Normal 0 Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Need to perfrom nvram init on HP 4250


To initialize NVRAM, turn the printer power off. Remove any installed accessories (for example, a stapler/stacker). Turn the printer power on, and then hold down (SELECT button) when the memory count begins. Continue holding down until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds. Press (UP ARROW button). Press the PAUSE/RESUME button (LJ 4200/4300) or the MENU button (LJ 4250/4350). The display should show SKIP DISK LOAD.

The actual error says that the hard drive is bad. I bet that you don't have a hard drive on your printer, so read on...

From the manual

NVRAM initialization
CAUTION Initializing the NVRAM resets the serial number, the event log, the page counts, and
the EIO card (initializing the NVRAM resets SERVICEmenu values to factory defaults). Use the
service menu to restore the serial number and page counts. Also reconfigure any computers that
print to this device so that the computers can recognize the device. Initialize the NVRAM only
when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization
to reset device settings (this will retain the values in the SERVICEmenu).
NOTE Before performing a NVRAM initialization, print a menu map and a configuration page
. Use the information on the configuration page to reset
any customer-set device configuration values that the NVRAM initialization procedure changes.
Take special note of the total page count, maintenance count, and the serial number.
1. Remove any installed accessories.
2. Turn the device off.
3. Turn the device on. When the memory count begins, press and hold the button. Continue
holding down the button until all three device control-panel lights flash once and then remain
on. This might take up to 10 seconds.
4. Press the button.
5. Press the Menubutton. The display should show SKIP DISK LOAD.

It would not surprice me if you have a defective formatter board. This is a very commen problem with this machine. Officialy you have to replace the formatterboard but there is also an other way to fix it. Put the formatterboard in to a preheated oven 190 degrees Celcius (350 fahrenheit) for 8 minutes. 8 out of 10 times it works fine fine and the machine is up and running. If this does not work you still can replace the formatterboard.

HP 4015 NVRAM & hardrive initialization

Solution
A hard disk initialization will erase and reformat the printer's hard disk. Perform hard disk initialization only if an error code displays on the control panel indicating a disk error. Always try initializing the hard disk before replacing it.

1. Turn the printer on. 
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.


CAUTION: Initializing NVRAM resets the serial number, the model number, the event log, the page counts, and the EIO card. Use the SERVICE menu to restore the serial number and page counts. 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. 

 NVRAM initialization
Before initializing NVRAM, print a configuration page and a supplies status page to gather the service menu values

1. Turn the printer on and watch the control panel display. 
2. When the display shows the memory count, press and hold the down arrow until all three lights on the control panel are lit
3. Press the up arrow . 
4. Press Menu . The message SKIP DISK LOAD displays on the control panel. 
5. Press the up arrow until NVRAM INIT is highlighted, and then press OK. The printer initializes NVRAM and then continues its power-on sequence.

daca aceasta procedura nu reuseste, atunci va trebui sa inlocuiesti formatter-ul. daca nu exista hard disk

Good luck
