unit if vertical white lines appear on your printed page.

If vertical white lines appear on your printed page, you need to
clean the developer unit with the developer cleaner. Follow these
steps:

accessory pack that comes with your printer. A cleaner is also
packed with replacement drum units.
2. Raise the top cover of your printer by lifting up on the latch.
