The basic steps: open, remove, insert, close

Replacing an HP ink cartridge takes about five minutes and requires no tools. Turn off your printer, open the access door on the front or top (depending on your model), wait for the cartridge holder to move to the center, then press down on the cartridge you want to replace until it clicks and pops out. Slide the new cartridge in at a 45-degree angle, press down until it clicks into place, and close the door. Your printer will recognize the new cartridge automatically.

The exact location of the access door and the number of cartridges varies by model. Some HP printers have one cartridge that prints in black only; others have separate black and color cartridges. A few high-volume models use tanks instead of cartridges. Check your printer's model number on the back or bottom, then look up the manual on HP's support website to confirm which cartridges your specific printer uses.

Key Takeaways

  • Turn off the printer before opening it, and wait for the cartridge holder to stop moving before you touch anything inside.
  • Push down on the cartridge until it clicks and springs out; do not pull it sideways or force it.
  • Insert the new cartridge at a 45-degree angle and press down until you hear a second click that means it is locked in place.
  • Your printer will detect the new cartridge and may run a brief cleaning cycle the first time you print.
  • Keep the plastic tape on the new cartridge's nozzle until the moment you insert it; removing it early wastes ink.

Finding the right cartridge for your printer model

HP cartridges are not universal. A cartridge made for an HP DeskJet will not fit an HP OfficeJet, and a cartridge for an older model will not work in a newer one. The cartridge number is printed on the side of the cartridge itself — it usually starts with "HP" or a number like "62" or "304" — and also appears in your printer's manual.

The easiest way to find the correct cartridge is to search your printer's model number plus "cartridge" on HP's website or on a retailer's site. HP's site will show you which cartridges are compatible. If you have lost the manual, your model number is usually on a sticker on the back of the printer or inside the cartridge door. Write it down before you shop.

Removing the plastic tape and protective seal

New HP cartridges come with a plastic tape covering the nozzle — the small opening where ink comes out. This tape must stay on until you are ready to insert the cartridge. If you remove it too early, the nozzle will dry out and the cartridge may not print properly.

Peel the tape off just before you slide the cartridge into the printer. The tape is usually bright yellow or orange so you cannot miss it. Some cartridges also have a foil seal under the tape; remove both. If you accidentally remove the tape and then decide not to use the cartridge right away, you can tape it back on with regular masking tape to keep the nozzle moist, but it is better to install it when ready.

What to do if the cartridge does not click into place

If you push down and do not hear a click, the cartridge is not fully seated. Remove it and try again, making sure you are inserting it at the correct angle — usually 45 degrees, though some models use a different angle. Check your manual if you are unsure. The cartridge should slide in smoothly; if it feels stuck, do not force it.

If the cartridge still will not lock, remove it and inspect the metal contacts on the back of the cartridge and the contacts inside the printer. Wipe both with a dry, lint-free cloth. Dust or ink residue can prevent a good connection. Reinsert the cartridge and press down firmly until you feel the click. If it still does not work, the cartridge may be defective; try a different one if you have a spare, or contact the retailer.

Handling old cartridges and avoiding ink spills

When you remove an old cartridge, have a paper towel ready. Even empty cartridges can have a small amount of ink inside, and the nozzle may be wet. Place the old cartridge on the paper towel when ready after you remove it. Do not set it nozzle-down on a clean surface.

Many retailers and manufacturers will take old cartridges back for recycling. HP has a mail-back program through its website where you can print a shipping label and send cartridges back for free. Some office supply stores also accept empty cartridges. Throwing them in the trash is legal, but recycling keeps plastic and metal out of landfills and may recover some of the materials inside.

Why your printer may run a cleaning cycle after you install a new cartridge

After you close the cartridge door, your printer may beep and display a message saying it is running a cleaning cycle or initializing the cartridge. This is normal and usually takes two to five minutes. The printer is priming the nozzles with ink so they are ready to print. Do not turn off the printer during this cycle.

If the cleaning cycle fails or the printer displays an error message, turn off the printer, wait 30 seconds, and turn it back on. If the error persists, remove the cartridge, check that the plastic tape is completely off, and reinstall it. Most errors clear after a second attempt. If your printer continues to show an error after you have reinstalled the cartridge twice, the cartridge may be defective.

Frequently Asked Questions

Can I use third-party or refilled cartridges in my HP printer?

Yes. HP printers will accept third-party and refilled cartridges, though HP does not warrant them and some printers may display a warning message. Third-party cartridges are usually cheaper than HP brand cartridges. Refilled cartridges are old cartridges that have been emptied and refilled with ink; they work but may have lower page yields than new cartridges.

What does it mean if my printer says the cartridge is not recognized?

This usually means the cartridge is not fully seated or the contacts are dirty. Remove the cartridge, wipe the metal contacts on the back with a dry cloth, and reinstall it. If the message persists, try a different cartridge if you have one. If all cartridges show the same error, the printer's cartridge reader may need service.

How do I know if a cartridge is empty?

Your printer will display a low-ink or out-of-ink message on the screen or control panel. Some printers also show a light on the cartridge itself. You can also remove the cartridge and look through the transparent plastic window on the side to see how much ink is left. When the ink level reaches the line marked "low," it is time to order a replacement.

Do I need to turn off the printer before replacing a cartridge?

Yes. Always turn off the printer before opening the cartridge door. This prevents the printer from moving the cartridge holder while your hand is inside and protects the internal components from accidental damage.

What if I put the cartridge in backwards?

The cartridge will not fit. HP cartridges are designed to go in only one way — the nozzle end goes in first, and the cartridge angles downward as you push it in. If you are having trouble inserting it, you likely have the angle wrong. Check your manual for the correct angle for your model and try again.
