Ink cartridges: How do they work ?

By Andrew James

An inkjet cartridge is the replaceable component of an inkjet printer that contains the ink used when printing. The ink cartridge can also contain the print head itself. Every ink cartridge is made up from one or more partitioned ink reservoirs and some producers also insert electronic contacts and a chip that transmits information to the printer.

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 by rubbing gently with isopropyl alcohol on a swab or folded paper towel.

Often, ink cartridges are extremely expensive, so many people started to use compatible ink cartridges produced by a company other than the printer manufacturer. Depending on the company, compatible ink cartridges can sometimes be of the same quality as original cartridges and save you some money. Some people have made some modifications to the printer to allow the use of continuous ink systems. In these cases, the ink comes from external ink tanks. Another alternative is to use aftermarket inks to refill your own cartridge or take it to a local refiller.

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 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. - 15431
