How does an ink cartridge work ?
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).
Before printing anything, the ink level must be checked. If it is too low, ink may dry on the print head and lead to low quality prints. The ink must have a smooth flow in order to produce high quality prints. To clean the dried ink from the print head, it is strongly advised to gently rub the head with isopropyl alcohol on a swab or 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.
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 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.
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).
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.
