¥ Terminator Settings
The terminator marks the last device in a daisy chain. It tells the computer that Òthis is the
last deviceÓ. There are two types of terminator: a separate device that is attached to a SCSI
device or an On/Off switch built into the SCSI device. This scanner has a built-in terminator.
For a daisy chain to operate correctly, the terminator must be set to On for the last SCSI
device , and Off for all other SCSI devices. A typical daisy chain is shown below.

WARNING¥ The SCSI ID does not have to follow the order of connection. As long as an ID is not
repeated, IDs between 0 and 6 can be used.
¥ SCSI device equipped computers usually have the following SCSI ID already assigned.
(Read the manual for each computer or SCSI card.) Assign an unused SCSI ID to this
scanner.
- For Windows
7: SCSI card or internal SCSI controller
- For Macintosh
0: Internal hard disk drive
3: Internal CD-ROM drive (Desktop model with an internal CD-ROM drive)
7: Macintosh CPU
¥ Ensure that you unplug the AC adapter from the scanner before you change the SCSI ID or
terminator settings. After resetting them, reconnect the AC adapter and restart the computer.
¥ How to Set the SCSI ID and Terminator
To set the SCSI ID and terminator on this scanner, adjust the dip switches found on the back
panel of the scanner.

To set the SCSI ID, move the 1-3 switches with a sharp object, such as the tip of a
mechanical pencil. Set the switch positions as below to assign a SCSI ID from 0 to 6.
To set the terminator ID, move the switch labeled 4. As shown below, the terminator is Off
when the switch is set to the upper side, and On when it is to the lower side.
The SCSI ID is set to 2 and the terminator is On when this equipment is shipped from the factory.

SCSI Connector and SCSI Interface Cable Descriptions
This scanner is equipped with both a Half Pitch 50-Pin and D-Sub 25-Pin connector (port).
The supplied SCSI interface cable has a Half Pitch 50-Pin connector on one end and a D-Sub
25-Pin connector on the other.
There are many other types of SCSI connector on the market. When choosing a SCSI cable,
you must match the connector shapes, the SCSI cable standard and the impedance category.
Without all three correctly matched at both the computer and SCSI device ends, the
connection will not work. Check your computerÕs SCSI connector to make sure it fits the
supplied SCSI interface cable. If it doesnÕt, purchase a SCSI interface cable (high-impedance)
with connectors that fit into the connectors on your computer and scanner.

WARNING¥ The Half Pitch 50-Pin and Centronics Half Pitch 50-Pin connectors look alike and the sizes
are similar. However, close examination reveals that the pin shapes are different. Be
careful when purchasing.
¥ Only high-impedance cables work with the scanner. Ensure that cables other than the
supplied SCSI interface cable are of the high-impedance type.

Positioning Documents (No ADF)
Documents must be placed on the document glass to be scanned. The instructions below are for manual
positioning. If you are using the automatic document feeder (ADF) option, please see Chapter 3.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
1. Lift the document cover.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
2. Place the document face down.
Orient the document face down on the document glass with the top edge at the back of
the scanner (the edge closest to the hinges of the document cover). Align the edges of the
document with the alignment mark.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
3. Close the document cover, being careful not to dislodge the document.

WARNING¥ The maximum allowable size for scanning is 216 x 297 millimeters (8.5 x 11.69 inches), up
to A4 or Letter size.
¥ This scanner is equipped with an ultra-sensitive scanning unit. Opening the document
cover during scanning, or improperly closing it, may affect the scanning results. If you are
scanning thick documents, such as books, that prevent the document cover from closing,
cover the document glass with a dark cloth to prevent ambient light from affecting the
scan.
