Description
Power supply (24 V) error
The 24 V port is turned off at the time of job completion
at DADF.
Because the DC Controller turns OFF the 24 V Power
Supply when an error is detected, it is needed to restart
and check the power output before the machine detects
the error to determine whether the cause of the error is
power supply.
If there is no power output, power supply is the cause. If
there is power output, factor other than power supply can
be the cause of the error.
1. Turn OFF and then ON the power.
2. Check the connection between Reader and Printer,
and check that the Cable is not open-circuit.
3. Check the 24 V port of the Reader Controller PCB and
DADF Driver PCB.
4. Check the power supply and Relay PCB on the Printer
side.
5. Replace the Reader Controller PCB and DADF Driver
PCB.
