1151SBS0101A

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 and they 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.

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 a metal part to discharge static electric-
ity before touching the PWB.
