Preface
The Contex Full Scale Monochrome Scanners provide a complete
solution for scanning drawings, documents and pictures for use with
CAD, DTP, COPY and Drawing Archival applications.
The built-in dedicated high-speed Digital Signal Processor (DSP)
performs image processing and enhancement in real time.
The fast industry standard SCSI I/F and WIDEimage software makes
the Full Scale Scanner truly multi-platform.
The WIDEimage scanning software is available in Windows-98,
Windows SE, Windows ME, Windows 2000 and Windows NT4.0
editions for PCs.
This guide explains how to operate and maintain the Full Scale
Scanner. It assumes a basic knowledge of your computer and
operating system and does not repeat material from their
documentation.
SYSTEM REQUIREMENTS
• WIDEimage scanning software
• PC that fulfils WIDEimage’s minimum requirements
• SCSI interface kit matching your workstation.

1. Introduction
The Contex Full Scale Scanner x300 models: FSS18300DSP,
FSS12300DSP, FSS8300DSP, FSS8300PLUSDSP and FSS4300DSP are
monochrome scanners and their drawing width size and resolution
ranges vary as follows:
• FSS18300DSP: E-Size(A0) scanning width and up to 1800 dpi
resolution.
• FSS12300DSP: E-Size(A0) scanning width and up to 1200 dpi
resolution.
• FSS8300DSP : E-Size(A0) scanning width and up to 800 dpi
resolution.
• FSS8300PLUSDSP: E-Size(A0) scanning width and up to 800 dpi
resolution. Very high scanning speed. The resolutions can be set
in 1 dpi increments. Includes Area Diffusion Logic (ADL).
• FSS4300DSP: E-Size(A0) scanning width and up to 400 dpi
resolution.
The Full Scale Scanner line is produced by Contex, the leading
manufacturer of large format scanners, with many thousands of
installations world-wide.
The Full Scale Scanners are designed to work with all types of
technical scanning applications.

1.1 Computer Aided Design
The Full Scale Scanners (FSS) offer CAD-Systems users easy access
to architectural, civil and mechanical drawings, bridging the gap
between CAD and hard-copy drawing media.
The FSS with its WIDEimage program scans hard-copy originals
directly into the workstation. Formats up to E-Size(A0) can be
scanned, allowing you to capture drawings for modification, storage, or
transmission, or to bring hard-copy drawings on-line.
The FSS scans original line art, maps, blueprints, sepias, vellum and
mylar drawings in high resolution. The Full Scale Scanners have a
built-in white, spring-loaded background pressure platen to support
scanning of transparent originals.
The unique two-dimensional 2D-Adaptive Thresholding and built-in
high-speed Digital Signal Processor provides clean crisp scans from
poor quality drawings on-line, without the need for pre-scan. It

automatically adapts to the drawing, compensating for varying
background, faded areas and stains.
CAD-systems such as AutoCAD, VersaCAD, etc., can make full use of
the Full Scale Scanners, either directly or together with raster-editors,
archiving, overlay or raster-to-vector conversion programs. The FSS is
a time saving way to capture the machine-drawn or hand-drawn
originals onto an electronic medium.
1.2 Copying
Using the FSS and WIDEimage with a laser printer provides an
inexpensive and convenient way to transform any large format
technical drawing into standard-sized copy for enclosure in reports or
documentation; or you can output them to an inkjet or laser plotter for
a full size copy.
1.3 Desk Top Publishing Systems
With the FSS you can now scan originals of almost any size into the
computer so their images can be included in technical documents,
user manuals, sales brochures, spare parts catalogues, proposals,
bids, etc., using popular desk top publishing applications such as
Aldus PageMaker or Ventura Desk Top Publisher.
Through WIDEimage the FSS is compatible with most software and
standard DTP file formats. The FSS Window Scan feature allows you
to cut and crop areas of interest out of larger drawings.
With its ease of use and flexibility regarding original sizes and file
formats, the FSS is the scanner of choice for the technical publishing
office.

1.4 Drawing Archival and Management
Many of an organization's resources are held in its archives. Electronic
Drawing Management Systems allow on-line access and control of
vital company assets such as scanned mechanical drawings, electrical
schematics and facility plans on hard- or optical disks.
A single CD-ROM can store 800 to 1000 E-Size drawings, meaning
that your archives could contain several hundreds of thousands of
drawings.
Electronically accessing, viewing, modifying, converting and printing or
plotting your drawings saves you time and money.
The FSS supports the Computer Acquisition and Logistics (CALS) and
ISO-ODA standard CCITT Group4 (MIL 28002) drawing archival
formats.
1.5 Satellite Photo Scanning
Use the Full Scale Scanners’ graytone scanning capability of 256
levels, together with applications like CADOverlay GS, to directly
overlay satellite photos in AutoCAD, with image correction facilities.

mm), by graytone interpolation and re-sampling of the physical
32.000 pixels (four cameras).
• FSS12300DSP: Up to 1200 dpi scan resolution at all original sizes;
43.200 dots at 1200 dpi, scanned at the max. scan width 36" (914
mm), by graytone interpolation and re-sampling of the physical
24.000 pixels (three cameras).
• FSS8300DSP: Up to 800 dpi scan resolution at all original sizes;
28.800 dots at 800 dpi, scanned at the max. scan width 36" (914
mm), by graytone interpolation and re-sampling of the physical
16.000 pixels (two cameras).
• FSS8300PLUSDSP: Up to 800 dpi resolution, setable in 1 dpi
increments, at all original sizes; 28.800 dots at 800 dpi, scanned
at the max. scan width 36" (914 mm), by graytone interpolation
and re-sampling of the physical 16.000 pixels (two cameras).
• FSS4300DSP: Up to 400 dpi resolution at all original sizes; 14.400
dots at 400 dpi, scanned at the max. scan width 36" (914 mm), by
graytone interpolation and re-sampling of the physical 8.000
pixels (one camera).
• Connection to the computer via standard SCSI Interface
• Scanning area sized from A5 up to A0 and E-Size (from 152 mm
up to 914 mm wide). Media size: 152 to 1016 mm.
• Image processing and enhancement options include: 2D-
Adaptive thresholding, histogram analysis, and on-line threshold
variation.
• On-line de-skewing and de-speckling, during simultaneous
scanning of the drawing, producing perfectly horizontally aligned
and speckle-free scans.
