Core Data Recovery

If the display panel on your HP LaserJet reads “perform printer maintenance”, “perform user maintenance”, or anything along those lines it means your printer needs a preventative maintenance kit. Failure to do so can mean more down time. To clear the error here are the steps. ( I still recommend installing the kit.)

1. Turn the printer off.
2. hold down the check mark button as you turn the power on
3. Continue to hold down the check mark (Select) button until all three LED are illuminated.
4. Release the check mark (Select) button.
5. Press the up arrow (Navigation) button until the message New Maintenance Kit appears on the control panel display.
6. Press the checkmark button once.
7. A message New Maintenance will appear in the control panel display and the printer will reset.

This is done by the tech after installing a maintenance kit to tell the computer inside your printer that it has been installed.
