HP 4515 Scanner does not work. Scanner head goes up but doesn't return

Question

In this PSC ... the scanner is not working ... Have tried everything like updating Drivers etc....  Actually the problem is with Scanner itself because its "Copy" function (on the printer Touchscreen ) which first scans the document and then prints also doesn't scan... it struck on "Now copying" screen... Using scanner under PC, shows scanning and struck there... then I have to restart printer. I have also made a video of this problem ... At https://youtu.be/2bW65iY9z-k Here's what I did in the video  1. Opened the scanner cover.2. Pressed the copy button  and chose to copy a blank page by adding nothing on scanner  to see how scanner head moves.3. Scanner head (with bulb off) moves up to the other end of the scanner.... then it tries to come back and some light also blink but nothing after that. And it is struck there. The printer takes the page but it doesnt start print anything.4. I shut down the printer via Touchscreen ... the printer throws the blank page out .... the scanner head still on the other end.5. I then power off the printer via unplugging it and switch it back on .... the scanner head now comes back to home position Video is at https://youtu.be/2bW65iY9z-k Clearly the scanner head is not jammed because it comes back smoothly after switch-off and again powering on... means the scanner head is moving smoothely up down ... Any suggestion on how to fix that...  Plz dont suggest HP Print and Scan Doctor because it also hangs/struck while scanning... I also tried opening the scanner glass but its not that easy esp in this model as its scanner screws are below the scanner and easy to unscrew all...

Hey , I understand that the scanning mechanism within your HP Deskjet Ink Advantage 4515 e-All-in-One Printer is not functioning properly. I would like to assist you today with resolving this issue. Thank you for including all of the troubleshooting steps that you have attempted prior to reaching out for support. Because your machine is also getting 'stuck' on 'Now Copying', and the scanner bar (bulb) is not responding properly within your machine, I believe that your HP Deskjet is encountering either a power or a Firmware Programming failure, rather then a scanning mechanism hardware failure. With that being said, can I please have you follow the steps below to resolve this issue.   Step 1: Check Power:  Please plug your printer directly into a wall outlet for power. Power strips and surge protectors may cause your printer to lack power and not respond properly. Once your printer has been plugged directly into a wall outlet please test the Copy function. Should Copying still 'stall' on 'Now Copying' please proceed to the next step.   Step 2: Power Reset:  With the printer ON, disconnect the power cable from the rear of your printerLeave the power cable disconnected for 30 secondsPlug the power cable back inYour printer should start back up on its ownOnce your printer returns to the ready state please perform another test Copy. Should Copying standalone still fail, please proceed.   Step 3: Update Firmware:  The Firmware is the internal programming within your printer. Essentially it is the 'brains' of your printer and controls what the printer does and how the printer does it. If the internal programming within your machine is corrupt it may cause performance issues within your product. Please click here for detailed instructions on updating the Firmware from the front panel of your printer. Once the Firmware has been successfully updated please test Copying from the front panel again. Should Copying now work, please attempt a Scan.
  Please respond to this post with the result of your troubleshooting. Should the issue persist, there is an additional programming Reset I will have you perform. I look forward to hearing from you!
