How do I clean the corona wire of the drum unit?
If you are experiencing print quality problems, please clean the corona wire as follows:
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.

Unplug the printer.

- Carefully turn the drum unit upside down.
-
Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.
-
Return the tab to Home position before reinstalling the drum unit.
Be sure to return the tab to the Home position, or printed pages may have vertical stripes.
- Re-install the drum unit into the printer.
