Perform the following steps to resolve the issue.

1. replace the power cord
   
2. Wait approximately 35 seconds for the scanning assembly to walk out and then quickly remove the plug again.
   
3. Repeat steps 1 and 2, until the head moves approximately 1 inch away from its normal resting place.
   
4. Upgrade The firmware for scanner from HP web site

This part is not available to the public as scanner bulb is not common for all models of hp and its not easy to replace for home user so scanners lams are not user replaceable.Disassemble scanners and again assemble is not easy so for get to do any thing by your self and better to call hp for support
