manually cleaning print cartridges

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.
preparing to clean
Remove the print cartridges from the printer before cleaning.
Press the 
 button to turn on the printer; raise the top cover.
The print cartridges move to the center of the printer.
Disconnect the power cord from the back of the printer.
Remove the print cartridges and place them on a piece of paper with the 
ink nozzle plate facing up. 
See the illustration in "Cleaning the Print Cartridges and Print Cartridge 
Cradle" for the location of the ink nozzle plate.
Do not leave the cartridges outside the printer for more than 30 minutes.
 Do not touch the print cartridge ink nozzles or copper 
contacts. Do not remove the copper strips.
