manually cleaning print cartridges
If the printer is used in a dusty environment, a small amount of debris may
accumulate inside the case. This 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.
