Ink cartridges: How do they work ?
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.
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.
Recently, many printer owners prefer to refill their used cartridges or even buy remanufactured cartridges from third parties rather than buying expensive new cartridges. Since they only need to buy the ink and a few other small raw materials, it is much cheaper and quality is almost the same. Customers can find different qualities and types of refilling. However, some of them can damage the printer and lead to low quality prints. People take their empty cartridges to refillers or remanufacturers, or simply buy store branded ink.
Another option is for the consumer to refill the cartridges. Instructions for most cartridges are available on the web, as well as sources who sell “bulk ink” in pints, quarts, and even gallons. This can be extremely cost effective if the consumer is a heavy user of cartridges. One pint (473 ml) is sufficient ink to fill approximately 15 to 17 large cartridges of a typical 27 ml capacity. At the price of an original cartridge, you can buy at least one pint of ink.
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 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.
