Mustek 600CP on port 0x3BC
#
scanner "Mustek 600CP" 0x3BC cis600

   # Some calibration options (examples!).

   option bw 120

   option top_skip 1.2

#
# A Mustek 1200CP+ on port 0x278
#
scanner "Mustek 1200CP plus" 0x278 cis1200+

   # Some calibration options (examples!).

   option bw 130

   option top_skip 0.2

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 support 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_CONFIG_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.

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 million lines of debug output.

* 1015 only works for CCD type 00 & 01 (01 only bw/grayscale)

BUG REPORTS

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
