When you reuse your printer ink cartridges, you’ll be using the same casing over and over again to house the printer ink that you print with. This means that a great deal of ink is going to be passing through the unit itself and as a result, some of that ink may start to dry on the print head and nozzle of the printer cartridges. Cleaning this dry printer ink out should be able to restore your printer ink cartridge to a fully functional state once more. You will need to be very careful about how you do this, however, so that you do not damage the printer ink which you just put into your recycled printer ink cartridge.
Start by running the print head cleaning process on your printer itself. This can help to restore your printer itself to a clean state which is going to allow the best printing. If you find that you’re still having problems with getting your printer to work properly, there could be dry printer ink within the nozzle of your printer ink cartridges. Very carefully remove the nozzle from your printer ink cartridge and soak it in warm water. Thoroughly dry it on a paper towel before you reattach it to your printer ink cartridge. If you do this correctly, your refilled printer ink cartridge should quickly be able to work again and you will have a fully functional printer to use.
Nice entry and instructions for those DIYer’s out there.
It also works to blow compressed air through the print head and cartridge to help loosen up dried ink.
