Electrostatic Discharge Every Day

ESD--electrostatic discharge--is a primary source of:

• product downtime,

• lost productivity,

• costly repairs. While we cannot even feel a static charge of less

than 3,500 volts, as few as 30 volts can damage or destroy essential components in the electronic equipment upon which we rely.

As technology continues to advance, these advanced components will be even more vulnerable to ESD destruction.

The conclusion is clear. To take charge of productivity and profitability, we must reduce ESD.

Effective ESD control requires the following things.

Awareness

Everyone

• ESD is a primary source of frustrating equipment failures and intermittent malfunctions.

• ESD affects productivity

• ESD can be controlled. ESD-protected workstations.)

[1] Do not store trash near static-sensitive

equipment.

[2] Do not place plastic materials near electronic

components. Trash can liners and plastic foam cups generate static electricity that damages or destroys electronic components.

[3] Look for the label. Static-sensitive

components are marked with bright graphic labels. Follow label directions.

[4] Spray the carpet. Walking over a carpet is a

major cause of ESD. In low-humidity environments, periodically spray carpets with an anti-static preparation, available at local stores.

During Maintenance and Repair

[5] Wear a grounding strap when handling

static-sensitive components. Always make certain that the clip is attached to a correctly grounded, unpainted surface.

[6] Use a portable grounding mat if you cannot

repair components at an ESD-protected workstation. (Kodak’s Customer Equipment Services Division can assist you in setting up

Overview of Processor

Many of the following procedures require that the processor be deenergized before the procedure is begun. Many of the procedures also require that the TOP COVER and 6 ACCESS PANELS be removed from the processor before the procedure is begun. For your convenience, illustrations showing the location of the TOP COVER, ACCESS PANELS, MAIN CIRCUIT BREAKER, RACKS, CROSSOVERS, and other major components appear on the following pages.

Adjusting the Side Plates

[1] Remove the DETECTOR CROSSOVER

ASSEMBLY from the processor.

[2] Set the DETECTOR CROSSOVER

ASSEMBLY on a flat surface.

[3] Loosen the SCREWS of the TIE RODS. [4] Check the SIDE PLATES for squareness

against the flat surface.

[5] Tighten the SCREWS.

NOTE

The GUIDE SHOES are not adjustable.

[6] Check that the longer TIPS of the GUIDE

SHOES are in the direction of the film travel.

[7] Do this procedure for each CROSSOVER

ASSEMBLY.

Adjusting the Chain

[1] Check that the CHAIN is wet with solution. [2] Check that the RACK ASSEMBLY is almost

the same temperature as the solutions in the tanks.

[3] Loosen the 4 HOLDING SCREWS. [4] Hold the RACK ASSEMBLY above the work

surface. This will allow the TURNAROUND to move by gravity to provide the correct tension on the CHAIN.

[5] Tighten the 2 HOLDING SCREWS on the

drive side.

[6] Rotate the DRIVE GEAR one full rotation. [7] Set the RACK ASSEMBLY down on the work

surface.

[8] Using the ADJUSTING SCREWS, make the

distance between the RACK SIDE PLATE and the TURNAROUND SIDE PLATE on the non-drive side equal to the drive side.

[9] Tighten the 2 HOLDING SCREWS on the

non-drive side.

Installing the Chain

[1] To open the CHAIN, insert a SCREWDRIVER

under the open end of each LINK. Rotate the SCREWDRIVER.

[2] Install the CROSSBAR of each LINK in the

direction of travel, with the LINKS opening outward. See figure 2-4.

[3] Attach the new CHAIN to the existing CHAIN. [4] Pull the existing CHAIN through the RACK

until the new CHAIN is in the correct position.

IMPORTANT

When closing the open LINK of the new CHAIN, do not change the pitch of the curved side of the LINK.

[5] Disconnect the existing CHAIN from the new

CHAIN. Fasten the ends of the new CHAIN together.

NOTE

Do not make the MOTOR DRIVE CHAIN too tight.

Lubricating the Chain

Do not allow the DRIVE CHAIN to operate without lubrication.

[7] Check that the MOTOR DRIVE CHAIN is lubricated.

Figure 4-5 Aligning the Blower Drive Belt

Correct tension is obtained if the BLOWER DRIVE BELT does not make loud noises when you energize the processor. This step requires that you energize the processor in order to test for correct tension, and then deenergize the processor to correct the tension.

[10] When the correct tension of the BLOWER DRIVE BELT is obtained, tighten the 3 MOTOR MOUNTING

BOLTS.
