See Replace a printhead on page 30. 6. Insert the carriage interconnect wiper into the printhead slot at the back. Wipe the electrical contacts by inserting the tool between the electrical connections at the back of the slot and the steel spring, with the sponge facing away from you and towards the electrical contacts.

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. 7. Rub the sponge against the contacts with a light force along the entire depth of the flex connector, inserting the wiper as far as allowed by the mechanical stop on the tool.
