Where to find and remove your old cartridge

Your HP printer stores ink cartridges in a plastic holder called the carriage, which sits inside the printer. To reach it, open the printer's top cover or access panel — the exact location depends on your model, but it is usually on top or on the front. Once open, you will see the carriage move to one side of the printer automatically. If it does not move within a few seconds, press the power button once.

Look for the cartridge you need to replace. HP printers typically use either one cartridge (black only) or four cartridges (black, cyan, magenta, and yellow). Each cartridge sits in its own slot and is held in place by a small clip or latch. The cartridge will have a colored label or band that matches its color — black cartridges are labeled black, cyan ones are labeled cyan, and so on.

To remove the cartridge, push down on the clip or latch holding it in place. The cartridge will pop up slightly. Grip it by the sides (not the nozzle at the bottom) and pull it straight out toward you. Set it aside — do not touch the copper contacts on the back or the nozzle on the front, as oil from your skin can cause printing problems.

Key Takeaways

  • Open your printer's access panel and wait for the carriage to move to the side before removing any cartridge.
  • Push down the clip holding the old cartridge, then pull it straight out by the sides only.
  • Remove the plastic tape from the new cartridge before inserting it, or your printer will not recognize it.
  • Insert the new cartridge at a slight angle, then push down until you hear or feel a click, which means it is locked in place.
  • Close the access panel and run a cleaning cycle if your printer offers one, especially if the cartridge sat unused for months.

Preparing and installing the new cartridge

Remove the new cartridge from its box and look for a piece of plastic tape or a plastic cap covering the nozzle at the bottom. This tape protects the cartridge during shipping and storage. Peel off the entire tape — if you leave it on, the printer will not be able to detect the cartridge and will display an error message. Some cartridges also have a small plastic clip on the back; you can leave this in place.

Hold the new cartridge at a slight angle (about 45 degrees) and slide it into the empty slot. The cartridge should fit into the slot smoothly. Once it is partway in, push down firmly until you hear a click or feel resistance — this means the cartridge is locked into the carriage and the contacts are making a proper connection. Do not force it; if it does not slide in easily, remove it and check that you are inserting it into the correct slot for that color.

Close the printer's access panel. Most HP printers will automatically detect the new cartridge and may display a message on the screen or on your computer. Some models will ask you to confirm the cartridge color or run a cleaning cycle. If your printer offers a cleaning cycle, run it — this is especially important if the cartridge has been sitting in storage for several months, as it helps clear any dried ink from the nozzles.

What to do if the printer does not recognize the cartridge

If you see an error message saying the cartridge is not recognized or is not genuine, the most common cause is that you did not remove the plastic tape completely. Power off the printer, open the access panel again, and remove the cartridge. Check the nozzle area at the bottom and the sides for any remaining tape or plastic. Peel away anything you find, reinsert the cartridge, and close the panel.

If the cartridge is still not recognized after removing all tape, the copper contacts on the back of the cartridge may be dirty. Power off the printer, remove the cartridge, and use a dry, lint-free cloth to gently wipe the copper contacts on the back. Do the same for the metal contacts inside the carriage slot. Reinsert the cartridge and power the printer back on.

A third possibility is that the cartridge slot itself is damaged or the carriage is not moving properly. If the cartridge clicks into place but the printer still shows an error, try a different cartridge slot if your printer has multiple slots. If no cartridge works in that slot, the printer may need service — contact HP support with your printer model number.

Handling cartridges that are low or empty

Most HP printers will alert you when a cartridge is running low on ink, either through a message on the printer's screen or through software on your computer. You do not have to wait until the cartridge is completely empty to replace it — in fact, replacing it early can prevent print quality from dropping. However, some printers will stop printing entirely once a cartridge is empty, even if other colors still have ink.

If a cartridge is empty but you do not have a replacement on hand, you have two options. You can order a new cartridge and continue using the printer for other colors (if it is a multi-cartridge model). Alternatively, some HP printers allow you to temporarily remove an empty cartridge and continue printing in black and white or in reduced color mode — check your printer's manual to see if this is supported.

When you do replace an empty cartridge, follow the same steps as above: remove the old one, peel the tape from the new one, and insert it until it clicks. The printer will recognize the new cartridge when ready and resume normal printing.

Storing cartridges and avoiding common mistakes

If you buy cartridges in advance, store them in a cool, dry place away from direct sunlight. Keep the plastic tape on the nozzle until you are ready to use the cartridge — this tape prevents the ink from drying out. Cartridges stored without the tape can dry out in as little as a few weeks, especially in warm or dry climates, and will not print properly when you try to use them.

Do not touch the nozzle at the bottom of the cartridge or the copper contacts on the back. Oil from your skin can clog the nozzle or interfere with the electrical connection. If you accidentally touch these areas, wipe them gently with a dry, lint-free cloth before installing the cartridge.

Avoid mixing cartridge types. HP cartridges come in standard, high-yield, and extra-high-yield sizes, and they are not interchangeable within the same printer model. Check your printer's manual or the box of your new cartridge to confirm it is the correct type for your model. Using the wrong cartridge can damage the carriage or prevent the cartridge from being recognized.

When to clean the print head instead of replacing the cartridge

If your prints are coming out faded, streaky, or missing colors, the problem is usually not the cartridge itself but the print head — the part that sprays ink onto the paper. Before you replace a cartridge, run your printer's cleaning cycle. Most HP printers have this option in the settings menu or in the printer software on your computer. A cleaning cycle uses a small amount of ink to flush the nozzles and restore print quality.

If cleaning does not fix the problem and the cartridge still has ink in it, the print head may need a deeper cleaning. Some HP printers offer a "deep clean" or "nozzle check" option in addition to the standard cleaning cycle. Run this option and then print a test page. If the test page still shows problems, the print head may be permanently clogged and the printer may need service.

Frequently Asked Questions

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

Yes, many HP printers will accept third-party and refilled cartridges, though HP does not recommend them and some printers may display a warning message. Third-party cartridges are often cheaper but may have lower print quality or shorter lifespan. If you use a third-party cartridge and it does not work, remove it and reinstall an HP cartridge to rule out compatibility issues.

Why does my printer say the cartridge is not genuine?

HP printers check cartridges using a chip on the back of each cartridge. This message usually means the cartridge is refilled, third-party, or the chip is damaged. If you are using a genuine HP cartridge and still see this message, remove the cartridge, wipe the copper contacts with a dry cloth, and reinsert it. If the message persists, the printer's cartridge reader may need cleaning or service.

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

Many retailers that sell ink cartridges, including office supply stores and some electronics stores, accept empty cartridges for recycling at no charge. Some manufacturers also offer mail-back programs. Do not throw cartridges in the trash — they contain plastic and metal that can be recycled, and some contain residual ink that should not go to a landfill.

How do I know which cartridge color goes in which slot?

Each slot in the carriage is labeled with a color — look for small colored labels or icons next to each slot. The cartridge itself also has a colored label or band. Match the color on the cartridge to the color label on the slot. If the labels are worn or hard to read, check your printer's manual or the HP website for your specific model number.

Can I leave a cartridge out of the printer if I do not use that color?

This depends on your printer model. Some HP printers require all cartridge slots to be filled and will not print if a slot is empty. Others allow you to remove a cartridge and continue printing in other colors. Check your printer's manual to see which applies to your model. If your printer requires all slots to be filled, you can buy a low-cost black cartridge or a color cartridge and leave it in the unused slot.
