Section 1: Service Overview
Special Tools
Electrostatic Discharge
Overview ESD--electrostatic discharge--is a primary source of:
• product downtime
• lost productivity
• costly repairs
While one cannot feel a static charge of less than 3,500 volts, as few as 30 volts can damage or destroy
essential components in electronic equipment.
Preventive Measures
• Always look for an ESD warning label before doing any procedure involving static-sensitive
components such as CIRCUIT BOARDS. All static-sensitive components are marked with bright
graphic labels, which frequently include instructions. Follow all label instructions.
• Wear a grounding strap when handling static-sensitive components. Always make certain that the
clip remains attached to a properly grounded, unpainted, clean surface.
• Repair static-sensitive components at an ESD-protected work station or use a portable grounding
mat. For help in setting up an ESD-protected work station, contact your Kodak representative.
• When moving static-sensitive components from one area to another, insert and transport the
components in ESD-protective packaging.

De-energizing and Energizing the PROCESSOR
Warning
Dangerous Voltage. Before you replace electrical
components, move the main wall CIRCUIT
BREAKER to “OFF”. Lock the wall CIRCUIT
BREAKER and attach a MAGNETIC POWER
WARNING SIGN TL-1926 to warn others not to
energize the PROCESSOR while you are performing
service.
For most of the service procedures, the PROCESSOR
must be de-energized. To de-energize the
PROCESSOR, move the CIRCUIT BREAKER CB2
on the bottom left corner on the back of the
MULTILOADERtothe “O” position andthemain wall
CIRCUIT BREAKER to “OFF”.
To energize the PROCESSOR, move the main wall
CIRCUIT BREAKER to “ON” and the CIRCUIT
BREAKER CB2 to the “|” position.

Caution
When you remove or install the RACKS, use the
techniques listed below:
• Do not allow the fixer solution to contaminate the
developer solution.
• Install the SPLASH GUARD between the
DEVELOPERTANK andthe FIXER TANK when
you remove the DEVELOPER RACK.
• Use DRIP TRAYS under the DEVELOPER and
FIXER RACKS.
• When you remove the RACKS, lift them out of the
PROCESSOR slowly and tilt them so that the
processing solution drains into the Tank
• When you install the RACKS, insert them in the
TANK slowly to prevent the processing solutions
from splashing over the TANK.
Draining and Filling the TANKS
[1] To drain the TANKS, de-energize the
PROCESSOR and open the DEVELOPER and
FIXER DRAIN VALVES.
[2] To fill the TANKS, do the steps below.
(a) Close the DRAIN VALVES and push the
PROCESSOR into the MULTILOADER.
(b) Energize the PROCESSOR.
(c) From the main menu on the DISPLAY
PANEL, select PROC. Then press:
•GO TO SETUP key
• 4-digit access code, 4213
•OPTIONS key
•REPLEN MODE key
•TANK FILL key
Note
See the Operator Guide, Publication Part No. 240990,
for more details on draining and filling the processing
TANKS.

Adjusting the Squareness of the RACKS
[1] Place the RACK on a smooth, flat surface.
[2] Check whether the SIDEPLATES of the RACK
touch the flat surface evenly. If they do not touch
evenly, apply pressure to the assembly.
See the figure at the left for where to apply
pressure to the DEVELOPER and FIXER
RACKS. See the figure below for where to apply
pressure to the WASH RACK.

[6] Remove the DRIVE SHAFT by slowly pulling it
toward the DRYER END of the PROCESSOR.
[7] If necessary, remove any WORM GEARS that
have wear from the DRIVE SHAFT. Use a
PUNCH to remove the ROLL PIN from the
WORM GEAR.
Important
• Check the direction of the WORM GEARS. See
the figure below for correct installation on the
DRIVE SHAFT.
• When you install the DRIVE SHAFT, install a
quantity of DRIVE SHAFT WASHERS until the
DRIVE SHAFT has minimum play from side to
side.
[8] Reverse the above procedure to install a new
DRIVE SHAFT. Install the same quantity of
