How does an ink cartridge work ?

by Andrew James

An ink cartridge is a changeable component of an ink jet printer. It contains the ink that is spread on paper during printing and sometimes the print-head itself. Each ink cartridge contains one or more partitioned ink reservoirs and certain manufacturers also add electronic contacts and a chip that communicates with the printer.

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.

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.

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 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.

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.

If you consider refilling your cartridge you should know that Brother, Canon, Dell, HP, and Lexmark cartridges are quite easy to refill. Some of the cartridges can even be refilled with a simple syringe. However, Epson cartridges are usually harder to refill as these cartridges need a chip resetter. This resetter resets the counter chip embedded in the cartridge. Because it requires you to handle ink directly, the refill process can be tricky and you will need some experience until you will do it clean.

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.
