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.

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.

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
th eslide 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.

Slide Scanner Repair Manual Scanner Overview
Self-Check Routines
The slide scanner provides two internal self-check software routines that are used to
automatically check (verify) its operation. The two internal self-check software routines are:
• Self-Test (Power-Up)
• Calibration
Self-Test (Power-Up) Routine
When the slide scanner is turned on, the self-test (power-up) routine is automatically invoked.
This routine checks and verifies the following operations:
• Initializes all system electronics (image sensor and main controller PC boards).
• Finds calibration window (Transporter moves shutter to its calibration window
position and stops.)
Note: If the calibration window position can not be found, the transporter moves
to its top position and then returns the shutter to what it thinks is the correct
position.
Refer to the simplified flow diagram shown in Figure 1-7 for the necessary steps to self-test the
slide scanner during power-up.
Upon completion (passed self-test), the transporter returns to its home position and the Ready
LED lights steady to indicate that the slide scanner is ready to operate.
Notes: • If the yellow Ready LED continually blinks, the slide scanner failed its self-test.
Run the LabVIEW IPT test to determine why the slide scanner failed its
self-test . (Refer to the applicable LabVIEW test in Section 5 of this Repair
Manual for detailed instructions on how to run the LabVIEW test procedure.)
• If the yellow Ready LED does not light after the self-test is performed, turn off
the slide scanner (power-down), wait approximately 10 seconds and then
power-up again.
Causes of self-test (power-up) failure are usually due to a defective EEPROM, incorrect
EEPROM data, the inability to find the calibration window, or a blown SCSI terminator fuse.
Refer to Section 5 in this Repair Manual for self-test errors.

Slide Scanner Repair Manual Scanner Overview
Calibration
For SS35/SS35 ES slide scanners, the first calibration is performed at the first requested scan.
It is also performed when the slide scanner detects a specified amount of drift in the lamp or
front end during subsequent scans. The SS35 PLUS performs a full calibration before each
scan.
Refer to Figure 1-8 for a simplified flow diagram of the SS35/SS35 ES slide scanner calibration
routine and to Figure 1-9 for a simplified flow diagram of the SS35 PLUS slide scanner
calibration routine.
Upon completion (passed calibration), the Ready LED indicator lights steady to indicate that the
slide scanner is ready to operate.
Note: The Ready LED indicator continually blinks while the slide scanner cycles through its
calibration.
The following types of adjustments occur during the first calibration:
• Base line integration time to ensure a minimum signal and mitigation of saturation
• Analog gain and offset for base line neutral settings
• Digital uniformity offset calibration
• Digital uniformity gain calibration
• Bad pixel identification
Subsequent scans may require additional analog gain and offset and/or integration time
adjustments to accommodate white points requested by the host or film tables, as a function of
the specific calibration algorithms.
A drift check is also performed with each scan to verify the stability of the front end. Each
calibration that requires a significant change in the front end settings necessitates a
recalculation of the digital uniformity offset correction during the actual scan.
Causes of calibration failure are usually due to a defective lamp, obstructions in the optical path,
a defective sensor (CCD) PC board, a defective main controller PC board, a defective filter, or
a misaligned filter wheel (Original SS35 only).
Refer to Section 5 in this Repair Manual for a detailed list and definition of all calibration type
errors.
