V. MALFUNCTION TROUBLESHOOTING

If the factor of malfunction was identified as "malfunction troubleshooting" by the malfunction
diagnosis flowchart (Figure 4-1-1), perform the following actions.

V-1. No power

<Possible causes>

1. POWER-ON signal is not input due to poor contact in option interface connector.

Action:

Reconnect the option interface connector correctly.

2. Blown fuse

Action:

Remove the power supply unit and replace the fuse.

3. Power supply unit failure

Action:

Turn OFF the printer power switch. Disconnect the connector J1 from the staple
stacker driver PCB.
Plug the power cord to the power supply unit, and then turn ON the printer power
switch. Then, measure the output of the DC power supply of the connector J1,
making sure not to short it.
If the specified value is not output, replace the power supply unit.

4. Wiring, DC loads, staple stacker driver PCB.

Action:

Turn OFF the printer power switch. Check the wiring and DC loads ahead of the
staple stacker driver PCB. If the wiring and DC loads are normal, replace the sta-
ple stacker driver PCB.
