Manually clean print cartridges
If the HP Deskjet is used in a dusty environment, a small amount of debris can
accumulate on the print cartridge contacts. This debris can cause ink streaks and missing
lines on printed pages. The problem can be corrected by manually cleaning the print
cartridge contacts.
You need the following items to clean the print cartridges:
●
Distilled water (tap water can contain contaminants that can damage the print
cartridge)
●
Cotton swabs or other soft, lint-free material that will not stick to the print cartridge
Be careful not to get
ink on your hands or clothing
as you clean.

2.
Wait until the print cartridge cradle moves to the right side of the HP Deskjet and is
idle and quiet.

To manually clean print cartridge contacts
1.
Lightly moisten a cotton swab with distilled water and squeeze any excess water
from the swab.
2.
Gently wipe the print cartridge copper contacts with the cotton swab.

nozzles will result in clogs, ink failure, and bad electrical connections.
