1. OVERVIEW
1. OVERVIEW
1.1 Features
600-dpi optical resolution for high-precision image scanning
Scanning with an optical resolution of 600 dpi allows even complex and difcult-to-scan documents,
such as CAD drawings, electronic les, and mapping data to be scanned rapidly and with high precision.
Scanning Master 21+ (scanner software included as a standard accessory) can be used to adjust the
resolution in ve levels (200 dpi to 800 dpi) to suit the scanned document.
Compatible document widths range from 210 mm to 1000 mm
Compatible with document sizes from ISO A4 up to ANSI E
Capable of color and grayscale scanning
Capable of scanning in color (24-bit color, 8-bit color) or grayscale (256 shades)
Capable of reading long-axis data
Long-axis images are supported with a maximum length of approximately four meters each.
Compact and lightweight design
A compact design was achieved by using a document travel system that employs closely-adhered image
sensors in the sensor unit (ve rows arranged in a zigzag pattern).
Image-processing functions
Use of the scanning software provided lets you set image-processing functions for the scanning of a
document.
Interface
The interface conforms to the SCSI-2 standard.

* 1 Documents up to approximately 16 m in length (driver software limitation) can be scanned. However, the actual
document length that can be scanned is limited by the available memory (hard disk or other data storage device)
of the computer to which the scanner is connected, and also by the grade of the medium being scanned.

Operating system: Windows 95/98/Me, Windows NT 4.0, Windows 2000 or later
CPU: Pentium 133 MHz or higher
Memory: 32 MB or more
Monitor: 1024 × 768 pixels, 256 colors or more
Enough disk space to store data
Mouse
SCSI board by Adaptec
Recommended environment
For binary monochrome data
CPU: Pentium 200 MHz or higher
Memory: 64 MB or more
SCSI board by Adaptec (PCI type)
For grayscale data
CPU: Pentium III 550 MHz or higher
Memory: 256 MB or more
Monitor: 1024 × 768 pixels, High Color or higher resolution
SCSI board by Adaptec (PCI type)
For 8-bit color data
CPU: Pentium III 866 MHz or higher
Memory: 512 MB or more
Monitor: 1024 × 768 pixels, True Color or higher
SCSI board by Adaptec (PCI type)
The system conguration should correspond to the recommended specications listed here, in order to ensure the
optimum capabilities of the scanner.
Use with a system conguration below the recommended specications will affect the scanning speed and prevent
the scanner from operating to its specied capabilities.
To edit an A1-size or larger grayscale document with a resolution of 400 dpi or higher, or an 8-bit color document,
you may need more than the recommended memory sizes above. Depending on the type of document, you may not
be able to scan in the document even if you increase the memory size.

3. PREPARING TO OPERATE THE SCANNER
3.1 Assembling the Scanner
Assemble the stand before mounting the scanner unit. Eight bolts and an Allen wrench are provided with the
stand.
(1) Using the four bolts, loosely attach the center bar (3) to side stay R (1) and side stay L (2).

(2)
(3)
Attach the center bar loosely. Tighten the bolts securely after the scanner unit has been mounted on the
stand.

CS2000-UM-251-9370 3-2
3. PREPARING TO OPERATE THE SCANNER
(2) Hold the scanner unit by the side covers on both sides, and mount the scanner so that the positioning
pins on the stand align with the positioning holes on the underside of the scanner. Secure using the four
bolts.
Holding the scanner by the rear part of the top cover may cause damage to the scanner or to the person doing the
installation. Always hold the scanner by the side covers, at the positions indicated by the shaded circles in the fig-
ure below.

(3) Fully tighten the four bolts on the center bar to secure the side stays (see the diagram for step (1)).
(4) Before beginning scanner operation, be sure to remove the plastic sheet from the bottom of the document
hold-down unit. Please refer to Section 8.2 “Document Hold-Down Unit” for the removal and mounting
procedures.

