Description: Ghost occurs at 75.5 mm intervals of the OPC drum in the whole printing.
Causes: 1. Bad contacts caused by contamination from toner particles between high voltage terminal in the main body and the electrode of the Developer. 2. Bad contacts caused by contamination from toner particles between high voltage terminal in the main body and the one in the HVPS board. 3. The life of developer is expired. 4. Transfer roller lifetime(60,000 sheets) has expired. 5. Abnormal low temperature(below 10°C). 6. Damaged cleaning blade in the developer.
Remedy: 1. Clean the contaminated terminals. 2. Problem in the toner cartridge, replace the toner cartridge and try to print out. 3.
