Can i make copies of a paper


Hello.

If you have a HP DeskJet 6840 then you won't be able to make copies since it doesn't have a built-in scanner. You can buy a scanner separately, scan the document using the scanner and then print it using the HP.

Hp deskjet printer 6840 wont print .keeps on saying top cover is open when it is actually closed.


Pop off the right side cover - it is just held with clips. At the hinge, you will see that the cover switch arm that is supposed to move up and down as the cover opens & closes (in the slot in the geared hinge) is probably broken off. It is in the up position when the lid is closed, and down when the lid is open. I cut the shaft of a Q-tip to length and wedged it into the space to keep the cover switch up all of the time and still allow free movement of the lid.

HP printer doesn't work after clearing a paper jam


If you did not get ALL the jammed sheet out, there is still a small piece of paper in there somewhere, probably covering a sensor or micro switch. Get a torch and look carefully. If youu don't find anything you may need to disassemble the printer to find it. What have you got to loose?
