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.
Service Preparation
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.
Important
• Use qualified personnel to service the PROCESSOR.
• Many of the procedures in this manual require that you do the tasks listed below before you do the first step of
the procedure.
– de-energize the PROCESSOR
– drain the TANKS
– remove the CROSSOVERS and RACKS
– remove the ACCESS PANELS
For your convenience, the next several pages contain:
• procedures for completing these basic tasks
• illustrations identifying the major components of the PROCESSOR
