Inkjet Refills
Inkjet refills are a way of refilling inkjet printer cartridges that do away with the need to buy a new cartridge every time your existing one runs out of ink. Here, instead of simply replacing the empty inkjet cartridge with a new one you can use the refill to reload it with ink again.
In basic terms most inkjet refills will come as a pack which contains the ink refill(s) and any tools you need to refill the cartridge. This pack should be suitable for use with the type of printer/inkjet product that you currently use. It should also come with full instructions on how to refill your cartridges.
Most inkjet refills are easy to use. Here you simply use an injection needle or other supplied tool to take ink out of the refill pack and to inject it into your cartridge. If you are refilling a colour ink cartridge then you may have to inject a variety of coloured inks - again, following the instructions here will give you the best results.
It is often becoming much more common to use inkjet refills nowadays rather than to buy new cartridges. People have got into the habit of doing this because refilling a cartridge is cheaper than buying a new one and because it is better from an environmental perspective.
