Refilling an ink tank printer such as an EcoTank or MegaTank is simple and rarely messy if you go slowly. Follow your printer’s manual for your model, and use these general steps.

Before you start
- Use the ink bottles your printer specifies.
- Lay a paper towel under the printer.
- Keep the printer on a flat surface.
Step 1: Open the tank cover
Open the scanner or the tank cover as your manual describes. Find the tank that matches the color you are refilling.
Step 2: Open the tank cap and prepare the bottle
Open the tank cap. Many bottles are keyed so the right color only fits the right tank. Remove the bottle cap.
Step 3: Pour slowly
Insert the bottle nozzle into the tank and let the ink flow. Stop when the tank reaches the upper line. Do not overfill.
Step 4: Close the tank and clean up
Close the cap firmly and wipe any drops. Close the cover.
When to refill
Refill when a tank is near the lower line, not completely empty, to avoid air in the system.

Troubleshooting After Refilling
If prints look streaky after refilling, run the printer’s cleaning cycle once and print a test page. If one color is missing, check that the tank has ink and that you filled the correct tank.
Storing Ink Bottles
Keep bottles upright, closed and in a cool place away from sunlight. Check the packaging for the maker’s storage guidance.
Cleaning Spills
Ink stains fabric and surfaces. Wipe drops quickly with a damp cloth and wash hands. Keep a paper towel under the printer while you work.
Before You Start Printing Again
Close the tank caps firmly and the cover. Some printers need a short priming or alignment step after refilling; follow the on-screen prompt.
Cost
Ink bottles cost less per page than cartridges. See our EcoTank guide and cost-per-page guide.
Frequently Asked Questions

No. Fill each tank only with its matching color.
What if I overfill?
Wipe up spills and follow your manual. Do not tilt the printer.
How often do I refill?
It depends on how much you print. Check the tank levels regularly.
Bottom Line
Match colors, pour slowly, stop at the upper line and refill before a tank runs dry.
