manually cleaning print cartridges

If the printer is used in a dusty environment, a small amount of debris may
accumulate inside the case. Debris can include dust, hair, carpet, or clothing
fibers. When it gets on the print cartridges and cradle, it can cause ink
streaks and smudges on printed pages. Ink streaking is easily corrected by
manually cleaning the cartridges and cradle.

gathering cleaning supplies

You will need the following items to clean the print cartridges and cradle:

• Distilled or bottled water. Tap water contains contaminants that

damage print cartridges.

• Cotton swabs or other soft, lint-free material that will not stick to the

cartridges.

Be careful not to get ink on your hands or clothing as you clean.
