This problem has to do with the scanner mirror. You may hear a grinding sound, also. The reason it does this is because the scanner bulb cannot find 'home', so it keeps trying to find it. Well, it uses the mirrors to reflect on another object inside the scanner to tell it when to stop. The mirror on top of the right next to the scanner bulb may need to be cleaned. This works every time for me, except the same problem always comes back sooner or later.
how to clean-
1.unplug your scanner
2.notice the glass covering on the left side, it can be removed with a Phillips screwdriver. Unscrew the plastic surrounding the glass and then remove the glass covering.
3.Plug the scanner back in and wait for the scanner to move left and then unplug it before it starts moving to the right. Repeat this until scanner bulb is all the way on the left of the machine.
-an alternative method-
with the glass covering removed, use a pair of pliers to move the small belt that moves the scanner bulb. keep moving it until the scanner bulb is all the way on the left of the machine.
4.With the scanner bulb assembly in reach, grab a Q-tip and gently clean the mirror that is just to the right of the bulb. You might want a flashlight to see the dirt and dust.
5. Put the glass covering back on.
6. Plug in the scanner.
At first to me it seemed like it wouldn't work, but it does.
Hope it helps. Reply back if it does.

If you scanner error 5 or printer hangs at scanner bulb warming up than the issue is with Scanning Assembly inside the printer and it is hardware issue.

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
