PC boards are sensitive to static electricity. If a person handles a PC board while charged with static
electricity, the parts on the PC board may be damaged. Before handling a PC board, discharge the
static electricity from your body; for example, by touching the surface of grounded metal.
Turn off the power switch of the machine. (See “8A-8-1 Turning the Power Switch On” on page 95.)
Remove the service panel U from the front assembly. (See step
