Description

Most consumer inkjet printers, such as those made by HP Lexmark canon samsung brother expert Epson printers use a thermal inkjet; inside each partition of the ink reservoir is a heating element with a tiny metal plate or resistor. In response to a signal given by the printer, a tiny current flows through the metal or resistor making it warm, and the ink in contact with the heated resistor is vaporized into a tiny steam bubble inside the nozzle. As a consequence, an ink droplet is forced out of the cartridge nozzle onto the paper. This process takes a fraction of a millisecond.
The printing depends on the smooth flow of ink, which can be hindered if the ink begins to dry at the print head, as can happen when an ink level becomes low. Dried ink can be cleaned from a cartridge print head using isopropyl alcohol or water. Isopropyl alcohol will damage the printing head, IPA can dissolve the plastic at the connections and rubber gaskets. Tap water contains contaminants that may clog the print head, so distilled water or alcohol or foam cleaning and a lint-free cloth is recommended.
The ink also acts as a coolant to protect the metal plate heating elements when the ink supply is depleted, and printing is attempted, the heating elements in thermal cartridges often burn out, permanently damaging the print head. When the ink first begins to run low, the cartridge should be refilled or replaced, to avoid overheating damage to the print head cartridge.