CS2000-UM-251-9370 3-3
3. PREPARING TO OPERATE THE SCANNER
3.2 Connecting the Scanner to a Power Supply
Insert the female plug of the power cord provided into the scanner’s AC line inlet and insert its male plug into
an electrical socket supplying AC voltage.
Check that the scanner’s Power switch remains in the Off position until the connection of both the power cord
and SCSI interface cable has been completed.
Ensure that the scanner’s Power switch is in the Off position.

CS2000-UM-251-9370 3-4
3. PREPARING TO OPERATE THE SCANNER
3.3 Connecting the SCSI Cable
Obtain a SCSI interface cable (optional) that is compatible with the computer to be connected.
Compatible Cables
The cable must have half-pitch pin-type 50-pin connectors.
To connect multiple SCSI devices in a daisy-chain* arrangement, the total cable length must be no longer
than three meters.
Among Graphtec cables, the SC0006 or SC0006 2M model can be used (depending on the shape of the
connector on the computer’s SCSI interface board).
* Daisy-chain: A method for connecting peripheral devices in a ring arrangement
The use of an incompatible cable may cause the scanner to malfunction or damage the interface.
If the cable comes into contact with the document, use the cable clamp provided as a standard accessory to fasten
the cable to the underside of the scanner.
Connection Procedure
(1) Insert one end of the SCSI cable’s into one of the two SCSI connectors on the scanner’s rear panel.
* Firmly insert the cable’s connector into the scanner’s SCSI connector until it locks into place.

CS2000-UM-251-9370 3-5
3. PREPARING TO OPERATE THE SCANNER
(2) If the SCSI cable comes into contact with the document, use the cable clamp provided as a standard
accessory to fasten the cable to the underside of the scanner, at either the left or right side.

(3) Insert the cable’s other end into the computer’s connector.
(4) If this scanner will be a terminal within the network conguration, set Bit 4 of the DIP switch on the
scanner’s rear panel to enable the internal terminator function.

3. PREPARING TO OPERATE THE SCANNER
3.4 Setting the ID Number
The SCSI bus is designed to allow up to eight devices to be connected at the same time. As a result, a single
computer can be used to exchange data with multiple SCSI devices, including a scanner and disk drives.
Each device must be assigned an ID number (device number) to enable the devices to be distinguished on
the SCSI bus.
Using a mechanical pencil or other pointed object at the SCSI-ID switches on the scanner’s rear panel, set
the scanner’s ID number that corresponds to the host computer’s applications.

1
• The ID can be set from 0 to 7.
• The scanner’s default ID number is 2.
If the host computer cannot communicate with the scanner, rst check that both of the SCSI cable’s
connectors are rmly inserted. Note that the host computer and scanner cannot communicate if the scanner
shares the same ID as another device or its ID does not correspond to the host computer’s applications.
The ID number for the host computer is normally 7.
Turn off the scanner before setting the SCSI-ID number.
The scanner comes with the default SCSI-ID number of 2.

CS2000-UM-251-9370 3-7
3. PREPARING TO OPERATE THE SCANNER
3.5 Turning the Scanner On or Off
Whenever the scanner’s Power switch is turned on, the POWER, PAPER, and ERROR lamps on the control
panel light up. When the scanner has been initialized, the POWER lamp lights up.
When resetting the scanner by turning it off then back on again, wait at least three seconds before turning it back
on.
3.6 Attaching the Document Support Wires
The document support wires should be attached when carrier sheets or heavy documents are scanned.
Document support wires

CS2000-UM-251-9370 3-8
3. PREPARING TO OPERATE THE SCANNER
Attaching the document support wires
(1) Insert one end of the document support wire provided into the slot at the rear of the scanner.
(2) Squeeze the document support wire, and insert the other end.
(3) Press down on both sides of the document support wire.
(4) Attach the other document support wires in the same manner.
Detach the document support wires when moving or packing the scanner. Squeeze softly and lift them to detach.
