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 specied 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 signicantly off-center.

5.1 Removing and Mounting the Document Hold-Down Unit
To clean the scanner, you must rst remove the document hold-down unit. It is also necessary to remove the
document hold-down unit to remove a jammed document.
Removing the Document Hold- Down Unit
(1) Turn off the scanner.
(2) Open the top cover, holding it in the center.
(3) From inside the scanner, lift up the handle-rings provided at each side of the document hold-down unit in
order to lift the document hold-down unit up and off.
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.

taining alcohol.
CS2000-UM-251-9370 5-5
5. DAILY MAINTENANCE
Although the glass scanning table is not a maintenance part that requires periodic replacement, it is a consumable
part because its surface may receive slight scratches due to minute particles of dust and other foreign matter. If
document scanning produces unsatisfactory results (unexpected white or black streaks in the data) due to scratch-
es on the glass table or other reasons, please perform the calibration procedure (see Section 10.4, “1. Calibration”).
If the scanning results do not improve after calibration, the glass table will need to be replaced.

8.1 Considerations before starting disassembly
To prevent damage to image sensors, remove the document hold-down unit before disassembling any
mechanical parts.
Removing screws and any parts other than those shown in this chapter may adversely affect scanner
performance, including degraded scanning accuracy.
In particular, never attempt to remove or turn the red shielded screws and height adjustment screws.
The directions "left" and "right" given in this chapter assume that the scanner unit is viewed from the
front.
