Handling The Pwb
Observe the following precautions when handling a PWB with ICs.
(1) During Transportation/Storage
1. During transport and storage, PWBs should be kept in conductive bags or on mats and not taken out unless abso-
lutely necessary.
2. PWBs should be stored in a place where direct sunlight does not strike them.
3. Do not touch IC terminals with your hands.
(2) At Replacement
1. Before removing connectors from a PWB, make sure the printer has been unplugged.
2. When PWBs are taken out of their conductive bags or off their mats, hold them by their edges to avoid touching the
terminals or the patterned surfaces.
3. Before installing connectors on a PWB, make sure the printer has been unplugged.
(3) At Inspection
1. Avoid checking a PWB with testers; instead, use operating parts of the printer, indicator lamps, and other means to
evaluate operational conditions.
2. Be careful not to short-circuit IC terminals when using metal tools or screws.
3. If it is necessary to touch elements on the PWB with your hand, make sure your body is properly grounded.
