Remove the old cartridge and install the new one

Replacing an HP 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), and wait for the cartridge holder to stop moving. Gently push the cartridge toward the center until you hear a click, then pull it straight out at a slight downward angle. Do not touch the copper contacts or the nozzles on the bottom of the cartridge.

Unpack your new cartridge and remove the plastic tape and protective cap from the bottom. Some cartridges have a yellow pull-tab on top—remove that too. Slide the new cartridge into the empty slot at a 45-degree angle, then push down firmly until it clicks into place. Close the access door. Your printer will run a setup cycle, which takes one to three minutes. Do not turn off the printer during this time.

Key Takeaways

  • Turn off your printer before opening the cartridge door, and wait for the holder to stop moving before removing the old cartridge.
  • Remove all protective plastic from the new cartridge, including the yellow pull-tab and the tape covering the nozzles, before inserting it.
  • Push the cartridge down at a 45-degree angle until you hear a click, then close the door and let the printer complete its setup cycle without interruption.
  • If your printer shows a low-ink warning after replacement, the cartridge may not be fully seated—open the door and press it down again.
  • Keep the old cartridge in case you need to return it for a refund or recycling, depending on where you bought it.

Locate the cartridge slot for your printer model

The cartridge door location varies by model. On most desktop printers, it is on the front panel below the paper tray. On some all-in-one models, the door is on the top right side. Check your printer's manual or look for a small icon showing a cartridge—that marks the access point. If you cannot find the manual, search your printer's model number (usually on the back or bottom) plus "cartridge replacement" online.

Some HP printers have a single cartridge slot for black ink only, while others have two, three, or four slots for black, cyan, magenta, and yellow. Look inside the door to see how many slots your printer has and which color cartridge you need. The slots are usually labeled with color names or symbols. If you are replacing multiple cartridges, do one at a time to avoid confusion.

Understand which cartridge type your printer uses

HP makes several cartridge lines, and using the wrong type will not work. The most common types are HP 65 (used in DeskJet and ENVY models), HP 62 (older DeskJet models), HP 304 (some ENVY and OfficeJet models), and HP 952 (newer OfficeJet Pro models). Your printer's model number tells you which cartridge it needs. You can also find the correct cartridge number on the cartridge slot itself—look inside the door for a label or icon.

The easiest way to buy the right cartridge is to search your printer's model number on HP's website or on a retailer's site, then select your printer from the results. The site will show you the exact cartridge number and color you need. Buying the wrong cartridge wastes money and will not fit into your printer.

Check for error messages after installation

After the setup cycle finishes, your printer should recognize the new cartridge and clear any low-ink warnings. If you see an error message like "cartridge not recognized" or "cartridge problem," the cartridge is not fully seated. Open the door, remove the cartridge, and push it back in firmly until you hear a definite click. Make sure the cartridge is at a 45-degree angle as you insert it, not straight in.

If the error persists after reinserting, the cartridge contacts may be dirty. Remove the cartridge again and gently wipe the copper contacts on the back with a dry, lint-free cloth. Do not use water or cleaning solution. Reinsert the cartridge and run the setup cycle again. If the error still appears, the cartridge itself may be defective—contact the retailer or HP for a replacement.

Avoid common mistakes during replacement

The most frequent error is leaving protective plastic on the cartridge. The yellow pull-tab on top and the clear tape covering the nozzles must come off before installation, or the cartridge will not work. Check the cartridge packaging to see if there are multiple pieces of tape—some cartridges have tape on the side as well as the bottom.

Another common mistake is touching the copper contacts or the nozzles on the bottom of the cartridge. Oils from your fingers can block the nozzles or prevent electrical contact, causing print quality problems or cartridge errors. If you accidentally touch these parts, wipe them gently with a dry cloth before installing the cartridge. Do not use your fingers to push the cartridge in—use the top of the cartridge itself, where the plastic is thicker.

Store old cartridges and understand return options

Keep your old cartridge after removal. Many retailers offer a small refund or store credit if you return the empty cartridge, and some manufacturers run cartridge recycling programs. Check your receipt or the retailer's website to see if they accept returns. HP also has a mail-back recycling program on its website where you can send old cartridges for free.

If you bought the cartridge from a big-box retailer like Staples, Best Buy, or Walmart, ask at the customer service desk about their cartridge return policy. Some stores give store credit for returns within 30 to 60 days. If you bought online, check the seller's return policy before throwing away the packaging—you may need the original box to return the cartridge.

Frequently Asked Questions

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

Yes. Turn off the printer and wait 30 seconds before opening the cartridge door. This stops the cartridge holder from moving and prevents damage to the printer head. If the holder is still moving when you open the door, close it and wait another minute before trying again.

What if the cartridge will not click into place?

Make sure you are inserting it at a 45-degree angle, not straight in. Push down firmly on the top of the cartridge until you hear a click. If it still will not seat, remove it and check that all protective plastic has been removed from the bottom. Also verify you have the correct cartridge type for your printer model.

Can I use third-party or refilled cartridges instead of HP cartridges?

Yes, but HP printers may show warning messages about non-genuine cartridges. Third-party and refilled cartridges work in most HP printers, though print quality and reliability vary by brand. Some retailers sell compatible cartridges at lower prices. Check the product description to confirm compatibility with your printer model before buying.

How long does the setup cycle take after I install a new cartridge?

The setup cycle usually takes one to three minutes. During this time, the printer cleans the nozzles and tests the cartridge. Do not turn off the printer or open the cartridge door while the cycle is running, or you may damage the cartridge or printer head.

What should I do if my printer still shows low ink after replacing the cartridge?

The cartridge may not be fully seated. Open the door, remove the cartridge, and push it back in until you hear a click. If the warning persists, the cartridge contacts may need cleaning—gently wipe the copper contacts with a dry cloth and reinsert. If the problem continues, the cartridge may be defective and should be returned to the retailer.
