Inkjet Cartridges
By Richard Romando

A contraption that contains or encases the ink, an inkjet cartridge comes in different combinations. With the proliferation of models of inkjet printers from various manufacturers, inkjet cartridges also come as separate black and color cartridges, black and color ink in one cartridge, and ink tanks for every ink color. An ink tank of several inkjet printers houses the control circuitry, which decodes the information transmitted from the computer to the printer, and the print head, wherein the nozzles are located.

Only a handful of companies supply printers with a built-in print head. The print head of some inkjet printer models are already incorporated and fixed inside the printer itself. The good thing about this is that a user need not replace the print head every time the ink runs out. On the other hand, the entire printer should be replaced or repaired once the print head itself is damaged.

By and large, a print head is connected to detachable and replaceable ink tanks. Most models of up-to-date inkjet printers are designed with this kind of setting. Unlike in a printer with a fixed print head design-wherein the entire printer has to be replaced if broken-this inkjet technology is not as costly since a user can just purchase a new cartridge if the print head breaks down. However, when the inkjet cartridge frays or runs out of ink, the whole cartridge should be replaced. A brand-name inkjet cartridge costs more than a laser cartridge, which makes inkjet printers costly and difficult to maintain and operate. However, cost-conscious consumers today have opted for compatible standard inkjet cartridges or make use of refill kits. These cheaper alternative ink tanks and refill sets or remanufacturing services appeal to economical computer-users but not to selected printer makers.

InkJet Cartridges
By Simon Rogers

An inkjet cartridge is a replaceable component of an inkjet printer that contains the ink that is spread on paper during printing and sometimes the print-head itself. Each inkjet cartridge contains one or more partitioned ink tanks (reservoirs), electronic contacts and a chip that communicates with the printer.

Inside each partition of the inkjet cartridge tank (reservoir), is a tiny metal plate. In response to a signal given by the inkjet printer, a tiny current flows through the metal causing it to warm up. The ink immediately surrounding the heated plate is vaporised. As a consequence, the total volume of the ink exceeds that of the inkjet cartridge. An ink droplet falls out of the cartridge onto the paper. This process takes place in a matter of milliseconds which equals to near 6,000 times per second.

Usually, two separate inkjet cartridges are inserted into an inkjet printer: one containing black ink and one with each of the three primary colors (cyan, magenta and yellow). Alternatively, each primary color may have a dedicated inkjet cartridge. Some inkjet cartridges are specifically designed for printing photographs. All printer suppliers produce their own type of inkjet cartridges. Inkjet cartridges for different printers may be incompatible – either physically or electrically. Since replacement inkjet cartridges from the original manufacturer of the printer are often very expensive, some other manufacturers produce “compatible” inkjet cartridges as cheaper alternatives. Some inkjet cartridges have incorporated the printer head (most Hewlett Packard inkjet printers use this system). Usually, they are more expensive, but the printers are cheaper. Others don t include the print head, but they are more economical and the inkjet printers are more expensive (for example, most Epson inkjet printers).

Typically, inkjet cartridges are very expensive compared to the printer itself. Many people, therefore, use compatible inkjet cartridges (also called “generic” – those made by a company other than the OEM printer manufacturer) that give comparable quality, but with considerable savings. Another alternative involves modifications that allow the use of continuous ink systems that use external ink tanks. Some people choose to use inexpensive ink, knowing that, in the long term, it may damage the printer. However, the cost savings of 4 or 5 refilled inkjet cartridges may well be sufficient to pay for a new inkjet printer. If the printer lasts more than that, they have obtained the same result (economically speaking) at a lower cost than using original supplies.

Consumers are often surprised at the price of replacing their inkjet cartridges, especially when compared with that of purchasing a brand new inkjet printer. The major printer manufacturers, Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother, often break even or lose money selling printers and expect to recoup their losses by selling inkjet cartridges over the life span of the printer. Since much of the printer manufacturers profits are made up of inkjet cartridges and toner sales, these companies have taken various actions to limit the options of consumers in using aftermarket inkjet cartridges.

However, many consumers have purchased remanufactured cartridges from alternative companies to save money over buying new inkjet cartridges. This is a much better use of resources, much cheaper, and a whole industry has grown up around this idea. Remanufacturing of inkjet cartridges and other printer supplies also reduces the amount of plastic that goes in the landfill and keeps the Earth a cleaner place.
