How to Clean Print Heads on an HP F4140 Printer
The HP F4140 is an inkjet printer, meaning it has ink cartridges, which store liquid ink. This ink is squired onto the page by tiny print nozzles located on the bottom of the ink cartridges. Hewlett-Packard made the print head, or the area where the ink passes from the ink cartridge to the paper, a part of the ink cartridges on the F4140. When cleaning the print heads on the printer's ink cartridges, it is important to not touch the tiny nozzles located on the dark square portion on the bottom of the ink cartridges, called the nozzle plate.
