I have an hp officejet 7310. When I try to print something (fax, document, copy) it says "printing page 1" but freezes. If I hit cancel and try to print again, it usually will print. Then after printing it does it's customary recycling thing and after the print cartridge goes back and forth a few times, I hear this horrible cranking noise and next time I try to print...it freezes again. I can then hit cancel, try again, and usually get one print job done till it makes the same cranking noise and won't print. I have checked for paper jams, etc. Can't figure out what is causing the cranking noise or why that seems to force the printer to freeze.

go to hp.com, support and troubleshooting, type in your pirnter model number and download the user manual. follow the direction to disassemble the printer. you might not need to disasseble the printer, if you can see the jammed paper.
follow the direction and clean the roller and the printer head.
it should work.

To start with first try a reset:

Unplug the power cord from the All-In-One as well as the power outlet when there is still power in the All-In-One. and wait for atleast 1Min
Plug the power cord directly to a wall outlet without surg protector. (if possible connect it to a different power outlet)
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 check and see
