3.2 Static Electricity Precautions
The electrostatic charge accumulated in clothing can damage electric elements and
their characteristics. In order to prevent static electricity, touch a metallic part that is
grounded to release the static electricity before disassembling the printer for servicing.
Before discharging static electricity, do not touch electrical sections such as the logic
board and contact points of the carriage ribbon cable (see
Figure 1-6
) when the carriage
ribbon cable is connected to the logic board.
