Change Ink In The HP Envy 4520 Printer
Confirm that your HP Envy 4520 device is in an active state. Stuff some plain white paper into the input tray of the printer. Lift up the cartridge access door until it gets clasped into its spot. Release the ink cartridge by thrusting it out from the lid. Unpack the new HP Envy 4520 ink cartridge from the packet and remove the plastic tape. Smoothly slide in the cartridge until it gets locked into its spot. Load the second cartridge in the same way. Lock the access door and wait till the alignment page prints.
