Creating an ESD safe environment
• Follow standard ESD (electrostatic discharge) precautions while working on the internal
components of the E-8100.
Static is always a concern when servicing electronic devices. It is highly unlikely that the area
around the copier and the E-8100 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 microchips, 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, do the
following:
• Attach a grounding strap to your wrist. Attach the other end to a good ground.
• When you unpack the E-8100 from the carton for the first time, touch a metal area of the
copier to discharge the static on your body.
• Before you remove any of the E-8100 panels and handle internal components, touch a
metal part of the E-8100.
• 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 in an antistatic bag immediately. Do
not walk across a carpet or vinyl floor while carrying an unprotected board.
• Handle printed circuit boards by their opposing edges only and avoid touching the contacts
on the edge of the board.
