Waste Motor Error
This error is caused by open circuit of Waste Motor Harness or the
motor stalling due to increased Waste Motor torque during operation.
1. Open the Front Cover and then check if the Waste Toner Tank is full or the waste inlets are blocked with the Waste Toner.
--> Replace the Waste Toner Tank and unblock waste inlet feeds.
2. Open the Top Cover and then remove the ITB Unit and OPC Unit and check if the OPC waste toner outlet blocked.
3. Remove the Front Cover and then check the Waste Motor Harness.
--> Refit or replace the harness if it is damaged.
4. Remove the HVPS Cover and then check that the HVPS OEM Harness is correctly fitted.
--> Refit or replace the harness if it is damaged.
5. Measure the Voltage on CN2 Pin1 and Pin3 of OEM PBA. (Normal : Over +10VDC)

Image Transfer Error
This is caused by a badly fitted or unlocked ITB unit or a faulty ITB
Home Sensor.

--> Remove, replace and re-lock the ITB unit.
--> If the same fault recurs regularly replace the ITB unit.
2. Check the condition of the ITB Harness (especially if replacing the ITB does not resolve the problem).

3. Check the signal on Pin 1 of CN10 on the Main PBA.

Invalid Drum Cartridge
Can not communicate with the OPC Unit.

--> If not replace the OPC drum.
2. Clean the OPC unit contact points.
3. Check the Harness connected between the Main PBA and Toner OPC Unit.
