The HP Officejet Pro L7680 uses a print head to deliver the ink from the ink cartridges onto the paper or other media as it passes through the inside of the printer. The print head contains tiny nozzles that direct the ink droplets to their final destination on the media. Problems with the print heads will cause jagged or broken lines as well as splotchy printouts. Take corrective action for the L7680's print heads from the control panel.
