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.

Customers are often amazed of how much it costs to replace their printer cartridges compared with the price of a brand new printer. Major printer manufacturers such as Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother often loose money selling cheap printers. To recover the losses and make a profit, they sell very expensive cartridges over the life span of the printer. Because many printer manufacturers rely on selling ink and toner cartridges, some of these companies have taken action against aftermarket cartridges. Some of them even took legal action against companies manufacturing aftermarket cartridges.

Many printer owners choose to refill their cartridges or buy remanufactured cartridges from third parties over buying new cartridges. This saves them a lot of money (they only have to buy the ink and a few other small raw materials) and gets them almost the same quality. A whole industry has grown up around ink cartridge refilling. Customers can find several qualities and types of refilling. However, some are safe and successful while other types can destroy the printer or produce low quality prints. Some of the options are to take the empty cartridges to refillers or remanufacturers, or buy 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 sold as "compatible" are usually re-filled cartridges, although many third-party newly manufactured cartridges exist. Inkjet cartridges sold as "compatible" are newly manufactured cartridges. Inkjet cartridges sold as "remanufactured" are cartridges that have been used at least once by a consumer and then refilled by a third party. Note that used cartridges might not work as expected.
