Cleaning Electrical Contacts The printer prints by firing tiny drops of ink onto the media. This is controlled by electrical signals that are sent from the printhead carriage to the printhead through electrical contacts. During normal printing operations, it is possible for ink to get spilt onto these electrical contacts. Ink can also be spilt onto them when printheads are loaded into the carriage. To clean the electrical contacts, you will need some cotton swabs, lint-free cloths, soft tissues or napkins. You will also need some clean water, preferably distilled. Avoid using dry cotton swabs, as lint from the cotton may leave debris or other contaminants; avoid also using dry cloths, as they may scratch delicate surfaces. Alternatively, you can use a suitable cleaning kit, for example, the HP C6247 Ink Cleaner-follow the supplied instructions. 1 Prepare a clean cotton swab by dampening it with distilled water. Rotate the end of the swab between your fingers to pack the cotton and to remove excess water. If you are using a cloth or tissue, make it slightly damp, but not so wet that it drips or disintegrates. If you need to clean more than one ink system, use fresh swabs for each one, to avoid cross-contamination. 76

Cleaning Electrical Contacts
The printer prints by firing tiny drops of ink onto the media. This is controlled
by electrical signals that are sent from the printhead carriage to the printhead
through electrical contacts. During normal printing operations, it is possible for
ink to get spilt onto these electrical contacts. Ink can also be spilt onto them
when printheads are loaded into the carriage.
To clean the electrical contacts, you will need some cotton swabs, lint-free
cloths, soft tissues or napkins. You will also need some clean water, preferably
distilled. Avoid using dry cotton swabs, as lint from the cotton may leave debris
or other contaminants; avoid also using dry cloths, as they may scratch delicate
surfaces.
Alternatively, you can use a suitable cleaning kit, for example, the HP C6247
Ink Cleaner—follow the supplied instructions.

Prepare a clean cotton swab by dampening it with distilled water. Rotate the
end of the swab between your fingers to pack the cotton and to remove
excess water.
If you are using a cloth or tissue, make it slightly damp, but not so wet that it
drips or disintegrates.
If you need to clean more than one ink system, use fresh swabs for each one, to
avoid cross-contamination.
