the main system is faulty same thing happened to me.

Does it say Scanner Failure...?

If then try these steps mentioned bellow:

Remove all the ink cartridges from the All-In-One.
Unplug the power cord from the All-In-One as well as the power outlet.
Now move the carriage (carriage is above the place wher we install ink cartridges it is a metal part which moves in a metal bar) Too and Fro till you feel the carriage is moving smoothly.
Then insert the cartridges close the access door.
Plug the power cord directly to a wall outlet without surg protector.
Before connecting the power cord to the All-In-One press and hold the # and no 6 button and then insert the power cord, do not release the keys
until you see a message a reset (if the screen goes blank then release the keys and turn the power on)
Then if it prompts the ink cartridges insert ink cartidges
Now try printing a test page or make a copy

If it still makes a loud noise and the message comes up as scanner failure, then either the scanner or the scanner machanisum is bad, you may have to replace the unit

Good Luck

The only thing I can surgest is that you check installed programs I found that the 750 is very fussy about being the only kid on the block. Maybe worth trying a commercial program that says it will remove "junk" from your hard drive

Here it is all over, with all the steps.

1.Unplug power cable from printer.

2.Hold Cancel and Enter. OR you could Hold Cancel and Black Copy Button. Whichever is easier

3.Then plug back in the power cable, while still holding those 2 buttons.

4.It should turn on, lights blink, then it should say FULL RESET on the little screen thingy .

5.Let go of the buttons, and hopefully, it fixed your problem.

This seems to be a paper registration problem for the copy function only that is an HP thing Good old HP so innovative and so secretive none of us know whats going on most of the time. Two things to try. Take the stack of paper out of the feed tray and riffle so that it is slightly 'untidy' switch off the device , load the paper, switch on- see what happens. Next look at the software disk- there is usually a fully comprehensive reference manual on there [more than in the book]- check that out then come back.

Checxk the manual for FAQ's Check makers tech help site,looks like a service job
