sane-hs2p - SANE backend for Ricoh SCSI flatbed/ADF scanners
|
||
|
||
|
||
</PRE>
|
||
<H2>DESCRIPTION</H2><PRE>
|
||
The <B>sane-hs2p</B> library implements a SANE (Scanner Access Now Easy) back‐
|
||
end that provides access to the Ricoh IS450 family of scanners. Should
|
||
also work with the IS420, IS410, and IS430 scanners, but these are
|
||
untested. Please contact the maintainer or the sane-devel mailing list
|
||
if you own such a scanner.
|
||
|
||
This backend is alpha-quality. It may have bugs and some scanners
|
||
haven't been tested at all. Be careful and pull the plug if the scanner
|
||
causes unusual noise.
|
||
|
||
|
||
</PRE>
|
||
<H2>DEVICE NAMES</H2><PRE>
|
||
This backend expects device names of the form:
|
||
|
||
<I>special</I>
|
||
|
||
Where <I>special</I> is either the path-name for the special device that cor‐
|
||
responds to a SCSI scanner. The program <I>sane-find-scanner</I> helps to find
|
||
out the correct device. Under Linux, such a device name could be
|
||
<I>/dev/sg0</I> or <I>/dev/sga</I>, for example. See <B><A HREF="sane-scsi.5.html">sane-scsi(5)</A></B> for details.
|
||
|
||
|
||
</PRE>
|
||
<H2>CONFIGURATION</H2><PRE>
|
||
The contents of the <I>hs2p.conf</I> file is a list of device names that cor‐
|
||
respond to SCSI scanners. Empty lines and lines starting with a hash
|
||
mark (#) are ignored. See <B><A HREF="sane-scsi.5.html">sane-scsi(5)</A></B> on details of what constitutes
|
||
a valid device name.
|
||
|
||
|
||
</PRE>
|
||
<H2>FILES</H2><PRE>
|
||
<I>/usr/local/etc/sane.d/hs2p.conf</I>
|
||
The backend configuration file (see also description of
|
||
<B>SANE_CONFIG_DIR</B> below).
|
||
|
||
<I>/usr/local/lib/sane/libsane-hs2p.a</I>
|
||
The static library implementing this backend.
|
||
|
||
<I>/usr/local/lib/sane/libsane-hs2p.so</I>
|
||
The shared library implementing this backend (present on systems
|
||
that support dynamic loading).
|
||
|
||
|
||
</PRE>
|
||
<H2>ENVIRONMENT</H2><PRE>
|
||
<B>SANE_CONFIG_DIR</B>
|
||
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 config‐
|
||
uration file is searched in two default directories: first, the
|
||
current working directory (".") and then in
|
||
/usr/local/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 directo‐
|
||
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
||
would result in directories "tmp/config", ".", and
|
||
"/usr/local/etc/sane.d" being searched (in this order).
|
||
|
||
<B>SANE_DEBUG_HS2P</B>
|
||
If the library was compiled with debug support enabled, this
|
||
environment variable controls the debug level for this backend.
|
||
A value of 255 prints all debug output. Smaller values reduce
|
||
verbosity.
|
||
|
||
|
||
</PRE>
|
||
<H2>CURRENT STATUS</H2><PRE>
|
||
The hs2p backend is now in version 1.00. All major scanning-related
|
||
features are supported, except for those features requiring the
|
||
optional IPU. Scanning from the flatbed or ADF (either simplex or
|
||
duplex) is supported. Lineart, halftone, 4-bit gray, and 8-bit gray are
|
||
supported. Pre-set gamma tables and halftone patterns are supported, as
|
||
well as brightness, threshold, contrast. Also supported is scan wait
|
||
mode, binary and gray filtering, negative scanning, and absolute or
|
||
relative white setting. Printing with the optional endorser also is
|
||
supported.
|
||
|
||
|
||
</PRE>
|
||
<H2>PLANNED FUNCTIONALITY</H2><PRE>
|
||
This scanner can scan from the ADF in continuous simplex mode. Sur‐
|
||
prisingly, many scanners scan an entire document from the ADF into mem‐
|
||
ory before ejecting the sheet. Thus if the document is too long, the
|
||
scanner cannot hold the entire image data in memory. But if the scan‐
|
||
ner would send its image data when its memory got full, and then read
|
||
the next buffer's worth of data, continuous scanning could be achieved.
|
||
|
||
|
||
</PRE>
|
||
<H2>MISSING FUNCTIONALITY</H2><PRE>
|
||
The SCSI commands for uploading (2AH) or downloading (28H) custom
|
||
halftone patterns (02H) and gamma vectors (03H) should work, but
|
||
require implementing the SANE Option-Value code to allow the user to
|
||
create the tables to be uploaded to the scanner. No support for Mainte‐
|
||
nance Data (80H) is planned as this functionality is more suited to a
|
||
stand-alone utility to be used by a technician when replacing the lamp
|
||
or ADF unit. Nor is support for reading or changing IPU (93H) parame‐
|
||
ters and adjustments planned, since my IS450 lacks such a unit. The
|
||
31-byte Auto Photo/Letter struct and 21-byte Dynamic threshold struct
|
||
are documented in the hs2p-scsi.h file should someone wish to use their
|
||
IPU for image data processing.
