Procedure 2: Eliminating ink streaks
Customers using HP DeskJet printers in dusty
environments might occasionally experience ink
streaks or smearing because of a small
accumulation of debris inside the printer. This debris can
include dust, hair, carpet, or clothing fibers. Ink streaking is
easily prevented or corrected by doing scheduled cleaning to
two areas of the printer: the print cartridges, and the print
cartridge cradle.
Materials you will need
Before you begin, make sure you have the following materials
available:
• Cotton swabs or any soft material that will not come apart or
leave fibers (for example, a piece of clean cotton cloth).
• Distilled, filtered, or bottled water (tap water might contain
contaminants that can damage the print cartridges).
• Scrap paper or paper towel on which to set the print
cartridges while you are working.
Be careful not to get ink on your hands
or clothing.
