6. Clean the printhead.
There are three areas of the printhead that need to be cleaned: the plastic ramps
on both sides of the ink nozzles, the edge between the nozzles and the electrical
contacts, and the electrical contacts.
1 Plastic ramps on the sides of the nozzles
2 Edge between nozzles and contacts
3 Electrical contacts
CAUTION: Touch the nozzle and the electrical contact areas only with
cleaning materials and not with your finger.
To clean the printhead
a. Lightly dampen a clean, lint-free cloth and wipe the electrical contact area from
the bottom to the top. Do not go past the edge between the nozzles and the
electrical contacts. Clean until no new ink shows on the cloth.
b. Use a fresh, lightly dampened, lint-free cloth to wipe any accumulated ink and
debris from the edge between the nozzles and the contacts.
