Hello, I am Alex Pine. I am digital marketing specialist and freelancer. Achieving optimal performance from your HP printer begins with the proper installation of ink cartridges. Wait for the carriage to move to the center, then remove the old cartridge by pressing the release tab. Unpack the new HP printer ink cartridge and gently remove the plastic tape. Slide the cartridge into the corresponding color-coded slot until it clicks into place. Close the ink cartridge access door, and let the printer align the cartridges for best results.
