If your HP Officejet Pro 8000 or 8100 does not recognise the ink cartridges, is unable to execute orders or does not print with a proper quality, you might need to reset your printer. To do so, you just need to follow these steps:
- Press the ‘Menu’ button several times until the ‘Setup’ menu appears on the screen.
- Press the ‘Item’ button until ‘Service Message ON-OFF’ is shown on the screen.
- Then select OFF.
- Press SELECT to save and turn the printer off.
- Hold down the ‘-’ button until the message ‘Reset/Main Cont.’ is shown.
