Error Blurred image

[Description ]When the picture is out of focus generally or partially

[Parts of Defect]

1. Developing Machine Cartridge(DMC)

2. HVPS

3. Zener PBA’s assembling condition

[Check and Cause]

1. Developing roller is infected due to toner in DMC almost exhausted

2. Loosing contact of high-tension terminal and developing machine electrode in set due to toner, et cetera.

3. Loosing contact between Zener PBA GND and Frame GND.

[Solution]

1. Replace DMC

2. Cleaning the infected parts from toner, etc.

3. If you cannot solve the matters for above solutions, change HVPS.

4. Check the connected condition of Zener PBA, disconnected or shorted state of OPC GND Harness.

Error Settle Machine Error ( Open, Low, Over Heat Error)

[Description ]

1. Display :“#U1-2320” ( Open_Heat Error )

“#U1-2330” ( Low_Heat Error )

“#U1-2340” ( Over_Heat Error )

[Parts of Defect]

1. Fuser

2. Fuser Controller Micom

3. Fuser Harness

[Check and Cause]

1. Check Thermostat is Open.

2. Check Thermistor in position.

3. Check Heat Lamp is working.

4. Check Heat Lamp’s resistance value.

5. Check reappearing same problem using Power on/off.

[Solution]

1. If Thermostat was disconnected, replace Settle Machine.

2. If Thermistor wasn’t in position, replace Settle Machine.

3. If Heat Lamp’s resistance value was incorrect, replace Heat Lamp.

4. If the same problem’s reappeared after several Power on/off, cover on and check open/short of FDB Harness in PBA.

Trouble & Solutions(3)

Error LSU Error (LSU Motor Error)

[Description ]

1. Exceptional signal of nLSU_READY.

2. Display : “#U2-1113”

[Parts of Defect]

1. LSU

2. LSU Harness

3. Main Controller

[Check and Cause]

1. Check th Pmotor is stable.

2. Check the LSU_3.3V power is normally supplied.

3. Check the LSU Harness is normally assembled.

[Solution]

1. Check LSU Harness short/open.

2. Check LSU_3.3V power supply.

3. Replace LSU

4.If the same problem’s reappeared after replacing LSU, change Main controller.

Ⅴ. Repair

Error Cover open

[Description ] 1. Display : “Door open close it”

[Parts of Defect]

1. Front Cover ‘s hook, HVPS Switch , RearCover Switch

2. SMPS

[Check and Cause]

1.Check Hook lever of Front Cover is damaged or transformed.

2. Check HVPS Switch and Rear Cover Switch are transformed.

3. Check the main motor is working when you power on the product.

[Solution]

1. If the Hook lever is trouble, replace it.

2. If HVPS Switch is trouble, replace it.

3. IF Rearcover Switch is trouble, replace Outbin Full Sensor & Rear Cover (All - in - one Switch)

Trouble & Solutions(4)

Ⅴ. Repair

Error Poor power supply

[Description ]When the product isn’t working after insertion power cable and push the power button.

[Parts of Defect]

1. SMPS

2. OPE Harness

3. Engine PBA

[Check and Cause]

1. Check input/output power of SMPS is normal.

2. Check LED lamp isn’t working when the product is normally warming up.

(If LED lamp wasn’t turned on, Check OPE Harness in Main PBA)

[Solution]

1. Replace power cable or SMPS

2. Replace Main Controller

3. Replace Engine Controller

3. Check Harness short/open on Main Controller

Trouble & Solutions(5)

Ⅵ note Q&A

1. Check Power Supply.•Check the power is turned on.•Check the power cable is connected with socket. •Check the voltage of power socket.

2. Check Panel• Is LED lamp working on OPE?-->If LED lamp wasn’t turned on check power cable, SMPS and Main board•Is LED lamp not working unusually?-->Check Main PBA and Harness

3. Check Paper Process(Route)• In case of the JAM?-->Removing paper in route. • Jam is repeated continuously in C route?-->Removing paper to open the rearcover back of settle machine.-->Detailed check the cause of JAM to disassemble the product.

Ⅷ note Q&A

4. Printing Information Page• Printing test page-->If you own the error check cable and printer driver was installed.

5. Check the quality of printing• Trouble with printing quality?-->Refer to the blurred image

6. Check the consumables• Check Test Pattern--> Printing and check expected life of consumables. If it is almost exhausted, replace it.
