Ink cartridges and how we use them

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.

Most of the time ink cartridges tend to be quite expensive, so customers started to use "compatible" ink cartridges. These cartridges are produced by companies other than the printer manufacturers. Compatible ink cartridges can come at the same quality as the original ones, depending on the manufacturing company. However, all compatible ink cartridges are cheaper than original ones. Many people use modified printers that allow the use of continuous ink systems. These printers use ink from external ink tanks. People can also use aftermarket inks to refill their cartridges, or take them to local refillers.

Consumers are often surprised at the price of replacing their printer cartridges, especially when compared with that of purchasing a brand new printer. The major printer manufacturers, Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother often break even or loose money selling printers, and expect to recoup their losses by selling expensive cartridges over the life span of the printer. Since much of the printer manufacturer's profits are made up of ink and toner cartridge sales, some of these companies have taken various actions against aftermarket cartridges. Sometimes, even legal action was taken.

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.

There is one more thing the consumer can do: refill their own cartridges. Most cartridges have instructions on how to use and refill on the Internet. Bulk ink sellers can also be found on the Internet. They offer pints, quarts, and even gallons of ink. One single pint (473 ml) can refill between 15 and 17 large cartridges (of 27 ml capacity).

Brother, Canon, Dell, HP, and Lexmark cartridges ink cartridges are very easy to refill manually. By using a simple syringe, you can fill some of them. All you need is ink. However, Epson cartridges are usually hard to refill and need a chip resetter. This tool resets the counter chip inside the cartridge. Refilling process can be messy as it involves handling ink directly. Some experience is needed to make the process as clean as possible.

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. - 15634
