How to Replace Ink or Toner Cartridges (Step by Step)

Before you start

Have your replacement cartridge ready and sealed until the moment you install it — exposed ink nozzles and toner drums degrade with air exposure.

Inkjet cartridges

1. Open the printer's front access panel. The cartridge carriage usually moves to the center automatically.
2. Press down gently on the old cartridge until it clicks and releases, then pull it straight out.
3. Remove the orange/pink protective tape from the new cartridge's contacts — don't touch the copper contacts or the nozzle.
4. Insert at an angle, then press down until it clicks into place.
5. Close the panel. Most printers run a brief alignment/cleaning cycle automatically — let it finish before printing.

Laser toner cartridges

1. Open the top or front cover and pull out the old toner cartridge by its handle.
2. Gently shake the new cartridge side to side 5-6 times to redistribute toner evenly before removing its seal.
3. Pull the sealing strip/tape straight out in one motion — don't stop halfway.
4. Slide the cartridge in until it seats and the cover closes without resistance.

If prints look streaky afterward

Run the printer's built-in cleaning/alignment utility (usually in the printer's own menu or in the manufacturer's printer software on your computer) before assuming the cartridge is faulty.
