•
Before transporting or storing the PWBs, put them in protective conductive cases or bags
so that they are not subjected to high temperature and are not exposed to direct sunlight.
•
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 (such as a carpet or plastic bag).
•
Do not touch the parts and printed patterns on the PWBs with bare hands.
•
Whenever replacing the PWB, make sure that the power cord of the copier has been
unplugged.
•
When the power is on, the connectors should never 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 to dis-
charge static electricity before touching the PWB.
