If you've ever been told that your printer needs a new cartridge, you may have wondered what that small box actually does inside the machine.
A printer cartridge is a replaceable container that holds the ink or toner a printer uses to produce documents and images. When you send something to print, the printer draws the ink or toner from the cartridge and transfers it onto the paper to create the finished document.
There are two common types of printer cartridges.
Ink cartridges are used in inkjet printers. They contain liquid ink and are usually available as black cartridges and separate colour cartridges. Some printers use individual cartridges for cyan, magenta, yellow and black, while others combine several colours into one cartridge.
Toner cartridges are used in laser printers. Instead of liquid ink, they contain a fine powder called toner. The printer uses heat and other components to bond the toner to the paper, making laser printing particularly useful for fast, high volume document printing.
This is why it is important to know what type of printer you have before buying a replacement cartridge. An ink cartridge cannot be used in a laser printer, and a toner cartridge cannot be used in an inkjet printer.
Another thing to consider is whether the cartridge is compatible with your specific printer model. Two printers from the same brand can require completely different cartridges. Using the wrong cartridge can result in poor print quality, compatibility problems or, in some situations, damage to the printing system.
You may also come across original, compatible and remanufactured cartridges. Original cartridges are produced by the printer manufacturer, while compatible cartridges are made by other manufacturers for use with particular printer models. Remanufactured cartridges are previously used cartridges that have been professionally cleaned, refilled and tested.
The cheapest cartridge is therefore not always the best choice. You need to consider print quality, page yield, reliability and how much you actually print. A cartridge that costs less but produces significantly fewer pages may not give you the savings you expected.
And if your printer is regularly telling you that the cartridge is empty, it may be time to look beyond the cartridge itself. Your printing volume, printer type and maintenance habits could all be affecting how frequently you need replacements.
