Step 1 :
Turn off the power switch and open the Control Box.
(The power cable may remain connected.)
Step 2 :
With Power Board connector J001 disconnected, turn on the Power Switch and check that
+5 V ± 0.5 V is being output between pins 2 and 1 of J001.
If not, take the following steps to identify the cause:
•
Go to (How to Check the Power Supply Voltages/100 V AC or 200 V AC)
•
If the 100 V AC or 200 V AC check is normal and there is no +5 V output, replace the Power
Board.
Step 3 :
Turn off the power supply momentarily to restore the J001 connector to the Power Board. Turn
on the Power Switch and check that +5 V ±0.5 V is being output between pins 2 (GND) and 1 (+5
V) of J101 on the Main Board. If not, take the following steps to identify the cause:
•
Turn off the power supply momentarily to disconnect J110 (PANEL) from the Main Board and
check again.

from the Main Board and check again.
If this is successful, the Paper Sensor Front Assembly is faulty.
•
Turn off the power supply momentarily to disconnect J107 (Paper Sensor Rear Assembly)
from the Main Board and check again.
If this is successful, the Paper Sensor Rear Assembly is faulty.
•
Turn off the power supply momentarily to disconnect J104 (Lever Sensor Assembly) from the
Main Board and check again.
If this is successful, the Lever Sensor Assembly is faulty.
•
Turn off the power supply momentarily to disconnect J121 (X Encoder) from the Main Board
and check again.
If this is successful, the X Motor is faulty.
Step 4 :
If there is still no +5 V output with all the above connectors disconnected,
•
Replace the DC Cable Assembly
