Part 1: Safety and Precautions

BJC-7100

3.4 Static Electricity

The electrostatic charge accumulated in clothing can damage electrical components and alter their electrical characteristics.

Before disassembling the printer to service it, use a wriststrap or other grounded metal object to discharge the static electricity. The following parts must not be touched before you have discharged the static electricity from your body:

•Logic board, carriage board

•Motor control board

•Cable connectors and contacts

•BJ cartridge signal contacts

Static Damage!

Carriage Board

Carriage Motor

BJ Cartridge Signal Contacts
