6. Follow standard electrostatic discharge (ESD) precautions while working on the internal
components.
Static is always a concern when servicing electronic devices. It is highly unlikely that
the area around the copier and the iR-M2 is static-free. Carpeting, leather-soled shoes,
synthetic clothing fibers, silks, and plastics may generate a static charge of more than
10,000 volts. Static discharge is capable of destroying the circuits etched in silicon mi-
crochips, or dramatically shortening their life span. By observing standard precautions,
you may avoid extra service calls and save the cost of a new board.
When possible, work on a ground-connected antistatic mat. Wear an antistatic grounding
strap, grounded at the same place as the antistatic mat. If that is not possible:
• Attach a grounding strap to your wrist. Attach the other end to a good ground.
• When you unpack the iR-M2 from the carton for the first time, touch a metal area of
the copier to discharge the static on your body.
• Before you remove the access panel and handle internal components, touch a metal
part of the iR-M2.
• Leave new electronic components inside their antistatic bags until you are ready to
install them. When you remove components from an antistatic bag, place them on a
grounded antistatic surface, component-side up.
• When you remove an electronic component, place it into an antistatic bag immedi-
ately. Do not walk across a carpet or vinyl floor while carrying an unprotected board.
7. Handle printed circuit boards by their opposing edges only, and avoid touching the con-
tacts on the edge of the board.
8. Never set any liquid on or near the iR-M2 or the copier.
