HP PHOTOSMART 3310

hello, well, you can take off the right cover, with printer unplugged, and disconnect cables that connect to the scanner top cover area. the hinges have press lock that will require you to press up, and slide towards the front and lifting up at same time. the scanner will come off, using #10 torq bit, take hinges out of machine, if you some white grease or light weight lithium oil, use it in and around the actual hinge area, basicly what your working against is plastic on plastic, with a powerful spring, so do this carefully and try not to pinch your fingers, it hurts alot. try slowly to open and close hinge slowly, if it does not move freely, don't force or it will break, that spring used is under alot of pressure, so do it slowly, lube and try to move, lube and try to move. when it works smoothly put back together

hinges seprately cannot be replaced . for support needs you can call hp tech support team 1800-474-6836 ask for printers and ask for the same. if its under factory warranty the entire printer can be replaced//

Is it just stuck? Because if it is just use WD40 on the hinges. If it's broken, then sorry. Can't help you.

Make sure you have successfully seated the cartridges you replaced. They may be preventing the lid from closing.

Same thing happened to my printer last night (never happened before) and I too am looking for some release latch....so frustrating and I don't want to force it closed...

Check back by the hinges there should be a catch that locks the lid up just release the catch. If yours does not have this check to make sure you don't have to lift up again to release the lid. These are the only problems with that type of printer that I've seen, I hope this helps if not let me know and I'll do some research and try to find an answer for you. Good luck.

Good Luck

not really..that's a service level repair that takes around 1.5 hours with the right tools

Sounds like the hing on back is broken. Look on the back of the cover, there will be 2 hinges holding the scanner on. Probably a piece of plactic broke and is hanging up one of the hinges.
Possibly a small spring.
