2. INSTALLATION

Please unpack the scanner carefully, and check the contents
against the checklist. If any items are missing or
damaged, please contact your authorized local dealer
immediately.

Precautions

• Keep the scanner out of direct sunlight. Direct
exposure to the sun or excessive heat may cause
damage to the unit.

• Do not install the scanner in a humid or dusty place.

• Use only the AC adapter (HEG42-240200-7L by

Hitron) included with the machine. Using other AC
adapters may damage the machine and void the
warranty.

• Place the scanner securely on an even, flat surface.
Tilted or uneven surfaces may cause mechanical or
paper-feeding problems.

• Retain the scanner box and packing materials for
shipping purposes.

2.1 UNLOCKING THE SHIPPING SWITCH

The scanner has a shipping switch that locks the carrier
mechanism for transportation purposes. This switch must
be unlocked before using the scanner.

Before proceeding, turn the power off, disconnect all cables
and follow the instructions below to unlock the shipping
switch.

2-1

2.1.1 UNLOCKING THE SCANNER

i). Carefully place the scanner in an upright

position on its front.

ii). Unlock the scanner by moving the lock switch beneath

the scanner to the “Unlock” position (See Figure 2-1).

iii). Gently place the scanner back to its normal position.

Figure 2-1 Unlocking the Shipping Switch

2-2

2.1.2 LOCKING THE SHIPPING SWITCH

Whenever you need to move the scanner to a new location
it is advisable to lock the shipping switch to avoid causing
damage to the scanners’ internal mechanism. Please follow
the instructions below to lock the shipping switch.

1). Turn off the scanner.

2). Lift the Document cover to reveal the flatbed glass and

scanning unit.

3). Turn on the scanner.

4). Turn off the scanner again while the scanning unit

moved to the end for a few seconds.

side.

6). Lock your scanner by moving the lock switch to the

"Locked position".

7). Place the scanner back to its normal position.

2-3

2.2 SCSI ID

When you have several devices on a SCSI chain, you may
need to adjust the SCSI ID selector setting located on the
back of the scanner. This setting assigns a specific "device
ID" to the scanner. If the assignment conflicts with an
existing SCSI device, please select a new ID. (See Figure 2-

2)

Note: The factory setting for scanner is ID 6. Usually, ID 0
is assigned to an internal hard disk drive, and ID 7, ID 8 ,and
ID 9 are not in actual use.

Using a suitable tool, turn the selector switch until the arrow
points to the desired ID number.

2.3 Setting SCSI Terminator

The scanner is equipped with a built-in terminator switch on
the rear of the scanner. (See Figure 2-2). The scanner is
equipped with a built-in terminator switch on the rear of the
scanner. Turn the terminator switch on if the scanner is to be
connected to the computer as the only or the last SCSI
device. Turn the terminator switch off if the scanner is to be
located between the computer and the other SCSI device.
