An ink cartridge is a replaceable component of an ink-jet printer that contains the ink and sometimes the print-head itself that is spread on paper during printing. Each ink cartridge contains one or more partitioned ink reservoirs, electronic contacts and a chip that communicates with the printer. Inside each partition of the ink reservoir is a tiny metal plate. In response to a signal given by the printer, a tiny current flows through the metal causing it to warm up. The ink immediately surrounding the heated plate is vaporized. As a consequence, the total volume of the ink exceeds that of the cartridge. An ink droplet falls out of the cartridge onto the paper. This process takes place in a matter of milliseconds. Typically, two separate ink cartridges are inserted into a printer. One contains black ink and one with each of the three primary colors. Alternatively, each primary color may have a dedicated cartridge. Some ink cartridges are specifically designed for printing photographs. All printer suppliers produce their own type of ink cartridges. Cartridges for different printers may be incompatible either physically or electrically. Since replacement cartridges from the original manufacturer of the printer are often very expensive, some other manufacturers produce `compatible` ink cartridges as cheaper alternatives. Some ink cartridges have incorporated the printer`s head. Usually, they are more expensive, but the printers are cheaper. Ink cartridges are generally very expensive. An alternative approach is that many people use compatible ink cartridges that provide the same quality, but with savings up to 90% or the other alternatives involve modifications that allow the use of continuous ink systems that use external ink tanks. Another approach is that some people use inexpensive ink, knowing it may damage the printer, but the savings are so important that they may pay for a brand new printer with the savings after 4 or 5 refilled ink cartridges. Consumers are often surprised at the price of replacing their printer ink cartridges, especially when compared with that of purchasing a brand new printer. Since much of the printer manufacturers` profits are made up of ink and toner cartridge sales, these companies have taken various actions to limit the options of consumers in using aftermarket cartridges.
