Complete selection of inks specific to the printer model. These are NOT generic inks - they instead are inks designed to match the original ink supplied in your cartridge. This insures exact color matching and the same formulation as the original ink. It is not difficult to refill an inkjet cartridge. It is a simple process that takes from 5 to 10 minutes depending on which cartridge is being refilled. Steps include removing the cartridge from the printer, finding or making an entry hole in the cartridge, transferring the ink from the bottle to the cartridge, waiting a few minutes for the pressures to stabilize and then re-installing the cartridge and cleaning up. Refilling should not be messy if you are careful. You probably will get some ink on your gloves so be sure to wear them. It is best to refill in an area that is safe from damage if you do spill some ink (use common sense here - you don't want to ruin your carpet or stain your counter top if an accident occurs!). Lay down some newspapers before you start and have some paper towels handy. If you should happen to get ink on your hands a mild bleach and water solution will clean the ink off your skin. If you don't want to use bleach, Lava soap works fine with a little scrubbing. Refill Kits Bottles of Bulk Ink Printhead Cleaning Solution & Cleaning Cartridges Accessories
