Clean the corona wire
Please follow the steps below to clean the corona wire.
DO NOT use flammable substances or any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

Take out the drum unit and toner cartridge assembly.
- We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
- Handle the drum unit and toner cartridge assembly carefully. If toner scatters on your hands or clothes, immediately wipe or wash it off with cold water.
- To prevent damage to the machine from static electricity, DO NOT touch the electrodes shown in the illustration.
Clean the corona wire inside the drum unit by gently sliding the green tab from left to right and right to left several times.
Be sure to return the tab to the home position (1). If you do not, printed pages may have a vertical stripe.
Put the drum unit and toner cartridge assembly back into the machine.
Close the front cover of the machine.
