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. 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.
You can check the estimated ink levels from the printer control panel, from the HP printer software, and from the HP Smart App.
To check the ink levels from the printer software (Windows):
– Open the HP printer software.
– In the printer software, click Estimated Levels.
To check the ink levels from the HP Smart App:
Open the HP Smart App on your mobile device. The estimated ink levels for your printer appear at the top of the screen, beside the picture of the printer.
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 Pro 6455 All-in-One Printer with only one ink cartridge. The single-cartridge mode is initiated when there is only one cartridge installed in the carriage, or a cartridge is removed from the carriage if there are two cartridges installed previously.
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.
For your US HP ENVY Pro 6455 All-in-One Printer you need HP 67 Black AND HP 67 Tri-color cartridges OR the XL versions: HP 67XL Black AND HP 67XL Tri-color cartridges.
For your European or UK HP ENVY Pro 6455 All-in-One Printer you need HP 305 Black AND HP 305 Tri-color cartridges OR the XL versions: HP 305XL Black AND HP 305XL Tri-color cartridges.

Align the new cartridges
– 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.
– Lift the scanner lid.
– Place the alignment page on with the printed-side down on the left-back corner of the scanner glass. See the engraved guide next to the scanner glass for help loading the alignment page.
– Discard or recycle the alignment page.
The alignment page did not print?
If the alignment page did not print automatically, you can align the cartridges manually from the printer software and from the HP Smart App.
