2. Cover your finger with the cloth and insert it into the printhead slot at the back.
CAUTION: If the carriage remains in the central part of the printer for more than 7 minutes, it
attempts to return to its home position to the right.
3. Rub the cloth against the electrical contacts with a light force along the entire depth of the flex
connector. Try to avoid picking up any ink deposit that may have accumulated on the bottom
surface of the slot.
4. Take special care to clean all contacts thoroughly, including the ones at the lowest point of the
connector.
5. Using the same cloth, clean the strip of electrical contacts on the printhead (unless the printhead is
new). Avoid touching the printhead nozzles.
CAUTION: Do not touch the surface of the printhead that contains the nozzles, because the
nozzles are easily damaged.
