Question about HP LaserJet 2840 Printer
When i try to scan the computer screen says check connection the computer and the scanner are having problems communicating. I currently have to cords going from the machine to the computer. What is the problem?
Do you have both the ethernet and the USB cable attached at the same time? I've seen issues where this has been the cause. Pick one connection method and stick with it. I suggest the USB.
