How to Install Ink in an HP 4280 Printer

1. Turn on your HP 4280 printer and load it with paper.
2. Open the ink cartridge door on the front right side of the printer.
3. Remove the HP black ink cartridge from its packaging. Remove the tape from the cartridge.
4. Hold the cartridge in front of the black ink cartridge slot with the electrical contacts facing the back of the printer. Tilt the front of the cartridge slightly downward. Insert the cartridge into the right slot and push it until it locks into place.
5. Repeat the installation process with the HP tri-color cartridge. Close the ink cartridge access door. Wait for the alignment page to print.
6. Place the alignment page face-down on the scanner, aligning it with the right front corner.
7. Push the appropriate command button -- 'Scan' on the F4280 or 'OK' on the C4280 -- on your printer console. Wait until the printer stops making noise. Remove and discard the alignment page.
