HP Smart Tank Refill – Complete Step-by-Step Guide (2026)
Save up to 90% on ink costs by correctly refilling your HP Smart Tank printer. This expert guide covers every model, every ink color, and every common mistake — so you do it right the first time.
The HP Smart Tank series was designed around one core promise: ultra-low-cost printing with easy, mess-free ink refills. Unlike traditional cartridge printers, Smart Tank models use refillable integrated ink tanks that hold enough ink to last months — even for moderate-to-heavy print volumes. But to get the most out of the system, you need to refill correctly.
This guide covers everything: which ink bottles to buy, how to refill each color without spills, how to reset ink level alerts, and what to do when things go wrong. Whether you own an HP Smart Tank 500, 515, 530, 570, 615, 720, or 750, you’ll find everything you need right here.
To refill an HP Smart Tank printer, open the front ink tank door, remove the cap on the tank matching your ink color, align the HP ink bottle nozzle over the tank opening, and squeeze gently until the ink reaches the MAX fill line. Replace the cap securely, close the door, then reset ink levels via the HP Smart app or printer control panel. Use only genuine HP GT51/GT52 or HP 31/32S ink bottles for your specific model.

What You Need Before You Start Refilling
- The correct HP ink bottle(s) for your Smart Tank model (see table above)
- A clean, flat surface with some newspaper or paper towels laid down
- Latex or rubber gloves (ink stains skin and fabric)
- A lint-free cloth or paper towel for any spills
- Your printer powered on and idle (not mid-print)
Step-by-Step: How to Refill HP Smart Tank Ink
Open the Ink Tank Access Door
On the front of your HP Smart Tank printer, locate and open the ink tank access door. On most models this is a small panel on the front-left side. The tanks are color-coded: Black (left), Cyan, Magenta, Yellow (right). Let the printer sit idle for 30 seconds after opening.
Remove the Tank Cap Carefully
Locate the tank you need to refill. Twist the colored tank cap counter-clockwise and lift it off. Set the cap aside on a clean surface — do not lose it. The tank opening is small, so work slowly and deliberately.
Prepare the HP Ink Bottle
Remove the ink bottle cap and the foil seal. Ensure the color matches the tank you’re filling — the bottle and cap will both be color-coded. Do not shake the bottle. Hold it upright to prevent premature drips.
Insert and Fill the Tank
Align the bottle nozzle with the tank opening and press down gently until you feel it seat. Squeeze the bottle slowly and steadily — the ink will flow automatically. Stop filling when the ink level reaches the MAX fill line. Do not overfill, as this can cause leaks and head damage.
Replace the Tank Cap Firmly
Remove the ink bottle and immediately replace the tank cap. Press down and twist clockwise until it clicks or feels snug. Wipe any ink residue around the tank opening with a lint-free cloth. Repeat Steps 2–5 for any other colors that need refilling.
Close the Access Door and Reset Ink Levels
Close the ink tank access door firmly. The printer may prompt you to confirm the refill. If it doesn’t automatically reset, open the HP Smart App, navigate to Printer Settings → Ink Levels → Reset Ink Levels, and confirm. Alternatively, use the printer’s control panel touchscreen if available.
Run a Printhead Cleaning Cycle
After refilling, especially if the tank was running very low or empty, run one printhead cleaning cycle. Go to HP Smart App → Printer Maintenance → Clean Printheads or navigate to the printer’s Settings menu. Print a test page to confirm quality before regular use.

Common HP Smart Tank Refill Problems & Fixes
Ink Not Flowing From the Bottle
Ensure the foil seal has been completely removed from the bottle nozzle. Check that the bottle is fully seated in the tank port. If ink still won’t flow, gently squeeze the bottle while holding it upright. Some bottles require a slight break-in squeeze to initiate flow.
Ink Level Not Updating After Refill
The HP Smart Tank may not auto-detect refills. Open the HP Smart App and navigate to Printer Settings → Ink Levels and manually update or reset the level for the refilled color. A printer restart often resolves this automatically.
Print Quality Is Poor After Refilling
Run 2–3 printhead cleaning cycles via the HP Smart App or control panel. Print a diagnostic page after each cycle. If quality doesn’t improve, visit our HP Printhead Cleaning Guide for advanced troubleshooting or contact our support team.
Ink Spilled During Refill
Clean immediately with cold water and a damp cloth on skin or fabric. For printer surfaces, use a lint-free cloth moistened with water. Avoid using cleaning chemicals near ink tank openings as they can contaminate the ink system.
Overfilled Tank / Ink Leaking
Never fill above the MAX line. If overfilled, use a syringe or dropper to carefully remove excess ink. Wipe down the tank area and allow to settle for 10 minutes before printing. Contact our HP Printer Troubleshooting service if leaking continues.
