SOURCE: I do not know how to change my printhead on my HP Officejet Pro L7580
---Make sure the printer is on, or press the Power button to turn it on. Wait for the printer to finish any warm-up diagnostics or print jobs it is performing.
---Open the access cover to the print heads. This cover may be the top cover, the front door or an ink access door on the front of the printer.
---Wait for the cartridge carriage to stop moving, making sure it is completely stationary before putting your hand in the printer. Lift up any clips or latches keeping the print heads or cartridges in place.
---Remove the old print head or ink cartridge if it is part of the cartridge, and discard it. Remove the packaging from the new print head, making sure to peel off any protective tape or twist-off protective caps.
---Insert the new print head or cartridge into the empty slot. Lower any clips or latches and make sure the print head or cartridge does not wiggle in its spot, otherwise you need to pull it out and reinsert it into the printer.
---Close the cover you opened to access the print heads and wait for the printer to calibrate the new print heads. Some printers may produce an alignment page, which you can throw away.
