PRECAUTIONS FOR HANDLING THE PWBs

1-1.

Precautions for Transportation and Storage

• Before transporting or storing the PWBs, put them in protective conductive cases or bags
so that they are not subjected to high temperature (they are not exposed to direct sun-
light.)
• Protect the PWBs from any external force so that they are not bent or damaged.
• Once the PWB has been removed from its conductive case or bag, never place it directly
on an object that is easily charged with static electricity (carpet, plastic bags, etc.).
• Do not touch the parts and printed patterns on the PWBs with bare hands.
1-2.

Precautions for Replacement and Inspection

• Whenever replacing the PWB, make sure that the power cord of the copier has been
unplugged.
• When the power is on, the connectors must not be plugged in or unplugged.
• Use care not to strap the pins of an IC with a metal tool.
• When touching the PWB, wear a wrist strap and connect its cord to a securely grounded
place whenever possible. If you cannot wear a wrist strap, touch the metal part before
touching the PWB to discharge static electricity.
