HP 4015 NVRAM & hardrive initialization

2. As the printer performs its power-on sequence, press and hold the Menu button until all three lights on the control panel are lit. 
3. Press the back arrow . The message INITIALIZE DISK displays on the control panel. 
4. Press OK. The printer initializes the hard disk and continues the power-on sequence.

You also need to reconfigure any computers that print to this printer to recognize the printer. Initialize NVRAM only when absolutely necessary. In most situations, use a cold reset to return printer to factory defaults but still retain the needed values in the SERVICE menu.
