4-4 The cause and solution of the malfunction
4-4-1 All LEDs blinking (Fuser Error)
• Description
1. All the lamps on the operator panel blink.
2. Gear of the fuser does not work and breaks away melt away.
When printing, motor breaks away from its place due to defective fuser gear.
Check and Cause
Solution
1. Check if the thermostat, AC wire and Heat Lamp is
open.
2. Check if the thermistor sensor is in place.
3. Check if the heat lamp works properly.
4. Check if the overheat circuit works properly.
5. The fuser gear is defective due to melting away.
1. If the thermostat is open replace the fuser and
check following items.
2. If the thermistor sensor device is located deep in the
sponge, replace the fuser.
3. Check if the circuit of overheat mode works properly.
4. Run DCU mode : Perform DCU diagnostic code 10.
4-4-2 All LEDs blinking (Scan Error)
• Description
1. All lamps on the operator panel blink.
Check and Cause
Solution
DCU Mode : Perform DCU diagnostic code 05. If the DCU
error code 95 is displayed, replace LSU.
Replace LSU.
(Service Parts : Figure 13, chapter 5)
If you cannot solve the problem after you replace LSU,
replace the main board.
