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.

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

CS2000-UM-251-9370 3-6

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.

• 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.

4.5 Loading a Document

For standard-size documents

Insert the document into the document-scanning table with the face to be scanned facing downward, so that

it is aligned with the center section, to ensure that it is not scanned at an angle. The two modes described

below are provided for loading the document (set from the driver software).

The rollers start rotating after a preset delay time after the document is inserted, to automatically advance

the document to the initial position for scanning.

The rollers start rotating when the FORWARD switch is pressed on the control panel after the document is

inserted, to automatically advance the document to the initial position for scanning (manual loading).

To reposition the document, press the REVERSE switch to remove it, and load it again.

If the PAPER LED does not light after the document feed operation has stopped, press the FORWARD key to ad-

vance the document again.

After the CS2000 is turned on and the driver settings have been enabled in the Scan window, it waits for approxi-

mately two seconds before beginning the specied scan operation.

Load the document in the scanner with the face to be scanned facing downward.

Do not place anything other than the document to be scanned on the scanning table, as the scanner rollers may

start rotating, which is extremely dangerous.

The document may not be fed in correctly if it is curled. The carrier sheet provided should be used for curled docu-

ments (see “4.7 Using the Carrier Sheet” for details).

Load the document in the center of the scanner, as the document may be fed in at an angle and not scanned cor-

rectly if it is signicantly off-center.

4.7 Using the Carrier Sheet

Use the carrier sheet according to the condition of the document to be scanned.

In the case of scanning the following types of media, always place the document on the carrier sheet before

loading it into the scanner.

To scan a medium that is as limp as or limper than a newspaper

To scan paper that is badly curled

To scan a document that is smaller than A4 size or a document of non-standard size

To scan a medium that tears easily

When the target document cannot be properly advanced to the initial position of scanning (because the

target document is folded, wrinkled, or otherwise hard to load in the scanner)

To scan transparent or translucent documents

As shown in the gure below, place the document in the carrier sheet with the document’s surface to be

scanned facing up (against the transparent top sheet). For scanning, load the carrier sheet into the scanner

with the document’s target surface (the transparent top sheet) facing down.

When handling the carrier sheet, be very careful not to scratch it or otherwise damage it.

CS2000-UM-251-9370 5-1

CS2000-UM-251-9370 5-2

5. DAILY MAINTENANCE

Mounting the Document Hold-Down Unit

(1) While holding the document hold-down unit by the handle-ring at each side, lower the document

hold-down unit straight down into the scanner.

(2) Push down the handle- rings on each side of the document hold-down unit.

(3) Close the top cover, holding it in the center.

The document hold- down unit has a symmetrical shape, so it is physically possible to mount it with its right and left

sides reversed. Because the scanner’s precision has been adjusted before shipment from the factory, however, its

reading precision will decrease extremely if you mount the document hold - down unit in reverse.

Before mounting the document hold-down unit, be sure to check its proper orientation as indicated on the seals at-

tached to the scanner and the document hold-down unit.

Fully insert the document hold-down unit to the bottom end. If the document holddown unit is not pressed down,

this will result in reduced image quality and paper jamming.

10.3 Preparing a Test Chart

(1) Prepare a CS1000 adjustment test chart.

(2) Make sure that the distances (measured with a glass scale) between the two points in all pairs are

included in the chart in advance. (See the chart shown above.)

<<Tip 1>> Test chart is made of Mylar paper.

For use in normal ofce environments (normal temperatures and humidity levels), you should

only need to measure each distance once.

Make sure that each distance is measured with the utmost accuracy.

<<Tip 2>> Make sure that all staff members using this test chart select the same measurement points.

This chart has been designed with the assumption that the point shown below is used for

measurement.

<<Tip 3>> If the user-specied paper must be used for adjustments, you should make the measurements

over as long a period of time as possible to obtain good results.

The scanned data is displayed when scanning is complete. Colors may differ slightly for individual

sensors to make it easier to identify problem areas in calibration. This does not indicate a defect.

Check that there are no vertical streaks, such as white patches, in the scanned data.

(Streaks occur when calibration is not performed correctly due to contamination by dust or dirt.)

(8) If the data is normal, calibration is complete.

Click the Close button and exit calibration mode.

(9) If any abnormal data is observed, specify the problem areas as follows:

Select Specied Part in Calibration.

(10) The mouse arrow cursor changes to a cross cursor when moved over the data. Click the left mouse

button with the mouse positioned over the streak data. The selected area is shown in blue. Repeat this

procedure for any additional streaks.

Areas that have been selected (shown in blue) can be deselected by clicking the left mouse button again.
