The basic steps to swap out a cartridge

Replacing an HP ink cartridge takes about five minutes and requires no tools. Turn on your printer, open the access door on the front or top (the location varies by model), wait for the cartridge holder to move to the center, and then press the cartridge down slightly until you hear a click—this releases it. Slide the old cartridge out at an angle, remove the new one from its packaging, peel off the plastic tape on the bottom, and insert it at the same angle until it clicks into place. Close the door and your printer will recognize the new cartridge automatically.

The exact location of the access door depends on your printer model. On desktop inkjet printers like the HP DeskJet or OfficeJet series, it is usually on the front panel below the paper tray. On larger multifunction printers, it may be on the top. Check the physical printer first—most have a small arrow or icon showing where to open. If you cannot find it, your printer's model number (printed on the back or inside the door frame) will let you search HP's support site for a diagram specific to your machine.

Key Takeaways

  • Open the printer's access door and wait for the cartridge holder to center itself before removing or inserting any cartridge.
  • Press the old cartridge down until it clicks, then slide it out at an angle; insert the new one the same way until you hear a second click.
  • Remove the plastic tape from the bottom of the new cartridge before installation, or the printer will not recognize it.
  • Your printer model number, found on the back or inside the door frame, will help you locate the exact cartridge slot if your model has multiple colors in separate cartridges.

Finding the right cartridge for your printer

HP cartridges are model-specific, so you need to know which one your printer uses. The easiest way is to look at the cartridge currently in your printer—the model number is printed on the side. It usually starts with "HP" followed by a number like "65" or "304" or "912". Write this number down or take a photo.

If you have already removed the old cartridge and cannot find the number, check your printer's manual or search your printer's model number on HP's website. The support page will list all compatible cartridges. You can also check the packaging of any cartridge you have bought before—HP keeps the same cartridge numbers across batches, so an old box will tell you what to buy.

HP makes both standard and high-capacity versions of most cartridges. A standard cartridge is cheaper upfront but runs out faster. A high-capacity cartridge costs more but prints more pages before needing replacement. Check which one your printer originally came with, or look at the page-yield number on the box—higher numbers mean more pages per cartridge.

What happens if the cartridge does not click into place

If the cartridge will not click or feels stuck, stop pushing and check three things. First, make sure you are inserting it at the correct angle—most HP cartridges go in at a slight downward angle, not straight in. Second, confirm the plastic tape on the bottom of the new cartridge is fully peeled away; if even a corner is still stuck, the cartridge cannot seat properly. Third, look inside the cartridge slot for any visible debris or a piece of the old cartridge left behind.

If the slot looks clear and the tape is off, try removing the cartridge and reinserting it slowly. You should feel it slide in smoothly and then click when it reaches the end. If it still will not click after two or three attempts, the cartridge may be defective or the printer may have a mechanical issue. Stop trying to force it—contact HP support or the retailer where you bought the cartridge for a replacement.

Recognizing when a cartridge is empty or low

Your printer will display a low-ink warning on its screen or in the software on your computer before the cartridge is completely empty. Some printers show a percentage; others show a colored bar. When you see this warning, you have time to order a replacement cartridge, but you should do so soon because printing will stop once the cartridge is truly empty.

If your printer stops printing even though the cartridge still has ink visible inside, the cartridge may be clogged rather than empty. This happens when ink dries inside the nozzles, usually after the printer sits unused for several weeks. Before replacing the cartridge, try running your printer's cleaning cycle—this is usually found in the printer settings or the HP software on your computer under "Maintenance" or "Tools". If cleaning does not restore printing, then replace the cartridge.

Storing extra cartridges so they stay usable

Keep unopened cartridges in their original sealed packaging in a cool, dry place. The plastic tape on the bottom keeps air out and prevents the ink from drying. Store them upright, not on their side, and away from direct sunlight or heat sources like radiators or sunny windowsills. A shelf in a closet or cabinet is ideal.

Once you open a cartridge and install it, use it within a reasonable time—do not let an installed cartridge sit unused for more than a few months. If you know your printer will not be used for an extended period, consider removing the cartridge and storing it in its original packaging. When you turn the printer back on, it may ask you to run a cleaning cycle, which is normal and takes a few minutes.

What to do with the old cartridge

Do not throw ink cartridges in the trash. Many retailers that sell HP cartridges, including Best Buy, Staples, and Office Depot, have cartridge recycling programs at the register. Some will even give you a small discount on your next purchase if you bring in an old cartridge. HP also runs a mail-back recycling program through its website—you can print a prepaid shipping label and send cartridges to them for free.

If you have a large number of old cartridges, check whether your city or county has an electronics recycling center that accepts printer supplies. Ink cartridges contain materials that can be recovered and reused, so recycling keeps them out of landfills.

Frequently Asked Questions

Can I use a third-party or refilled cartridge instead of an HP cartridge?

Yes, third-party and refilled cartridges work in most HP printers, though HP does not may provide print quality or reliability with non-HP cartridges. Some printers may display a warning message but will still print. If you use a non-HP cartridge and experience poor print quality or the cartridge leaks, switch back to an HP cartridge to rule out compatibility as the cause.

Why does my printer say the cartridge is not recognized?

This usually means the plastic tape on the bottom of the new cartridge was not fully removed, or the cartridge is not seated all the way in the slot. Remove the cartridge, check that all plastic is peeled away, and reinsert it firmly until you hear the click. If the message persists, the cartridge may be defective—contact the retailer for a replacement.

Do I need to replace all cartridges at once, or just the one that is empty?

Replace only the cartridge that is empty or low. HP printers track each color separately, so you can replace black ink without touching the color cartridges, or vice versa. Replacing only what you need saves money.

What if my printer has a single cartridge instead of separate color cartridges?

Some HP printers use a single tri-color cartridge that contains black, cyan, and magenta in one unit. When any one color runs out, you replace the entire cartridge. Check your current cartridge or your printer manual to see whether your model uses separate cartridges or a single combined one.
