Question about HP PSC 750 All-In-One InkJet Printer
When we go to scan or copy a paper a message that reads "Scanner Failure: Turn power off and then on again," pops up. We follow as the directions say, turn off and then on again, but the message pops up in a minute or when we try to scan or copy. We have replaced the ink cartridges numerouse times, and have also unplugged and reset the whole printer in many cases, but none of these seem to work.
Turning on and off or doing the re-set thing didn't work for me.
The solution that worked for me: Removing the black bulb cover and cleaning the mirrors.
Open the hinged lid, lift up and out and set aside. This will expose two small screws in back that holds the glass cover on. Remove the two screws. I used a small allen wrench. Carefully lift the gray glass cover up in back and pry loose in front, one corner at the time. Flip the cover over to the right and carefully set aside, keeping it at the same height as the top of the printer. Do not let the ribbon come out. Also, the little screws will fall out so don't lose them. Once you have exposed the inside, the key to everything is to carefully remove the black bulb/mirror cover on top and LEAVE OFF. There are two small slots on top to allow you to do this, or simply pry off from the side. Once removed, clean the mirrors with a q-tip and go ahead and clean the underside of the glass top while you have it off. Flip the glass top back over making sure the ribbon stays in (you may need to feed it back in a little). Snap the glass top back on, front to back, and replace screws. You should be good to go! I sure hope this helps whomever, because this is a great little printer/copier that I almost tossed.

Try this. For me it was making grinding sounds and asking me to clear jam. There was no jam that I could see.
This worked for me. Lay the printer on its side and press the power button. It clears itself .

When my printer developed this problem it was due to the ribbon on the left hand side of the printer becoming raised slightly and blocking the scanner itself from moving. The solution was to open the printer and, on the underside of the scanner, remove the black plastic cover which then allows access to the ribbon. Just slide a blunt knife or similar under the ribbon and pull tight again. Hey presto problem solved.

I just performed the bulb cover removal and mirror cleaning and I'm back in business! My HP 750 hasn't made copies for a month. Wow, I can't believe someone finally solved this issue!
Great instructions, too. Thanks!!

Re-setting the printer and turning on and off may work once or twice but is NOT a permanent fix! Solution 3 (removing the black bulb cover and cleaning the mirrors) is THE solution. Give it a try...you'll be glad you did. It fixed mine!

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.
