Flowchart B

YES

No power is getting into the printer.

NO

Did the

problem first appear

following take apart and

reassembly of the

printer?

Make sure that the line voltage is present

and that the printer is plugged in.

Is the circuit breaker thrown? (You can

tell by looking through a small cutout

in the power supply, right above the

power plug). If it is thrown, reset it and

switch on the printer again. If the circuit

breaker is thrown again, check to see

whether the AC power is shorted.

If the problem persists, replace the

power supply.

Check the following connectors and make

sure they are securely attached.

• The connector on each side of the transit

coupling behind the power supply.

• Connector J4 and J6 at the power supply.

• Connector J101 at the DC controller

board (this is the connector that carries

the power-on/power-off signals).
