(6) Replacing the Air Cannon Speaker
To avoid electric shock, accidents or injuries to yourself or other people, or damage to the
electronic circuits, be sure to turn off the power switch before starting work.
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
of “8B-4-1(5) Replacing the AIR
CAN PC Board” on page 111.)
Disconnect the connector, remove the four flange socket bolts (M4 x 25) while holding the air cannon
speaker in place, and then remove and replace the air cannon speaker.
