Changing an HP ink cartridge takes about five minutes once you know where to look

Most HP printers hold ink cartridges in a carriage that slides left and right inside the printer. To change a cartridge, you turn off the printer, open the access door, wait for the carriage to move to the center, remove the old cartridge by pressing down on it, and slide a new one in until it clicks. The whole process is the same whether you have a desktop inkjet, an all-in-one, or a photo printer — the parts are just in different places depending on your model.

The most common mistake is trying to change a cartridge while the printer is on. HP printers move the carriage to a safe position only when you shut them down, so starting with the power off saves you from jamming the mechanism or spilling ink.

Key Takeaways

  • Always turn off your HP printer completely before opening it or touching any cartridges.
  • The ink carriage will move to the center of the printer on its own once you power it down — wait for it to stop moving before you open the access door.
  • Press down on the cartridge you want to remove until you hear or feel a click, then pull it straight out toward you.
  • New cartridges have a plastic tape or seal on the bottom that you must peel off before inserting them, or the printer will not recognize them.
  • If your printer shows an error after you install a new cartridge, turn the printer off and back on to let it reset and detect the new cartridge.

Step-by-step: Removing and installing a cartridge

Step 1: Turn off the printer and wait. Press the power button on your HP printer and let it shut down completely. Wait 10 to 15 seconds after the lights go out. The carriage inside will move to the center position automatically — you will hear a quiet mechanical sound as it does. Do not open the printer while this is happening.

Step 2: Open the access door. Lift the top cover or access panel of your printer. On most HP inkjets, this is the hinged lid that covers the paper tray area. On some all-in-one models, you may need to open a side panel instead. The carriage should now be visible in the center of the printer, with the cartridges standing upright in a row.

Step 3: Identify which cartridge to replace. HP cartridges are usually labeled with their color or number on the top. Black cartridges are typically on one end, and color cartridges (cyan, magenta, yellow) are next to them. If you are not sure which one is empty or low, check your printer's display screen — it usually shows which cartridge needs replacing, or you can look at the cartridge itself to see if the ink level window is empty.

Step 4: Press and remove the old cartridge. Push down on the cartridge you want to remove. You will feel it click or snap down slightly. Once it clicks, pull the cartridge straight toward you and out of its slot. Do not twist or angle it — straight out is the correct direction. Set the old cartridge aside on a paper towel in case there is any ink residue.

Step 5: Prepare the new cartridge. Look at the bottom of the new cartridge. You will see a plastic tape, foil seal, or protective cover. Peel this off completely and throw it away. This seal keeps the cartridge dry during shipping, and if you leave it on, the printer will not recognize the cartridge or will show an error. Check that the cartridge itself is not cracked or damaged.

Step 6: Insert the new cartridge. Hold the new cartridge upright and slide it into the empty slot at an angle, with the top of the cartridge tilted slightly away from you. Push it straight in until it clicks into place. You should hear or feel a definite snap. The cartridge should sit flush with the others in the carriage — if it is sticking up higher, it is not fully seated and you need to push it in further.

Step 7: Close the access door and turn on the printer. Lower the top cover or close the side panel. Press the power button to turn the printer back on. The printer will beep or show a message as it detects the new cartridge. This detection process takes 30 to 60 seconds. Do not interrupt it or open the printer again during this time.

What to do if the printer shows an error after you install a new cartridge

If your HP printer displays a message like "Cartridge not detected," "Cartridge problem," or "Install cartridge," the most common cause is that you did not remove the plastic seal from the bottom of the new cartridge. Turn off the printer, open the access door again, and check the bottom of the cartridge you just installed. If you see any plastic, foil, or tape, peel it off completely and close the printer. Turn it back on and wait for the detection cycle to finish.

If the seal was already off and the error persists, try removing the cartridge and reinserting it. Sometimes a cartridge does not seat all the way on the first try. Push it in firmly until you hear the click, close the door, and power on the printer again. If the error continues after a second attempt, the cartridge itself may be defective — contact HP support or try a different cartridge to confirm.

Occasionally an HP printer will show a cartridge error even though the cartridge is installed correctly. In this case, turn off the printer, wait 30 seconds, and turn it back on. This reset often clears the error and allows the printer to detect the cartridge properly.

Genuine HP cartridges versus third-party cartridges

HP cartridges sold under the HP brand name are made by HP and come with a full warranty. Third-party cartridges made by other manufacturers (sometimes called compatible or remanufactured cartridges) are cheaper but may not work with all HP printers, and some HP printers will show warnings or errors when you use them. The installation process is identical — you remove and insert them the same way — but HP does not may provide they will work or that they will not damage your printer.

If you buy a third-party cartridge and your printer rejects it, remove it and try a genuine HP cartridge instead. This will tell you whether the problem is the cartridge itself or your printer's compatibility with that brand.

Where to find the right cartridge number for your printer

HP cartridges are numbered, and you need the correct number for your specific printer model. You can find your cartridge number in three places: on the cartridge itself (printed on the side or top), in your printer's manual, or on HP's website by entering your printer model number. Common HP cartridge numbers include 61, 62, 63, 65, 67, 302, 304, 305, and 364, but your printer may use different ones.

Before you buy a replacement cartridge, write down your printer model number (usually found on a sticker on the back or bottom of the printer) and search for it on HP.com or your printer's manual. This takes two minutes and prevents you from buying the wrong cartridge.

How often you need to change cartridges

How long an ink cartridge lasts depends on how much you print. A standard HP cartridge may last anywhere from a few weeks to several months in a home office, while a high-capacity cartridge lasts longer. Your printer will show you the ink level on its display screen or through HP's software on your computer. Most people change a cartridge when the printer shows a low-ink warning or when printing becomes faint or streaky.

If you print very little, cartridges can dry out even if they are not empty. If your printer has been unused for more than a month and the cartridges feel hard or the nozzles are clogged, you may need to replace them anyway. Running the printer's cleaning cycle (found in the maintenance menu) can sometimes restore a clogged cartridge, but replacement is often faster.

Frequently Asked Questions

Can I use my HP printer while a cartridge is being detected?

No. After you install a new cartridge and turn on the printer, wait for the detection cycle to finish before you try to print. This usually takes 30 to 60 seconds. If you send a print job during detection, the printer may cancel it or show an error. Wait until the printer beeps or the screen returns to normal, then you can print.

What should I do with the old cartridge after I remove it?

You can throw it in the trash, but many people recycle or refill them. Some retailers like Best Buy and Staples accept used HP cartridges for recycling. If you want to refill the cartridge yourself, you can buy refill kits online, but this is messy and may void your printer's warranty. For most people, buying a new cartridge is simpler.

Why does my printer say the cartridge is low when I just installed it?

This usually means the cartridge you bought is a standard-capacity cartridge rather than a high-capacity one, or the printer's counter did not reset properly. If you installed a brand-new cartridge and the printer immediately shows low ink, turn the printer off and back on. If the message persists, the cartridge may be defective — try a different one or contact HP support.

Do I need to clean the cartridge contacts before I install a new one?

No, not usually. The contacts on the cartridge and inside the printer are designed to work without cleaning. If your printer shows a cartridge error even after reinserting the cartridge, you can gently wipe the gold contacts on the bottom of the cartridge with a dry, lint-free cloth, but this is rarely necessary for new cartridges.

Can I change a cartridge while the printer is printing?

No. Always turn off the printer completely before opening it or removing a cartridge. If you open the printer while it is printing or in standby mode, you may damage the carriage mechanism or spill ink inside the printer. Wait for any print job to finish, then power down the printer before you proceed.
