All of the HP printers I have encountered so far have the print head as part of the ink cartridge. Change the cartridge and you automatically change the printhead.

This is the reason why HP cartridges are so much more expensive than Epson, for instance.

Step one: Remove the old cartridges

1. Press the Power button ( ) to turn on the product, if it is not already turned on.
2. Open the cartridge access door. The carriage moves to the center of the product. Wait until the carriage is idle and silent before continuing. Figure 1: Open the cartridge access door
3. To remove an old cartridge, press the tab on the front of the cartridge, and then pull it up to remove it from its slot. Figure 2: Remove the cartridge from its slot
4. Repeat the previous step to remove each of the cartridges.

Step two: Remove the old printhead

1. Lift the latch handle on the carriage until it stops. Figure 3: Lift the latch handle
