NAME
sane-mustek_pp - SANE backend for Mustek parallel port
flatbed scannersDESCRIPTION
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: regu-
lar 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: CCD scanners Model: ASIC ID: CCD Type: works:____________________________________________________

(**) Problems have been reported in the past for theMD/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 prob-
lems. IF YOU HEAR LOUD CLICKING NOISES, (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 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. EPP mode however may lead to hard-locks on some Linux
systems. If that is the case for you, you can either disableECP/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 sup-
port parport sharing, i.e. if you try printing while scan-
ning, your computer may crash. To enable parport sharing, you have to enable libieee1284 at compile time. This backendalso 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, justremove the hash mark in the line "mustek_pp".
DEVICE DEFINITIONThis backend allows multiple devices being defined and con-
figured via the mustek_pp.conf file (even simultaneously,
provided that they are connected to different parallel ports). Please make sure to edit this file before you use the backend. SunOS 5.10 Last change: November 17 2003 2Standards, Environments, and Macros sane-mustek_pp(5)
A device can be defined as follows: scannerwhere is an arbitrary name for the device, optionally enclosed by double quotes, for instance "LifeTec 9350". 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 dif-
ferent 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 yourport. 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.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 Especially, using the 1200CP settings on a 600CP can be harmful. If the scanner starts making a loud noise, 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 typi-
cally 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 SunOS 5.10 Last change: November 17 2003 3Standards, Environments, and Macros sane-mustek_pp(5)
resolution of 600x1200 DPI. Examples: scanner "LifeTec 9350" 0x378 cis1200scanner Mustek_600CP 0x378 cis600
scanner Mustek_600IIIEP * ccd300
If in doubt which port you have to use, or whether yourscanner is detected at all, you can use sane-find-scanner -p
to probe all configured ports. CONFIGURATIONThe 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[ ] Depending on the nature of the option, a value may or may not be present. Options always apply to the scanner defini-
tion that precedes them. There are no global options.Options are also driver-specific: not all drivers support
all possible options. Common options bwBlack/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
Vertical adjustment of the origin, expressed in millim-
eter (floating point). This option can be used to cali-
brate the position of the origin, within certain lim-
its. 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. SunOS 5.10 Last change: November 17 2003 4Standards, Environments, and Macros sane-mustek_pp(5)
Default value: 0.0Minimum: -5.0
Maximum: 5.0Example: option top_adjust -2.5
slow_skip
Turns fast skipping to the start of the scan regionoff. When the region to scan does not start at the ori-
gin, 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 inaccu-
racy problems are known to occur. By default, fast skipping is used.Example: option slow_skip
engine_delay
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 reliabledetection of the engine state. As a result, engine com-
mands 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, theengine_delay option can be set. If it is set, the
driver waits an additional amount of time after everyengine 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. Note that every additional ms of delay can add up to 14seconds to the total scanning time (highest resolu-
tion), so an as small as possible value is preferred. Default value: 0 Minimum: 0 Maximum: 100Example: option engine_delay 1

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 SunOS 5.10 Last change: November 17 2003 7Standards, Environments, and Macros sane-mustek_pp(5)
directories are searched after the explicitly specifieddirectories. 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. level debug output- -

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 versionrun "scanimage -V" to determine this
the backend version and your scannerrun "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 yourmustek_pp.conf.
the name of your scanner/vendoralso a worthy information. Please also include the opt-
ical 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 (whatcould be done better), or you think I should know some-
thing, please include it. some nice greetingsATTRIBUTES
