How to Refill Ink Cartridges?

Refilling the ink cartridges is a messy job. Ensure that you inject the ink carefully into the hole.Clean the excess ink on the cartridge.

In case you miss out to do the above steps, it may result in poor print quality such as blurred text, blank spots and ink smears.

Gather compatible ink cartridges, a piece of paper, needle and a syringe. Take out the refillable ink cartridge out of its slot.

Place it on a piece of white paper. Check out the tri-color cartridge. Examine the color in the various chambers of the cartridge.

Peel off the label on top. Check out the depleted ink in it. You can examine it by piercing the needle into the hole.

Based on the cartridge size, amount of ink inserting into it varies. For XL cartridge, fill up to 8 ml of black ink.

For normal cartridge, fill 2.5 ml of ink into it. Locate the refill hone on the top of the cartridge.

For a tri-color cartridge, you can find yellow in the top middle, magenta in the middle left and cyan in the middle right.

Pierce the needle into the hole until the ink starts injecting. While inserting, ensure that there is no air bubbles in it.

These air bubbles can block the ink from flowing properly to the printhead once reinstalled. Once the ink starts to overflow, take out the syringe.

Stick the refill hole with clear tape. Make use of paper towels and a small amount of water to clean the excess ink in it.

Now, reinstall the ink cartridge into their respective slots. Use an automated tool to clean the print head to wipe off the dried ink .

In case you add more ink and then reinstall it, the printer may not detect the ink. It shows low ink message on the control panel.

To overcome the issue, reset the ink cartridge. Cover the contacts with a clear tape and then reinstall it back to its respective slot.

Try to print a test page. Take out the cartridge and then remove the tape. After that, insert the cartridge back to the printer.

Now, the printer recognized the refilled cartridge. Make an attempt to print from the printer to ensure that the cartridge is properly installed.
