1. 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 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. You’ll usually install both the black and tri-color cartridges in the HP ENVY 7645, but you can also leave one ink cartridge carriage empty (single-cartridge mode). During single-cartridge mode, the printer can only copy documents, copy photos, and print jobs from the computer.

2. Load plain white paper into the input tray.
3. Press the Power button to turn on the printer, if it is not already turned on.
4. Open the cartridge access door by placing two fingers under one or both of the small handles on the sides of the cartridge access door and then lifting it up.
The Door Open screen displays on the printer control panel with the message, ‘The cover or door must be closed to print. Check that it is completely closed.’ A Change Ink option also displays on the bottom right corner of the touchscreen.
5. Touch Change Ink to watch a video on the touchscreen about replacing the cartridges (optional).
– Remove the cartridge from the slot on the left to replace the tri-color cartridge.
– Remove the cartridge from the slot on the right to replace the black cartridge.
7. Pull the cartridge toward you out of its slot, and then set it aside for recycling.
10. Slide the new cartridge at a slight upward angle into the empty slot, and then gently push up on the cartridge until it snaps into place.
11. Repeat these steps to insert the other cartridge, if necessary.
12. Close the cartridge access door. When the door is completely closed, the Door Open screen with the message, ‘The cover or door must be closed to print. Check that it is completely closed.’ disappears, and the printer returns to the Home screen.
13. Touch OK.
14. Wait for the printer to calibrate and align the cartridges. After the alignment is complete, the printer prints an alignment page.
16. Follow the instructions on the printer display to align the cartridges, and then discard or recycle the alignment page.
