Ink cartridges: How do they work ?

By Andrew James

Ink cartridges are replaceable components found in inkjet printers, containing the ink used for printing. Sometimes, the ink cartridges can contain the printer's print head. An ink cartridge contains one or more partitioned ink reservoirs and, additionally, electronic contacts and a chip to communicate with the printer (only some producers insert these in the cartridge).

Whenever you try to print something, make sure that your ink level is not to low. If it is low, the ink begins to dry on the print head and printing can be hindered. A smooth flow of ink means a high quality print. If dry ink is found on the cartridge print head, gently rubbing with isopropyl alcohol on a swab or paper towel is enough to fix the problem.

In most cases, ink cartridges are very expensive. Many people prefer to use compatible ink cartridges, made by a company other than the printer manufacturer. These cartridges can sometimes match the quality, but with possible savings. Another alternative involves some modifications to allow the use of continuous ink systems that use external ink tanks. Some people even choose to use aftermarket inks. They can refill their own ink cartridge, buy aftermarket remanufactured brands, or even take them to a local refiller to refill them.

The costs of replacing ink cartridges, compared to the price of a brand new printer, amaze many of the customers. Leading printer manufacturers like Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother often loose money by selling cheap printers. They must recover these losses and make a profit by selling very expensive cartridges over the life span of the printer. Because companies producing aftermarket ink cartridges take away a part of their profit, major printer manufacturers have taken action against them. Some manufacturers even took legal action.

Many consumers opt to have their cartridges refilled or purchased remanufactured cartridges from third parties to save money over buying new cartridges. This is much cheaper (as you need only buy the ink and some other small raw materials), and a whole industry has grown up around this idea. There are several qualities and types of refilling, some of them being safe and successful, while other types can ruin the printer and/or give bad quality prints. Options include taking empty cartridges to "refillers" or "remanufacturers" who pump in new ink, and buying store-branded ink.

The cheapest way to get a filled cartridge is to refill it yourself. Almost all cartridges have instructions on how to use and refill them available on the Internet. The Internet can also provide a list of bulk ink sellers that offer pints, quarts, and even gallons of ink. A pint (473 ml) can fill up to 17 large ink cartridges of 27 ml capacity.

Generally speaking, Brother, Canon, Dell, HP, and Lexmark cartridges are not difficult to refill (sometimes a syringe and ink are enough), while Epson cartridges usually require the additional purchase of a chip resetter to reset the counter chip inherent in the Epson cartridges. However, since it involves handling ink, the refill process can be inherently messy until some experience has been acquired.

Laser/toner cartridges found as "compatible" are, in most of the cases, refilled cartridges. However, you can find many third-party newly manufactured cartridges. On the other hand, inkjet cartridges sold as "compatible" are newly produced. "Remanufactured" inkjet cartridges have been used by consumers and then refilled by a third party. Be very careful what you buy. Used cartridges may not work as newly manufactured ones. - 15790
