Description: Print density is uneven between left and right.
Causes: 1. The pressure force on the left and right springs of the transfer roller is not even, the springs are damaged, the transfer roller is improperly installed, or the transfer roller bushing or holder is damaged. 2. The life of the Developer has expired. 3. The toner level is not even on the developer roller due to the bad blade.

Display: Background
Description: Light dark background appears in whole area of the printing.
Causes: 1. Recycled recording paper has been used. 2. The life of the Developer has expired. 3. The up-to-down movement of the transfer roller is swift? 4. The HVPS is normal? (Perform DCU diagnostic code 01-04)
Remedy: 1. B/S is not guaranteed when using recycled paper. 2. Replace the Developer that has expired. 3. Clean the busing part of the transfer roller. 4. Replace the Developer if not solved by the above direction 1-3.
Code: 09
Display: Ghost (1)
Description: Ghost occurs at 96 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(125,000 sheets) has expired. 5. Abnormal low temperature(below 10°C). 6. Damaged cleaning blade in the developer.
Remedy: 1. Clean the terminals when contaminated by toner particles. 2. Occur in the developer cartridge, replace the developer and try to print out. 3. Replace the engine board if not solved by the above directions 1-2. 4. If not solved by the direction 3, check the transfer roller lifetime and replace it. 5. Wait about 1 hour after power on before using printer. 6. Occur in the developer cartridge, replace the developer and try to print out.
