Electrostatic discharge (ESD) procedures
Read the following electrostatic discharge (ESD) information because, if discharged into the circuitry of an
integrated circuit, static electricity can damage the circuit. The following Attention notice in the text of this book
warns of possible damage caused by ESD.
Attention:
This is an ESD sensitive area. See "Electrostatic discharge (ESD) procedures" before working with
parts that are sensitive to ESD.
Follow these guidelines to prevent damage to ESD-sensitive components:
v Keep an ESD-sensitive part in its original shipping container, usually a protective bag, until you are ready to
install it.
v Make the fewest possible movements to minimize static electricity.
v Touch the metal frame of the printer or the assembly to discharge static electricity in your body just before
touching the ESD-sensitive part.
v Hold the ESD-sensitive part by its edges. Do not touch any components, pins, or connectors. If possible, keep
one hand on the frame while you are installing or removing an ESD-sensitive part.
v Do not place an ESD-sensitive part on anything that can provide a discharge path from your body through the
ESD-sensitive part. If you need to put down the ESD-sensitive part, first put it into the ESD protective wrapper
in which it was shipped.
v Prevent ESD-sensitive parts from being touched by other persons.
v Cables may connect to engine cards or boards that are ESD-sensitive. Be careful when working with
connectors.
v Be careful when working with ESD-sensitive parts when the humidity is low. Low humidity increases static
electricity.
Using the ESD kit
To safely discharge all static electricity, use the ESD kit following the guidelines under "Electrostatic discharge
(ESD) procedures."
v Turn off the printer before you put on the ESD wrist band.
v Connect the wrist band to an unpainted, frame-ground point of the printer.
