Cleaning the corona wire
When your prints show vertical light streaks that are wavy and appear in all colors, the corona wire needs to be cleaned. If cleaning doesn't take care of the problem, the corona wire may be worn out and need to be replaced. Separate replacement of the corona wire should not be required often, since each new imaging unit includes a new corona wire already installed, and the average life of these two components is similar.

  1. Turn the power off.

  2. Open the front door.

  3. Pinch the handle of the corona wire to remove it.

  4. Remove the cleaning tool from inside the printer.

  5. Insert the cleaning tool on the underside of the corona wire housing, as shown.

  6. Wipe the corona wire with a back and forth motion.

  7. Replace the cleaning tool inside the printer.

  8. Replace the corona wire in the printer.

  9. Close the front door and turn the power on.
