Clean the electrical connections on a printhead It is possible that the printer will not recognize a printhead after it has been installed. This can happen when ink builds up on the electrical connections between the printhead and the printhead carriage. Under these circumstances, HP recommends that you clean the electrical connections on the printhead. However, routine cleaning of the connections when no problems are apparent is not recommended. A carriage interconnect wiper is included with your printer in the User Maintenance Kit. Use this to clean the electrical interconnects on both the printhead carriage and the printhead if the Reseat or Replace message persists next to the printhead on the front-panel display. 1. Remove a new pre-moistened replacement sponge from its pouch. A supply of sponges is included in the box with the wiper. If all sponges have been used, more can be obtained by calling your service representative. 2. Open the carriage interconnect wiper. Maintain hardware 12 Chapter 4 Hardware maintenance ENWW
