Using and Caring for Your Print Cartridges 3
If You See Ink Streaks...
Clean the print cartridges and the print cartridge cradle by
following the instructions below.
1 Double-click the HP DeskJet 640 Series Utility icon in the
Utilities folder on your hard drive’s main directory.
2 Click the Clean panel, then click the Clean button. If this does not prevent
streaks, follow the instructions for “Manually Cleaning the Print Cartridges”
below.
Be careful not to get ink on your hands or clothing.
Manually Cleaning the Print Cartridges and Print Cartridge Cradle
In order to properly clean the print cartridges and cradle, you will need distilled or
bottled water and cotton swabs or a similar lint-free absorbent material that will
not stick to the cartridges.
Manually Cleaning the Print Cartridges
1 Press the Power Button to turn the printer on, then lift the top cover.
2 After the print cartridges move to the center and stop, unplug the power cord
from the back of the printer.
Keep new and used print cartridges out of the reach of children.
3 Remove the print cartridges and place them wide side down on a piece of
paper.
Do NOT touch the print cartridge ink nozzles or copper contacts. Touching
these parts will result in clogs, ink failure, and bad electrical connection.
Also, do NOT remove the copper strips; these are required electrical
contacts.
4 Dip a clean cotton swab into distilled water and squeeze any excess water from
the swab.
