Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable. Use the single-cartridge mode to operate the HP ENVY 4520 series with only one ink cartridge. The singlecartridge mode is initiated when an ink cartridge is removed from the ink cartridge carriage. During single-cartridge mode, the printer can copy documents, copy photos, and print jobs from the computer.
Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. Unlike other inkjet manufacturers, HP designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed. HP recommends that you use original new HP ink cartridges.
XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print at least double the pages of a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.
Which ink cartridges do I need for my HP ENVY 4520 All-in-One series Printer?

Replace the cartridges
1. Press the Power button to turn on the printer, if it is not already turned on. Wait until the product is idle and silent before continuing.
2. Load plain white paper in the input tray.
7. Hold the ink cartridge by its sides with the nozzles toward the printer, then slide the ink cartridge forward into the slot. Then close the latch until it clicks to secure the ink cartridge into place. Repeat the previous steps to install the other ink cartridge, if needed. The color ink cartridge is on the left, and the black ink cartridge is on the right.
9. The HP printer software prompts you to align the ink cartridges when you print a document after installing a new ink cartridge. The printer automatically prints an alignment page. Wait for the alignment page to fully eject from the printer.
10. Lift the product lid.
11. Place the alignment page on with the printed-side down on the right-front corner of the scanner glass. See the engraved guide next to the scanner glass for help loading the alignment page.
12. Close the lid, and then touch OK. The product scans the alignment page and completes the alignment process.
13. Discard or recycle the alignment page.
