IMPORTANT SAFETY INSTRUCTIONS

When using the Slide Scanner, basic safety precautions should always be followed including the

following:

• Read and understand all instructions before using.

• Position the cord so that it will not be tripped over, pulled, or contact hot or sharp surfaces.

• If an extension cord is necessary, a UL recognized grounded cord with a rating at least

equal to that of the slide scanner should be used. Extension cords rated for less amperage

may overheat. Connect the slide scanner to a grounded outlet.

• Always turn the host computer OFF and then the slide scanner OFF before unplugging.

• Always unplug the slide scanner from the electrical outlet before cleaning and servicing and

when not in use. Never pull the cord from the outlet. Grasp and pull the plug from the outlet

to disconnect.

• Do not disassemble the slide scanner, but take it to a qualified service person when service

or repair work is required. Incorrect assembly can cause electrical shock when the slide

scanner is used subsequently.

Description

This section of the Repair Manual gives an overview of the SprintScan 35, the SprintScan 35

ES, and the SprintScan 35 PLUS slide scanner. It only provides the necessary information

pertaining to features and specifications for each slide scanner.

For detailed information pertaining to setting up the slide scanner, installing and starting their

software, assigning SCSI ID's and checking SCSI connections, scanning transparencies, and

using application software, refer to the applicable slide scanner User Guide.

capable of scanning positive and negative media, mounted and unmounted transparencies and

unmounted transparency filmstrips.

Each system (Figure 1-1) consists of a:

• Slide Scanner

• Power Cord

• SCSI cable with 25-pin and 50-pin connector ends

• SCSI terminator (Supplied only with SprintScan 35 ES)

• SprintScan software diskette

• Adaptec AT-to-SCSI Host Adapter with EZ-SCSI Lite application diskette and

documentation (Windows version only)

• Adobe PhotoDeluxe CD (Mac/Windows)

• Filmstrip carrier for negative strip or unmounted slide film

Features

Table 1-2 list and describes the features of the slide scanners (Figure 1-2).

Table 1-2. Slide Scanner Features

Feature Description

Power LED Indicator This green LED indicator lights to indicate when the

slide scanner power is turned on.

Note: During power-up the slide scanner initiates its

self-test mode.

Ready LED Indicator This yellow LED indicator lights to indicate when the

slide scanner is ready to operate (passed power up

self-test).

Notes: • This indicator continually blinks while the

slide scanner cycles through its self-test.

• Upon completion, this indicator lights steady

to indicate that the slide scanner is ready to

operate.

Top Access Slot The top access slot is used when scanning 35 mm slide

transparencies.

Side Access Slot The side access slot is used when scanning unmounted

slides and 35 mm filmstrips using the filmstrip carrier

included in the accessory kit.

Filmstrip Carrier Included with the accessory kit.

Used to scan a 35 mm negative strip or an unmounted

slide. Supports 35 mm filmstrips from 1 - 6 frames.

Release Button This button is used to release the front cover when

replacing the lamp. (Spare lamp located inside front

cover.)

Power On/Off (1/0) Switch This switch turns the slide scanner power on or off. The

Table 1-2. Slide Scanner Features (Cont'd)

Feature Description

Power Receptacle Standard receptacle with ground.

Power Cord Standard cord with ground.

Power Fuse Receptacle The fuse receptacle contains two fuses: active and

(SS35 Only) spare.

The active fuse protects the slide scanner's electronics

from any sudden surges or overloads.

Note: If the active fuse fails (blows), always attempt to

find out the cause of the malfunction before

replacing the blown fuse with the provided spare.

Replace the spare fuse with a new one as

soon as possible.

Power Fuse Not user accessible. Located on power supply PC

(SS35 PLUS) board.

SCSI ID Selector/Indicator The slide scanner's SCSI ID is preset at the factory

to 6.

SCSI ID position 7 is reserved for the SCSI adapter to

which the SCSI device(s) are connected.

Note: DO NOT change this value unless other SCSI

devices are attached to the slide scanner and

one of them is assigned to SCSI value 6.

If the preset SCSI value must be changed, refer

to the applicable slide scanner User's Guide for

detailed instructions on how to change the slide

scanner's SCSI value.

Slide Scanner Repair Manual Scanner Overview

Table 1-2. Slide Scanner Features (Cont'd)

Feature Description

SCSI Receptacles SS35/SS35 ES: (Top and Bottom)

Two (2) 50-pin standard SCSI receptacles.

SS35 PLUS:

One (1) 50-pin standard SCSI receptacle.

One (1) 25-pin standard SCSI receptacle.

SCSI Cable This cable (25-pin and 50-pin connector ends) connects

theslide scanner to the host computer.

Note: The 50-pin end of the SCSI cable connects to the

top SCSI receptacle. The 25-pin end of the SCSI

cable connects to the 25-pin SCSI port at the

rear of the host computer (Adaptec AT-to-SCSI

Host Adapter port for Windows version).

SCSI Terminator SS35/SS35 ES:

SCSI terminator connects to the bottom receptacle.

SS35 PLUS:

SCSI terminator built in. To activate SCSI terminator,

set SCSI terminator switch to its ON position.

Notes: • To function properly, a SCSI chain must be

terminated at each end.

• The Adaptec AT-to-SCSI Host Adapter for

Windows version is internally terminated, which

means that it is the first one of the required

terminators.

• If the slide scanner is the only SCSI device to

be connected to the host computer, connect the

SCSI terminator to the bottom SCSI receptacle.

For SS35 PLUS turn on the terminator switch.

Feature Description

SCSI Terminator

(Cont'd) Warning: If the slide scanner is being added to an

existing SCSI device chain, make sure that

only two SCSI terminators (internal or

external) exist in the SCSI device chain.

More than two SCSI terminators in the SCSI

device chain can damage the host computer

or the devices.

Adaptec AT-to-SCSI This adapter provides the interface through which the

Host Adapter slide scanner and host computer communicate.

(Windows Version ONLY)

Notes: • The adapter is preset at the factory for default

interrupts and port address values.

• Host adapter not included with all models

EZ-SCSI Lite Software Included with the Adaptec AT-to-SCSI Host Adapter.

(Windows Version ONLY)

This software application is used to configure the host

computer for the SCSI adapter. It also provides

additional driver files for the SCSI interface.

Notes: • The host computer must always be restarted

after the EZ-SCSI Lite software is installed.

• If necessary, contact Adaptec for latest version

drivers. Drivers can be downloaded from

Adaptec's website at:
