To clean the print cartridge contacts

1. Gather the following items to clean the contacts:

• Distilled water (tap water may contain contaminants that can damage the print

cartridge)

• Cotton swabs or other soft, lint-free material that will not stick to the print cartridge

2. Open the print cartridge door.

3. Remove the print cartridge and place it on a piece of paper with the ink nozzle plate

facing up. Be careful not to touch the copper-colored contacts or the ink nozzle plate

with your fingers.

CAUTION: Do not leave the print cartridge outside the printer for more than 30

minutes. Ink nozzles exposed to the air longer than this may dry out and cause

printing problems.

4. Lightly moisten a cotton swab with distilled water and squeeze any excess water from

the swab.

5. Gently wipe the copper-colored contacts with the cotton swab.

CAUTION: Do not touch the ink nozzle plate. Touching the ink nozzle plate will

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

2 Ink nozzle plate

6. Repeat steps 4 and 5 until no ink residue or dust appears on a clean swab.

7. Insert the print cartridge in the printer, and then close the print cartridge door.

Align the print cartridge

The first time you insert a HP 110 Tri-color Inkjet print cartridge, the printer aligns it

automatically. However, if colors in printouts are misaligned, or if the alignment page does

not print correctly when you insert a new print cartridge, you can use the following

procedures to align the print cartridge again.

NOTE: If you have installed the HP Photosmart software, HP recommends aligning

the print cartridge from the software because it is easier. See the electronic Help for

instructions.
