IV. MALFUNCTION TROUBLESHOOTING
E-1 No power
< possible causes >
1. The POWER ON signal is not input because of the poor contact in the interface connector.
Action:
Reconnect the interface connector correctly.
2. Blown fuse
Action:
Remove the power supply unit and replace the fuse.
3. Over-current/over-voltage detection circuit triggers
Action:
Disconnect the power connector and reconnect it. If the problem persists, investi-
gate the factor that activates the over-current/over-voltage detection circuit. Turn
the power switch ON at least two minutes after the power switch is turned OFF.
4. Power supply failure
Action:
Turn the printer power switch OFF, and disconnect the connector J901 from the
power supply unit.
Turn the power switch ON, and measure the output of the DC power supply of the
connector J901.
Be sure not to short the connector.
Replace the power supply unit if the specified value is not output.
5. Wiring, DC load, and paper deck driver PCB
Action:
Turn the power switch OFF, and check the wires and DC loads connected between
the paper deck driver PCB and other units. Replace the paper deck driver PCB if
the wires and DC loads have no problem.
E-2 Feed motor failure
< possible causes >
1. Poor contact in the FEED MOTOR DRIVE signal line connector.
Action:
Reconnect the feed motor connector J315 and the connector J207 on the paper
deck driver PCB correctly.
2. Feed motor failure
Action:
Replace it.
3. Paper deck driver PCB failure
Action:
Replace it.
