HP printer initializing.what can i do? - HP LaserJet 1600 Printer

Turn off the HP LaserJet 2840.


Press and hold down the "Enter" and "*" keys on the printer's control panel, and turn the printer back on.


Hold the "Enter" and "*" keys until you see the "Permanent Storage Init" message on the device control panel. Release the two keys to perform the NVRAM initialization. The NVRAM initialization takes just a few seconds, and the "Permanent Storage Init" message remains on the printer's display until the initialization is complete.


Ensure that the "Ready" message on the printer's control panel is visible. You can now connect the printer to your computer and print your documents. If the "Ready" message is not displayed and your printer is still stuck in a loop, turn off the printer and contact HP customer support (see Resources).

• To reset an HP 2840 from your computer, open the HP Toolbox program, click "Device Settings," click "Service," click "Restore" in the Resets section and then click "OK" to confirm the action and restore the printer to its factory defaults.

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

If you're using Vista, this happens all too regularly with HP printers. I've had a few where I have to uninstall everything then re-install to make things work.
Two weeks later the same thing, same process.
Try downloading latest drivers from HP and see if that helps. HP don't admit there's a problem.
Don't seem to have this problem with Epson printers tho.

Introductory cartridges come with the printer and carry special ink formulations intended for printer initialization. During initialization, inks in the introductory cartridges mix with inks in the printer to create a normal ink formulation. After initialization, introductory cartridges can be used in any compatible printer. However, if introductory cartridges that have not been through initialization are installed in a printer that has already been initialized, the printer cannot print
